  • Gut Health and the Microbiome: What We Know, What We Don’t and What Actually Helps

    Gut Health and the Microbiome: What We Know, What We Don’t and What Actually Helps

    The gut microbiome is the community of microorganisms living in the digestive tract. Research increasingly links these organisms with digestion, metabolism and immune function, but the science is complex and many commercial claims go further than the evidence supports.

    There is no single perfect microbiome

    Microbiomes vary substantially between people. Scientists are still working out which patterns are important for particular diseases and which changes are causes, consequences or simply associations.

    Food matters, but claims need perspective

    Diet can influence the gut microbiota. A varied eating pattern containing appropriate sources of fibre is generally consistent with established nutrition guidance for people who tolerate it. Individual digestive conditions can require different approaches, so restrictive diets should have a clear reason rather than being adopted solely to “reset” the microbiome.

    What about probiotics?

    Probiotic effects are strain-specific. Evidence for one organism or condition cannot automatically be applied to every product labelled “probiotic.” The US National Institutes of Health notes that many commercial products have not been studied for health benefits and there are no formal recommendations for or against probiotics in healthy people.

    Safety matters

    Probiotics usually cause only minor effects in healthy people, but rare serious infections have been reported, particularly in people who are severely ill or immunocompromised. People with significant immune problems or serious illness should discuss probiotic supplements with their healthcare team.

    Persistent gut symptoms need assessment

    Ongoing abdominal pain, persistent diarrhoea or constipation, blood in the stool, unexplained weight loss, recurrent vomiting or other concerning symptoms should not simply be blamed on an “unbalanced microbiome.” Appropriate medical assessment can identify conditions requiring specific treatment.

    This article provides general information. Nutrition and digestive advice should be individualised where medical conditions are present.

    A human trial worth understanding

    Wastyk and colleagues’ 2021 study compared diets rich in fibre or fermented foods in healthy adults. The fermented-food intervention increased microbial diversity and reduced several inflammatory markers. This small study measured biological changes; it did not show that fermented food cures autoimmune disease, cancer or dementia. Nor does it establish that a supplement has the same effects as the foods studied.

    A practical approach to gut symptoms

    1. Describe the problem clearly: pain, stool changes, bloating, timing and duration.
    2. Record medicines, recent antibiotics and any food changes.
    3. Change one manageable habit at a time where appropriate, rather than eliminating many food groups.
    4. If increasing fibre is suitable for you, do it gradually and discuss persistent symptoms.
    5. Review whether the change actually helps and whether your diet remains adequate.

    People with bowel narrowing, severe illness or particular digestive conditions may need different food advice. Keto can include fibre-containing low-carbohydrate plants; strict carnivore generally removes these. Feeling better after eliminating foods does not prove that all plants are harmful or that a microbiome has been “repaired”.

  • After Trauma: Understanding Common Reactions, PTSD and the Road to Recovery

    After Trauma: Understanding Common Reactions, PTSD and the Road to Recovery

    After a frightening or life-threatening experience, people can react in very different ways. Distress after trauma is common, but it does not automatically mean someone has post-traumatic stress disorder (PTSD). Many people gradually recover with time and support.

    Common reactions after trauma

    People may experience upsetting memories, nightmares, poor sleep, irritability, anxiety, difficulty concentrating, feeling constantly alert, emotional numbness or avoidance of reminders. Physical symptoms such as a racing heart or muscle tension can occur as well.

    When it may be PTSD

    PTSD involves a persistent pattern of re-experiencing the event, avoiding reminders and heightened arousal that causes significant distress or interferes with daily life. WHO notes that most people exposed to potentially traumatic events do not develop PTSD and that effective treatments are available.

    Treatment can help

    Evidence-based psychological treatments include trauma-focused cognitive behavioural approaches and eye movement desensitisation and reprocessing (EMDR). The appropriate treatment depends on the person, symptoms and circumstances and should be delivered by an appropriately trained professional.

    Supporting recovery

    Helpful basics can include maintaining routines where possible, sleep habits, physical activity, reducing alcohol or illicit drug use and staying connected with trusted people. Nobody should be pressured to describe traumatic experiences before they are ready.

    When to seek help

    Consider professional support when symptoms persist, worsen or interfere with work, relationships, sleep or everyday functioning. Seek urgent help if there is immediate danger, severe inability to function, or thoughts of suicide or self-harm.

    Trauma recovery is individual. This article is general information and is not a diagnosis or substitute for mental-health care.

    Small steps that protect choice

    • Begin with immediate safety, shelter and practical needs.
    • Ask a trusted person for one specific form of help, such as transport to an appointment.
    • Keep a simple record of sleep, distress and activities that have become difficult.
    • Ask a clinician about a trained trauma therapist and available treatment options.
    • Let supporters know whether you want company, practical help or quiet time.

    You do not have to give a detailed account of the event to everyone who asks. A supporter can say, “I can listen if you want, or help with something practical.” Recovery may be uneven, and treatment should respect the person’s pace and preferences.

    When safety comes first

    If there is immediate danger or you may act on thoughts of self-harm, seek emergency help now and stay with a trusted person if possible. In South Africa, 112 from a cellphone connects to emergency services. A community website cannot provide emergency or crisis care.

    Evidence and further reading

    WHO: post-traumatic stress disorder describes the evidence for trauma-focused psychological treatments, including CBT-based approaches and EMDR. Dietary changes may support general nutrition but are not established substitutes for PTSD treatment.

  • Men’s Health Checks: What to Discuss With Your Doctor and Why Prevention Matters

    Men’s Health Checks: What to Discuss With Your Doctor and Why Prevention Matters

    Many health problems are easier to manage when they are identified early. Preventive care is not a fixed checklist for every man: the right tests depend on age, family history, symptoms, medicines and individual risk.

    Start with cardiovascular health

    Blood pressure, smoking, cholesterol, diabetes risk, activity and weight can all contribute to cardiovascular risk. Ask your clinician how often these should be assessed based on your circumstances.

    Cancer screening is individual

    Prostate screening is not simply a universal test at a particular birthday. PSA testing has potential benefits and limitations, so the decision should take account of age, family history, symptoms and personal preferences. Bowel-cancer screening also varies by country and age group. Report persistent changes in bowel habits, unexplained bleeding or weight loss rather than waiting for routine screening.

    Sexual and urinary health

    Erectile difficulties, urinary changes, pain, lumps or other new symptoms deserve appropriate assessment. Erectile dysfunction can have physical, psychological or medication-related causes and may sometimes occur alongside cardiovascular risk factors.

    Mental health counts

    Depression and anxiety do not always look like persistent sadness. Irritability, withdrawal, sleep changes, increased alcohol or substance use and loss of interest can also be signs that someone is struggling. Seek professional help for persistent symptoms or thoughts of self-harm.

    Make the appointment useful

    Bring a medication list, relevant family history and a short list of concerns. Ask what screening is appropriate for you, what your blood pressure and laboratory results mean, and which changes would make the greatest difference to your health.

    This article provides general information and does not replace individual medical advice.

    Understanding the benefits and harms of screening

    Screening means testing someone who does not have symptoms. Investigating new symptoms is different. For PSA testing, an abnormal result is not automatically cancer: further assessment may be needed. Screening can identify some cancers earlier, but can also lead to false alarms, biopsies and treatment of cancers that would never have caused harm. The National Cancer Institute’s PSA fact sheet explains this balance. Ask how the evidence applies to your age, family history, overall health and local services.

    A personal health-check checklist

    1. Write your three main concerns before the visit.
    2. Bring medicine and supplement names, including products bought online.
    3. Record close relatives’ major diagnoses and ages at diagnosis where known.
    4. Ask about blood pressure, diabetes risk, smoking, alcohol, sleep and activity.
    5. Discuss mental health, sexual concerns or urinary changes without embarrassment.
    6. Agree which tests are useful, how results will reach you and when to follow up.

    Do not wait for a screening appointment if you develop a new lump, visible blood in urine or stool, unexplained weight loss or persistent symptoms. Chest pain, stroke signs or severe breathing problems need emergency care. A restrictive diet does not replace screening, diagnosis or prescribed treatment.

    Reading the evidence

    Look for studies that measure meaningful outcomes, such as serious illness and quality of life, rather than treating a changed laboratory number as proof that a test or diet benefits everyone.

  • Palliative Care: What It Is, When It Can Help and Why It Is Not Giving Up

    Palliative Care: What It Is, When It Can Help and Why It Is Not Giving Up

    Palliative care is specialised care focused on improving quality of life for people living with serious illness. It addresses symptoms and distress while also supporting families and caregivers. A common misconception is that palliative care means treatment has stopped or that death is imminent. In reality, it can be introduced alongside other medical treatment.

    What can palliative care help with?

    Depending on the illness and the person’s needs, a palliative-care team may help manage pain, breathlessness, nausea, fatigue, sleep problems and other symptoms. Support can also include emotional, social, practical and spiritual concerns.

    It is broader than end-of-life care

    End-of-life care is an important part of palliative care, but the two terms are not identical. Palliative support can be appropriate much earlier in the course of a serious illness, including while someone is receiving treatment intended to control or treat the disease.

    Who provides it?

    Care may involve doctors, nurses, social workers, psychologists, therapists, counsellors, spiritual-care providers and other professionals. The exact team varies by service and by what the person and family need.

    Planning around what matters to the person

    Serious illness often involves difficult choices. Good communication should help a person understand their condition and options, express what matters to them and participate in decisions as much as they wish. Families may also need guidance about caregiving, changing symptoms and what to expect.

    Questions worth asking

    You can ask whether palliative care is available, which symptoms it can help manage, whether support is offered at home, what caregiver services exist, who to contact after hours and how the team works with existing specialists.

    When illness advances

    When a person approaches the end of life, priorities may increasingly focus on comfort, dignity and care that reflects their wishes. Decisions should be individual and discussed with the treating team. Families should not have to navigate these conversations without support.

    Support for caregivers matters too

    Caring for someone with a serious illness can be physically and emotionally demanding. Palliative care can include education and support for caregivers, not only the patient. Asking for assistance is part of planning safe, sustainable care.

    This article provides general information. Availability and models of palliative care differ between health systems and communities; speak with the treating healthcare team about local options.

    What clinical research tells us

    In a 2010 randomised trial by Temel and colleagues, 151 people with newly diagnosed metastatic non-small-cell lung cancer received standard cancer care with or without early specialist palliative care. The early-care group had better quality-of-life and mood outcomes. This was a specific patient group and care setting, so the results are not a promise of the same benefit for every illness. They do support asking about symptom support early instead of waiting for the last days of life.

    Make a practical care plan

    1. List the symptoms causing the most difficulty and what matters most to the person.
    2. Ask which treatments continue and how the teams will share information.
    3. Keep daytime and after-hours contact numbers together.
    4. Check access to medicines, transport, equipment and home visits.
    5. Ask what caregivers should do if symptoms change suddenly.
    6. Record preferences for future care and review them when circumstances change.

    Comfort-focused nutrition should respect appetite, swallowing safety and personal wishes. Families should not feel pressured to impose keto, carnivore or another restrictive diet on someone who is struggling to eat.

    Further guidance

  • Recognising a Stroke: Warning Signs, Emergency Action and Recovery

    Recognising a Stroke: Warning Signs, Emergency Action and Recovery

    A stroke occurs when blood flow to part of the brain is interrupted or when a blood vessel in the brain ruptures. Brain cells can be injured quickly, which is why recognising the signs and obtaining emergency care without delay matters.

    Know the warning signs

    Sudden facial weakness or drooping, weakness or numbness of an arm or leg, and difficulty speaking or understanding speech are classic warning signs. Other sudden symptoms can include loss of vision, severe imbalance, difficulty walking, confusion or an unusually severe headache.

    If stroke is suspected, treat it as an emergency. Note the time the person was last known to be well and seek emergency medical assistance immediately. Do not wait to see whether the symptoms disappear.

    What about a TIA?

    A transient ischaemic attack can cause stroke-like symptoms that resolve. Temporary symptoms still require urgent medical assessment because they may be a warning of a future stroke.

    What happens at hospital?

    Clinicians need to determine whether symptoms are caused by a clot, bleeding or another condition that can mimic stroke. Brain imaging and other investigations help guide treatment. Some treatments are time-sensitive, but suitability depends on the type of stroke, timing and individual clinical factors.

    Recovery differs from person to person

    Stroke can affect movement, speech, swallowing, vision, thinking, mood, continence and fatigue. Some people recover quickly; others need prolonged support. Rehabilitation may involve physiotherapy, occupational therapy, speech and language therapy, psychological care, nursing and medical follow-up.

    WHO describes rehabilitation as care that optimises functioning and reduces disability, helping people participate as independently as possible in everyday life. Rehabilitation needs can change throughout recovery.

    Reducing future risk

    Depending on the cause, prevention may involve treating high blood pressure, diabetes, abnormal cholesterol or certain heart-rhythm disorders, stopping smoking, taking prescribed medicines and addressing other individual risk factors. Never stop stroke-prevention medication without discussing it with the prescribing clinician.

    Recovery includes the family

    A stroke can abruptly change roles and routines for an entire household. Caregivers may need training, practical support and rest as well. Recovery is not measured only by walking or speech; independence, confidence, communication and participation in meaningful activities also matter.

    Suspected stroke is a medical emergency. This article is general education and not a diagnostic tool.

    Act FAST: a simple emergency checklist

    • Face: is one side drooping?
    • Arms: is one arm weak or unable to stay raised?
    • Speech: is speech slurred, confused or difficult?
    • Time: call emergency services immediately, including when symptoms have stopped.

    FAST does not capture every stroke. Sudden vision loss, severe imbalance or an unusual severe headache can also be warning signs. In South Africa call 112 from a cellphone or 10177 for an ambulance. Note the last time the person was known to be well. Follow emergency instructions; do not give aspirin, food or drink unless a clinician directs you, because bleeding or swallowing problems may be present.

    Planning the first weeks after discharge

    1. Ask for a written medicine list and follow-up appointments.
    2. Check whether swallowing, communication and safe transfers have been assessed.
    3. Request rehabilitation goals based on the activities important to the person.
    4. Agree how caregivers will obtain training, rest and help.

  • Kidney Health: Early Warning Signs, Common Tests and Protecting Kidney Function

    Kidney Health: Early Warning Signs, Common Tests and Protecting Kidney Function

    Your kidneys filter waste and excess fluid from the blood, help regulate electrolytes and blood pressure, and perform several other essential functions. Kidney disease can develop with few symptoms, so people at higher risk may benefit from regular testing.

    Who is at higher risk?

    Important risk factors include diabetes, high blood pressure, cardiovascular disease, a family history of kidney disease and previous kidney injury. Some medicines and medical conditions can also affect kidney function.

    Symptoms may appear late

    Early chronic kidney disease may cause no noticeable symptoms. As kidney function worsens, possible symptoms include swelling of the feet or ankles, changes in urination, fatigue, nausea, itching, poor appetite or shortness of breath. These symptoms have many other possible causes and require proper assessment.

    Two important types of testing

    A blood test measuring creatinine is commonly used to estimate glomerular filtration rate, or eGFR, which provides an indication of kidney filtering function. Urine testing can look for albumin or protein, which may signal kidney damage even when filtration appears relatively preserved. A single abnormal result does not always mean chronic kidney disease; clinicians consider persistence, severity and the broader clinical picture.

    Protecting your kidneys

    Managing blood pressure and diabetes, where present, is particularly important. Avoid smoking, stay appropriately active and discuss medicines with your clinician or pharmacist. Some pain medicines, particularly non-steroidal anti-inflammatory drugs, can pose problems for certain people with kidney disease or dehydration, so ask before using them regularly.

    Hydration is not one-size-fits-all

    Drinking enough fluid is important, but more is not always better. People with advanced kidney disease, heart failure or other conditions may be given specific fluid advice. Follow recommendations based on your own medical situation rather than forcing excessive water intake.

    When to seek urgent help

    A sudden major reduction in urine output, severe weakness, confusion, significant swelling, persistent vomiting, severe shortness of breath or rapidly worsening illness warrants prompt medical assessment.

    Ask for your numbers

    If you are being monitored for kidney health, ask what your eGFR and urine albumin results mean, whether they have changed over time and how frequently they should be repeated. Trends are often more informative than an isolated number.

    This information does not replace personalised medical advice. Kidney treatment depends on the cause, severity and other health conditions.

    Food choices, keto and carnivore

    Kidney nutrition depends on kidney function, blood results and treatment. A high-protein carnivore plan should not be started as a way to “heal” kidney disease. Some people need protein moderation; dialysis may increase protein needs. Potassium, phosphate, sodium and fluids also need individual decisions. Avoid copying someone else’s restrictions or taking electrolyte products without checking their ingredients with your kidney team. NIDDK’s kidney nutrition guidance explains why a renal dietitian can help balance these competing needs.

    Prepare for a kidney review

    • Ask for both your eGFR and urine albumin result, with dates and trends.
    • Bring every medicine, painkiller, supplement and herbal product you use.
    • Discuss blood pressure and diabetes management if relevant.
    • Ask which food or fluid limits actually apply to you.
    • Agree who to contact if vomiting, diarrhoea or another illness stops you drinking normally.

    Do not stop protective medicines or force fluids based on internet advice. A written plan is especially useful when several clinicians prescribe treatment.

  • Breathlessness: Common Causes, Warning Signs and When to Seek Medical Help

    Breathlessness: Common Causes, Warning Signs and When to Seek Medical Help

    Breathlessness can range from feeling slightly winded to feeling as though you cannot get enough air. It may occur with exertion, at rest, suddenly or gradually. Because the lungs, heart, blood and nervous system all contribute to breathing, there are many possible causes.

    Common causes

    Respiratory causes include asthma, respiratory infections, chronic obstructive pulmonary disease and other lung conditions. Breathlessness can also occur with heart disease, anaemia, blood clots, anxiety or panic, deconditioning and a range of less common conditions. More than one factor may be present at the same time.

    When breathlessness is an emergency

    Seek urgent medical care for severe or rapidly worsening difficulty breathing, blue or grey lips or skin, confusion, fainting, significant chest pain, coughing up blood, or breathlessness accompanied by signs of a serious allergic reaction. Sudden unexplained breathlessness also deserves urgent assessment, particularly when accompanied by chest pain, a very fast heartbeat or one-sided leg swelling.

    What a clinician may ask

    Useful details include when the problem began, whether it is getting worse, what triggers it, whether you wheeze or cough, whether you have fever or chest discomfort, and whether you become breathless when lying flat. Tell the clinician about smoking or vaping, recent infections, travel or immobility, medications and existing heart or lung conditions.

    Possible investigations

    Depending on the situation, assessment may include oxygen saturation, examination of the heart and lungs, blood tests, an ECG, chest imaging or lung-function testing. Not everyone needs every test; the pattern of symptoms and examination findings guides the investigation.

    Living with chronic breathlessness

    If breathlessness is caused by a long-term condition, treatment should address the underlying cause. Pulmonary rehabilitation, appropriate physical activity, breathing techniques and correct inhaler use can be important for some people. Ask for your inhaler technique to be checked periodically if you use one.

    Do not assume it is anxiety

    Anxiety can cause genuine breathlessness and can amplify symptoms from other conditions, but new or unexplained breathing difficulty should not automatically be attributed to anxiety. A medical assessment can help determine what is happening.

    This article is general information. Severe or sudden breathing difficulty requires urgent medical attention.

    What to do while arranging help

    If breathing is severe, suddenly worsening, or accompanied by collapse, chest pain or confusion, call emergency services now. In South Africa, call 112 from a cellphone or 10177 for an ambulance. Follow the dispatcher’s instructions and avoid driving yourself. Sit in a position that makes breathing easier and use your own prescribed rescue treatment according to your action plan. Do not borrow medicines or assume that breathing exercises will treat an unknown cause.

    A useful symptom record

    1. Write down whether symptoms began suddenly or gradually.
    2. Describe what you could do before and what you can do now, such as walking to the bathroom.
    3. Note fever, cough, wheeze, chest pain, ankle swelling or difficulty lying flat.
    4. List recent surgery, prolonged travel, infections and medicine changes.
    5. Bring inhalers and ask someone to check technique.

    A home oxygen reading cannot explain the cause or reliably rule out a serious problem. Seek help for worrying symptoms even when a device gives a reassuring number.

  • Understanding Type 2 Diabetes: Blood Sugar, Symptoms, Testing and Everyday Management

    Understanding Type 2 Diabetes: Blood Sugar, Symptoms, Testing and Everyday Management

    Type 2 diabetes is a long-term condition in which blood glucose levels become too high because the body does not use insulin effectively and, over time, may not produce enough insulin to meet its needs. It can develop gradually, which means some people have few or no obvious symptoms at first.

    What does insulin do?

    Insulin is a hormone made by the pancreas. It helps glucose move from the bloodstream into cells, where it can be used for energy. In type 2 diabetes, cells become less responsive to insulin. The pancreas initially tries to compensate by producing more, but this may become insufficient.

    Possible symptoms

    Symptoms can include increased thirst, frequent urination, unusual tiredness, blurred vision, recurrent infections, slow-healing wounds and unexplained weight loss. These symptoms are not specific to diabetes, so testing is important rather than trying to diagnose yourself.

    How is diabetes tested?

    Clinicians may use tests such as fasting blood glucose or HbA1c, which reflects average blood glucose over the preceding months. The appropriate test and diagnostic thresholds depend on the clinical situation. People who are pregnant are assessed differently for gestational diabetes.

    Why management matters

    Persistently high blood glucose can damage blood vessels and nerves. Over time, diabetes can increase the risk of cardiovascular disease, kidney disease, eye problems, foot complications and other health problems. Regular monitoring helps identify changes before complications become more serious.

    Treatment is individual

    Management can involve nutrition, physical activity, weight management where appropriate, stopping smoking, medicines that lower glucose, and sometimes insulin. Blood pressure and cholesterol are also important because cardiovascular risk is a major part of diabetes care. There is no single eating pattern that is suitable for everyone; treatment should take account of medications, kidney function, other conditions, preferences and access to food.

    Everyday checks that matter

    Keep scheduled blood tests and reviews, take medication as prescribed, and ask how often your eyes, kidneys and feet should be assessed. If you monitor glucose at home, make sure you understand your individual target range and what to do when readings are unexpectedly high or low.

    Know the urgent warning signs

    Severe drowsiness, confusion, persistent vomiting, significant dehydration, difficulty breathing or loss of consciousness require urgent medical assessment. People taking insulin or certain glucose-lowering medicines should also know the symptoms and treatment of hypoglycaemia.

    A condition that can be managed

    A diagnosis of type 2 diabetes can feel overwhelming, but management is not about perfection. Consistent follow-up, appropriate treatment and sustainable changes can substantially reduce the risk of complications. Ask your healthcare professional to explain your results, targets and treatment plan in terms you understand.

    This article provides general information and is not a substitute for individual medical advice, diagnosis or treatment.

    Where low-carbohydrate and ketogenic diets fit

    Lower-carbohydrate eating can be one option for type 2 diabetes, but it is not required and it is not a cure. A 2021 systematic review of randomised trials found improved remission outcomes at six months under some definitions, with less clear advantages at twelve months. Results depended on how remission was defined, including whether medication was allowed. Low carbohydrate and ketogenic diets were not interchangeable across the studies, and the findings do not establish benefits for an all-meat diet.

    Before reducing carbohydrate substantially, ask the prescriber to review insulin and sulfonylureas because low blood glucose can occur. SGLT2 medicines need specific advice: ketoacidosis can occur even without very high glucose. Never change doses on your own. Food access, enjoyment, kidney function and long-term nutritional adequacy should help decide the plan.

    Your next appointment checklist

    1. Bring your medicine list and glucose readings, if you monitor them.
    2. Ask for your HbA1c target and when to repeat the test.
    3. Agree on what to do for low glucose, illness or missed meals.
    4. Check when your feet, eyes, kidneys, blood pressure and cholesterol need review.
    5. Choose one realistic food or activity change and an agreed review date.

  • I Knew I Had to Leave

    I Knew I Had to Leave

    A personal story by Soulsearcher. The featured image is an illustration, not a photograph of the events.

    During COVID, my regular infusions had to be done at home.

    Going into hospital carried its own risks. Hospitals were overwhelmed, wards were under quarantine, and because of my health problems, avoiding unnecessary exposure seemed the safest option.

    A registered nurse would come to my home, administer my infusion and, because I was at home, I could continue working at the same time.

    On this particular day, everything started normally.

    The infusion finished, the nurse stayed for a while and then left. I went back to work.

    It was probably around five in the afternoon when something began to feel wrong.

    My muscles started cramping.

    First my legs and arms. Then breathing became difficult.

    At that stage, nobody knew that I had a serious problem maintaining my potassium levels. We would later discover extremely high aldosterone levels and learn that my body was losing far more potassium than it should.

    I would see specialists. I would undergo investigations and genetic testing.

    But ultimately there would be no simple explanation for why my body did this.

    That evening, however, I knew none of that.

    I only knew that my body was shutting down.

    Eventually I was on the floor.

    I couldn’t use my muscles properly. I couldn’t stand. Even my tongue would not cooperate when I tried to speak.

    All I could do was lie there and concentrate on breathing.

    Breathe in.
    Breathe out.
    Keep breathing.

    My father eventually came to check on me.

    At that time, my mother had not yet been diagnosed with Alzheimer’s. She and my father somehow managed to get me up, carry me to the car and rush me to the nearest emergency department.

    I was assessed immediately.

    The doctor on duty called a cardiologist. He looked at my ECG and vital signs and told the other doctor that there appeared to be a blockage.

    He said he needed to operate.

    I was lying on the bed, barely able to move or speak, with nurses around me.

    And something inside me became absolutely clear.

    No.

    I cannot explain it better than that.

    I knew I had to leave.

    I knew I needed to get to the hospital where I was normally treated.

    There was no careful reasoning behind it. I wasn’t in a condition to analyse medical information or weigh up alternatives.

    It was simply an extraordinary certainty.

    I could not stay there.

    The medical staff did not want me to leave because I was unstable.

    I fought them.

    I swore.

    With enormous difficulty, I managed to make it clear that I was refusing treatment there and wanted to be transferred.

    I signed a waiver.

    I remember thinking that I would rather take the risk of dying on the way to the other hospital than allow them to operate on me.

    Looking back, that sounds extreme.

    But in that moment, I had no doubt.

    Something was telling me to go.

    When I arrived at the other hospital, another cardiologist looked at my ECG.

    His response was immediate.

    Potassium.

    I was given potassium intravenously and more potassium to drink in orange juice. Blood was taken.

    The treatment continued, followed by more blood tests and another ECG.

    Eventually, my ECG returned to normal.

    There was no blockage.

    My heart had been struggling because my potassium level was dangerously low.

    My potassium level was 2.2 — dangerously low and well below the normal range.

    I later underwent further testing to determine whether I had suffered a heart attack. I hadn’t.

    A scan of my heart revealed something else I hadn’t known. I was told my heart was smaller than average, but the measurement they used for the strength of my heart was 7.5, when I was told the upper end of the normal range was 5. The cardiologist explained that the strength of my heart muscle had helped me survive what had happened.

    I had survived.

    Later came the search for an explanation.

    Specialists. Tests. Genetic investigations. Questions about aldosterone and why my body was losing so much potassium.

    Some answers came.

    Others never did.

    But there is another question from that night that medicine cannot really answer for me.

    Why was I so certain that I had to leave?

    I had no medical knowledge telling me that the diagnosis was wrong.

    I could barely move.

    I could barely speak.

    I had just been told that there was a blockage in my heart and that I needed an operation.

    Logically, that should have been the moment when I surrendered control and allowed the doctors to do whatever they believed was necessary.

    Instead, something in me said:

    Go.

    And I listened.

    I don’t know whether it was instinct, intuition, fear, some subconscious awareness—or simply one of those decisions we make in extreme circumstances that we only understand afterwards.

    I don’t want to pretend that I know.

    What I do know is that I left.

    At the second hospital, they found the problem.

    And that night, once again, my life continued.

    This is Soulsearcher’s recollection of a medical emergency, including test measurements as remembered. It has not been verified against medical records and should not be used to interpret someone else’s results. Severe low potassium can cause dangerous heart rhythms and needs medical treatment; do not try to correct it yourself. If care concerns arise during an emergency, request a senior review and a medically arranged transfer where needed rather than leaving without safe support. See MedlinePlus on low potassium.

    The White Birds

    A personal story by Soulsearcher. The featured image is an illustration, not a photograph of the events.

    It was just another day after work.

    At about six in the evening, I was driving to fetch a friend from work. It was summer, so it was still light, and there was almost no traffic on the road.

    I approached an intersection and drove through a green light.

    Then I looked to my left.

    A truck was speeding directly towards me.

    It wasn’t stopping at the red light.

    There was no time to think.

    The truck appeared to be travelling at around 120 kilometres per hour. I was doing approximately 35.

    All I could do was take my foot off the accelerator and turn the steering wheel to the right.

    Then came the impact.

    After that, there is nothing.

    I was unconscious and have no memory of what happened immediately afterwards.

    The next thing I remember is people trying to get me out of my car.

    It was smoking.

    They had to pry the door open.

    Three airbags had deployed, and fortunately I was sitting in a bucket seat.

    My car had travelled roughly 100 metres from the point of impact and ended up wrapped around a pole.

    When I regained consciousness, I suddenly felt terrible pain in my left shoulder and neck.

    And then, strangely, very little.

    Apart from seat-belt burns and an injury to my hand, I seemed remarkably intact.

    My left hand had become trapped between the steering wheel and the shattered windscreen at the twelve o’clock position.

    I was extremely dizzy.

    I later learned that the truck had continued after hitting me. It took out two lamp posts on the other side of the road, struck and wrote off a Toyota Land Cruiser bakkie parked near a petrol station further down the road, and eventually came to a stop near the petrol pumps.

    Looking at what had happened, it was difficult to understand how I had walked away.

    Maybe it was the concussion.

    Maybe it was shock.

    But I remember feeling strangely calm.

    I reached through the crushed metal around the roof and left side of the car and managed to retrieve my keys and purse.

    Then I got out.

    That was when the dizziness really hit me.

    I sat down on the pavement.

    And I looked at my car.

    It was destroyed.

    Completely crushed—except for the area around my bucket seat.

    Blood was dripping from my hand.

    And then something happened that I have never forgotten.

    Across the road was a beautiful tree.

    I found myself looking at it.

    Suddenly, around a hundred white birds flew out of the tree.

    They were unlike any birds I remembered seeing before.

    They rose together, circled, and then returned to the tree.

    I watched them.

    Then they did it again.

    They flew from the tree, circled, and returned.

    And then a third time.

    The birds rose together, made another circle and landed back in the tree.

    After the third time, they flew away.

    I just sat there watching them.

    For a moment, everything else seemed to disappear.

    The destroyed car.

    The blood.

    The people.

    The noise.

    The fact that only moments earlier I had been hit by a truck travelling at enormous speed.

    There were just these white birds.

    A woman who had witnessed the accident came and sat beside me.

    I turned to her and asked:

    “Did you see that?”

    She said yes.

    Then she told me something that has always mattered to me when I remember that moment.

    She had never seen anything like it either.

    So I know the birds weren’t something I imagined while concussed.

    Someone else saw them too.

    I don’t know what kind of birds they were.

    I don’t know why so many of them were sitting in that particular tree.

    I don’t know why they took off, circled and returned three times before finally disappearing.

    There may be a completely ordinary explanation.

    But sitting on that pavement beside the wreckage of my car, bleeding and dizzy, having somehow survived an accident that could very easily have ended differently, it did not feel like an ordinary moment.

    It felt incredibly still.

    Almost as though, for those few minutes, everything had slowed down.

    I have never forgotten those birds.

    Just as I have never forgotten the blue-white light from another experience in my life.

    And just as, years later, I would never forget the woman who appeared beside my hospital bed wearing a large owl pendant.

    Three completely different experiences.

    A light.

    White birds.

    An owl.

    And there is something else they share.

    They appeared at moments surrounded by chaos.

    And somehow, in each of those moments, there was peace.

    I don’t know what that means.

    Perhaps one day I will.

    Perhaps I never will.

    But I know what I saw.

    And this time, someone else saw it too.
