Preventive health check-up: how to prepare one that is actually useful

Many health systems offer a structured prevention appointment at certain ages, which is a good place to start. In England, the NHS Health Check is a free check of heart and blood vessel health for people aged 40 to 74 without an existing cardiovascular condition, offered every five years.

France, where MyTwin operates today, has two schemes covered by the national health insurance. Mon bilan prévention (“My prevention check”) is a 30- to 45-minute conversation about lifestyle habits with a doctor, nurse, pharmacist, physiotherapist or midwife, offered once in each of four age brackets (18–25, 45–50, 60–65 and 70–75), and it ends with a personalized prevention plan. The Examen de prévention en santé (“preventive health examination”) is open from age 16, with priority for people who have drifted away from regular care: a risk questionnaire, lab work and tests chosen for the person, then a medical consultation to explain the results.

Eligibility rules change, so check the official pages in your country when you apply. Outside these programs, your primary care doctor remains the natural person to take stock with.

Before the appointment, write down in one sentence what you expect: resuming regular follow-up after several years, updating your vaccinations, discussing family history, preparing to return to sport or checking which screenings apply to you.

Not knowing where to start is often what makes people put the whole thing off. That is what Claire, 47 describes: “everything seems like a priority so I do nothing.” A single sentence stating your goal is enough to get started; the rest of the method is built around it.

If you have a new, persistent or worrying symptom, the process is no longer purely preventive: the professional needs to assess the clinical situation, and you prepare differently. That is what our guide on how to prepare for a doctor’s appointment covers. Chest pain, severe difficulty breathing or sudden neurological signs are not for a scheduled check-up: call your local emergency number.

Put together a short, dated list:

• prescribed treatments, over-the-counter medicines and supplements;
• allergies and reactions you have already had;
• relevant personal and family medical history;
• surgeries, hospital stays and recent tests;
• known vaccinations;
• smoking, alcohol, physical activity, sleep and diet, without trying to present an “ideal” version;
• recent changes in weight, tiredness or symptoms to discuss.

For treatments, an up-to-date medication list prevents omissions. For documents, bring the reports that matter rather than a disorganized archive: our method for organizing a personal health record helps you sort them by date.

Your own measurements

A smartwatch or a home blood pressure monitor can provide a useful history, as long as it is put in context: which device, measurement conditions, frequency, related symptoms. Do not draw conclusions on your own from an alert; show a trend and the underlying data instead. What health wearables measure well, and less well, has its own article.

Screening is aimed at people without symptoms. As the WHO Regional Office for Europe puts it, its purpose is to identify people in an apparently healthy population who are at higher risk of a health problem, so that an early intervention can be offered. A diagnostic test, by contrast, responds to a clinical suspicion. Confusing the two can lead to false reassurance or to a cascade of further tests.

The same WHO guide notes a growing trend towards screening and health checks in Europe, too often without a clear evidence base, and a limited awareness of their potential harms. Useful screening rests on evidence, a target population, a set interval and a pathway to confirm results. Organized cancer screening programs follow this logic; in France, the National Cancer Institute (INCa) lists them cancer by cancer, and most countries publish their own.

For every test you are offered, ask:

• why it is being suggested in your case;
• what a normal or abnormal result would mean;
• what its limits are;
• what the next step would be.

A check-up can raise several topics. Sort them by urgency, importance and your ability to act. A simple plan fits in a few lines: an appointment to book, a vaccination to update, a measurement to confirm, a habit to work on and a date to review things.

Prevention is not just screening. It also covers reducing exposures, mental health, dental health, sleep, physical activity, diet and accident prevention. Not all of these actions are medical, but they should still fit your situation. Where a check-up captures a moment, predictive health looks at how data changes over time to estimate a risk.

With MyTwin for patients, your reports, lab results and treatments are brought together in a single app and presented chronologically, and partner prevention technologies let you get started at your own pace, without tackling everything at once. Choosing the tests and interpreting the results remain the job of the professional who follows you.

Note each decision, who made it, its date and its deadline. Keep the original results. If no action is needed, note when the topic should be reviewed. A clear summary avoids repeating tests unnecessarily and makes handovers between professionals easier.

If lab results reach you before you have discussed them with a professional, our guide on how to read blood test results explains how to go through them without drawing conclusions on your own.
