Lifestyle and longevity medicine in Cape Town
Nutrition, movement, sleep and stress brought into one plan, read alongside the metabolic markers that show how you are doing. The aim is healthspan, the years lived well, with changes that are small, specific and reviewed against your own results. I see patients at practices in Big Bay and Blouberg.
Who this is for.
- People who want to understand their metabolic health before problems appear.
- People with raised blood pressure, blood sugar or cholesterol who want to use lifestyle as part of treatment.
- People with a family history of diabetes, heart disease or high blood pressure.
- People who are tired, sleeping badly or under constant stress, and want to know what is behind it.
- People who have tried generic plans without lasting change.
- People who want nutrition, movement, sleep and stress considered together instead of one at a time.
Concerns people bring.
- Blood sugar or HbA1c that is borderline or rising.
- Cholesterol, blood pressure or waist measurement that is creeping up over the years.
- Tiredness, poor sleep or low energy with no clear cause.
- Long working hours, constant stress or very little time for yourself.
- Eating patterns, alcohol use or a mostly sitting day you would like to change.
- Results you have been given but are not sure how to read.
How the work is done.
The aim is healthspan, the years lived well, rather than lifespan alone. Each stage builds on the last.
-
A full history
Your symptoms, medical and family history, medicines, sleep, nutrition, activity, alcohol, stress, work and home life. The aim is to understand what is realistic for you.
-
Proper baseline data
Metabolic markers, body composition and risk assessed together and read alongside your habits, so that changes are chosen for a reason and can be checked later.
-
A plan reviewed over time
A few specific changes at a time, agreed with you and revisited at follow-up. The plan changes as the data does, and habits last when they are built in steps.
Your first visit.
The first visit is mainly a conversation. You are asked about your symptoms, your own and your family's medical history, your medicines and supplements, and your sleep, food, activity, stress and an ordinary week in your life. Recent results are read with you.
Measurements and tests are discussed against your history. If further tests would help, the reasons are explained before they are arranged, and the results are talked through with you at a follow-up visit. If another professional, such as a dietitian or biokineticist, would help, that is discussed with you.
What this is not.
- Not an anti-ageing service. No treatment stops ageing, and no claim of reversing it is made here.
- Not a diet, a detox or a fitness programme, and not a fixed package with a promised result.
- Not a replacement for medicine where medicine is needed. Never stop a prescribed medicine without speaking to your doctor.
- Not a substitute for emergency care. For a medical emergency, call 10177 or 112.
What the evidence can and cannot do.
Longevity medicine is a young field, and not every claim made online is supported by good evidence. The approach here is evidence-based. It focuses on measurable risk factors where research supports acting on them, and says plainly where the evidence is limited. Lifestyle change works alongside medicine where medicine is needed, and never instead of it. There is no quick fix and no guaranteed outcome.
Common questions.
What is metabolic health?
Metabolic health describes how well the body manages and uses energy. It is often understood by looking at blood glucose, blood fats, blood pressure, waist measurement and liver health together, rather than at one number alone.
Is this about living longer?
The aim is healthspan, the years lived well, rather than lifespan alone. Many of the same steps that protect long-term health also affect how you feel today.
Is this a diet?
No. It is a plan covering food, movement, sleep and stress, built around your life and reviewed over time.
Do I need to be unwell to come?
No. Many people come to understand where they stand before anything has gone wrong. If you do have symptoms or a diagnosis, those are considered first.
Do I need a gym membership?
No. Movement is planned around what you can and will do, including what fits into an ordinary day.
Can other professionals be involved?
Where a dietitian, biokineticist, psychologist or another professional would help, referral is discussed with you.
How long before I notice a difference?
It varies from person to person. Progress is checked at follow-up against your own measurements rather than a fixed timetable.
What should I bring?
Any recent blood results, a list of your medicines and supplements, and what you know of your family history. If you are not sure what is relevant, bring what you have.
Will I need blood tests?
Blood tests are often useful, but which ones depends on your history and what you already have. The reasons are explained first, and you can ask questions before agreeing to any test.
Do you recommend supplements or special diets?
Recommendations are based on evidence and on your own results, and are explained with their benefits and limits. Nothing is suggested because it is fashionable.
Can I do this if I have a long-term condition?
Yes. Lifestyle change is often part of managing conditions such as high blood pressure, prediabetes or raised cholesterol, and it works alongside any treatment you are on.
I sleep badly. Is that something you look at?
Yes. Sleep affects appetite, blood sugar, blood pressure and mood, so it is treated as part of the plan and not as an extra.
