Many people develop high blood pressure, or hypertension, as they get older. The cause of high blood pressure is unknown in most cases, though it tends to run in families. Hypertension does not cause symptoms, but over many years it will damage blood vessels leading to an increased risk of stroke, heart disease, kidney disease, dementia, and circulation problems.
Healthy weight, regular exercise, and limited salt in your diet can help control blood pressure. When these lifestyle changes do not adequately control blood pressure, there are many medications that can be used.
