Heart & CirculationHigh blood pressure (hypertension)
High blood pressure usually has no symptoms, but it can raise the risk of heart attack, stroke, and kidney disease. Learn how it is checked, treated, and monitored.
Heart & CirculationHigh cholesterol
High cholesterol rarely causes symptoms, but a blood test can show whether treatment could lower your risk of heart attack and stroke. Learn about tests, lifestyle changes, and medicines.
Heart & CirculationPeripheral artery disease
Peripheral artery disease (PAD) is narrowing of the arteries supplying blood to the legs (and sometimes arms), caused by atherosclerosis. It reduces blood.

A stroke happens when blood flow to part of the brain stops. Learn the FAST warning signs, why every minute matters, and how treatment and recovery begin in hospital.
