High blood pressure: what to monitor and test

Why continuous monitoring matters

Hypertension is a major risk factor for heart disease, stroke and chronic kidney disease. Most people with high blood pressure feel nothing, so it is often found during a health check or after complications appear.

A single reading does not confirm the diagnosis. Doctors usually repeat measurements at different times and may ask you to measure at home, because the clinic setting itself can raise readings (white coat effect).

Tests doctors commonly order

Additional tests look for contributing causes, assess organs that may already be affected, and make treatment safer.

• Kidney function and blood electrolytes (creatinine and electrolyte)
• Blood sugar and lipids to assess combined cardiovascular risk
• Urine analysis for protein or early signs of kidney damage
• Electrocardiogram (EKG) where indicated
• Testing related to other conditions such as diabetes or family history of heart disease

What to tell your doctor every visit

Managing blood pressure depends on complete information. Bring the following to every appointment:

• All medicines, including cold remedies, painkillers and supplements, since some raise blood pressure
• Your home readings and the times you measured
• Any symptoms such as severe headache, blurred vision, chest pain or leg swelling
• Changes in weight, sleep and stress levels

Lifestyle changes alongside treatment

Reducing sodium, controlling weight, regular aerobic exercise, stopping smoking and limiting alcohol genuinely lower blood pressure and help medication work better.

Measure correctly: sit quietly for at least five minutes, keep the arm at heart level, do not talk during the measurement, and repeat once to confirm. Record the values to show your doctor.
