High blood pressure is increased pressure of blood inside the blood vessels. Too much pressure causes more work for the heart. Another name for high blood pressure is hypertension. About one in three American adults has hypertension and about half of them do not know they have this health problem.
Hypertension can cause the following:
Atherosclerosis (narrowing and hardening of blood vessels)
Damage to the eyes
You are at higher risk of developing hypertension if you:
are a man
are 45 years of age or older
eat a high-sodium diet
had a parent with hypertension
drink large amounts of alcohol
are not physically active
Blood pressure is measured as two numbers—the systolic (sis-TOL-ik) and diastolic (di-ah-STOL-ik) pressures. Blood pressure is measured as millimeters of mercury or mmHg. The two numbers are written as systolic “over” diastolic, such as 120/80 mmHg. Most people should aim for a blood pressure less than 120/80 mmHg. This means systolic pressure should be less than 120 mmHg and diastolic pressure should be less than 80 mmHg.
Often there are no symptoms of high blood pressure. Checking your blood pressure is the only way to know if your blood pressure is high. Have your blood pressure checked by a doctor or other health professional at least once a year. The Elder Nutrition and Food Safety (ENAFS) program's Keep Track of Your Blood Pressure log (http://edis.ifas.ufl.edu/fy662) can help you monitor your blood pressure between doctor visits.
