The people who get the most out of medicine are often the ones who come in when nothing is wrong. It sounds backwards. It is the whole point of preventive care.
Most of the conditions that shorten lives in Trinidad and Tobago, high blood pressure, diabetes, high cholesterol and several cancers, do their early damage in complete silence. By the time they announce themselves with symptoms, the easy years for treating them have often passed. A check up is simply a way of listening for them before they speak.
What preventive medicine really is
Preventive medicine is the part of healthcare aimed at stopping illness or catching it early, rather than only treating it once it causes trouble. It covers three simple things: measuring the numbers that predict disease, screening for cancers while they are curable, and keeping vaccinations up to date.
The reason it works is arithmetic. A blood pressure caught early is managed with lifestyle and a tablet. Left for years it damages the heart, kidneys and brain and leads to a stroke. The same pattern holds for diabetes, cholesterol and most cancers. Early is cheaper, simpler and kinder.
The core numbers everyone should know
A handful of measurements do most of the work of predicting future illness, and none of them can be felt.
Blood pressure is the force of blood against your artery walls. Raised blood pressure, or hypertension, usually causes no symptoms at all, which is why it is often called the silent killer. A simple painless measurement finds it.
Blood sugar. A blood test shows whether your sugar is drifting toward diabetes. Caught at the pre diabetes stage, the condition can often be turned around with diet, weight loss and activity before it ever becomes diabetes.
Cholesterol. A blood test measures the fats in your blood that, over years, silently narrow the arteries and lead to heart attacks and strokes. Our laboratory runs this alongside other routine bloods in one visit.
Weight and waist. Not vanity, but a strong signal of future risk, and one you can act on.
What to screen for, by stage of life
Screening is not one size fits all. What matters changes with age, and these are general guides rather than fixed rules, since your family history and personal risk can move the timing.
In your twenties and thirties
This is the foundation stage. Have your blood pressure checked, know your weight, and keep vaccinations current. Women should begin cervical screening in this period, a simple test that looks for early changes on the cervix long before they could become cancer, and continue at the recommended intervals. It is a good age to set the habits that make the later decades easier.
In your forties
The metabolic conditions start to appear now, often without any warning. This is the decade to add regular blood sugar and cholesterol testing to your blood pressure checks. Women continue cervical screening and should start discussing breast awareness and, at the right age, breast screening. It is also a sensible time to consider a broader check up if you have never had one.
Fifty and beyond
Cancer screening moves to the centre now. Bowel cancer screening becomes important for adults at average risk from around this age, and a colonoscopy, a camera examination of the large bowel that can find and remove growths before they turn cancerous, is available here. Men should have the conversation about prostate screening, earlier if it runs in the family or for men of African and Afro Caribbean descent. Blood pressure, sugar and cholesterol checks continue, and eye and bone health deserve attention too.
The executive medical: everything in one visit
For many busy people the barrier is not willingness but time. An executive medical is a thorough, pre arranged check up that bundles the consultation, blood pressure, a full panel of laboratory blood tests, and appropriate imaging into a single organised visit, with the results explained to you together. Because our laboratory, imaging and consulting rooms are on one site, it can genuinely be done in one place rather than across weeks.
What we can actually check here
A check up is only useful if the tests it points to are within reach. At Newtown they are, under one roof.
The laboratory handles blood pressure related bloods, blood sugar, cholesterol, kidney and liver function and much more. Imaging covers X-ray, ultrasound and CT scanning to look inside the body when a symptom or a result calls for it. Endoscopy and colonoscopy let a doctor look directly inside the digestive tract and take samples. When something is found that needs it, our operating theatre and specialist clinics are here, and we refer onward for the few services we do not provide.
What to do next
If you cannot remember your last blood pressure or blood sugar reading, that is your answer: it is time for a check up. Book one while you feel well, bring any past results you have, and ask which screenings are due for your age. The best day to look for a silent problem is a day you feel completely fine.
Feeling fine is the best time for a check up. Book one at Newtown.
Blood pressure and blood sugar checks, cholesterol and other laboratory work, executive medicals, X-ray, ultrasound and CT scanning, and endoscopy and colonoscopy are all available under one roof at 55 Woodford Street, Port of Spain, so a full assessment can often be done in a single visit. Book a check up while you feel well. Our Accident and Emergency department is open 24 hours if something cannot wait.
