Prevention: what actually lowers your risk

Prevention is less about avoiding every risk and more about catching problems while they are still small and treatable. Three tools do most of that work: screening, vaccination, and paying attention to changes in your body.

Screening finds problems early

Screening tests look for disease before you feel symptoms, when treatment tends to work best. Which tests apply to you depends on your age, sex, family history, and existing conditions.

• Blood pressure — checked regularly; high blood pressure usually has no symptoms.
• Blood sugar and cholesterol — periodically, especially with a family history or higher weight.
• Cancer screening — such as cervical, breast, and colorectal screening, at the intervals appropriate for your age and risk.

Vaccination

Vaccines are among the most reliable preventive tools available. Beyond childhood immunisations, adults may need boosters, an annual flu vaccine, and other vaccines depending on age, occupation, travel, and health conditions. Ask me which ones apply to you.

Know the symptoms that need prompt attention

Some symptoms should never be left to see if they settle on their own. Seek urgent care for:

• Chest pain or pressure, or sudden breathlessness
• Sudden weakness or numbness on one side, facial drooping, or slurred speech
• Sudden severe headache unlike any you have had before
• Coughing up blood, or blood in stool or urine
• Unexplained weight loss, a persistent lump, or a sore that will not heal

Manage what you already have

If you live with diabetes, hypertension, or another chronic condition, consistent management is itself prevention. Steady control of blood sugar and blood pressure prevents the complications that cause the most harm over time.

When you are unsure

A teleconsultation is a low-friction way to ask whether something is worth investigating. It is always better to ask early about a symptom that turns out to be nothing than to wait on one that is not.
