When a direct cause for high blood pressure can be identified, the condition is described as secondary hypertension. Among the known causes of secondary hypertension, kidney disease ranks highest. Hypertension can also be triggered by tumors or other abnormalities that cause the adrenal glands (small glands that sit atop the kidneys) to secrete excess amounts of the hormones that elevate blood pressure. Birth control pills -- specifically those containing estrogen -- and pregnancy can boost blood pressure, as can medications that constrict blood vessels.
Aerobic exercise : Also known as “cardio,” aerobic exercise is any type of physical activity that raises your heart rate. Examples include brisk walking, jogging, running, jumping rope, and swimming. Studies show that doing 30 minutes of aerobic exercise 5 to 7 days a week can cut your risk of heart disease, lower your blood pressure, boost your HDL (good) cholesterol, and help with weight loss.
High blood pressure, also called hypertension, can damage your blood vessels, heart and kidneys. This damage can cause a heart attack, stroke or other health problems. Your blood pressure reading is based on two measurements called systolic and diastolic. The systolic (top number) and diastolic (bottom number) are written as a ratio, for example (120/80 mmHg). A reading of more than 140/90 mmHg taken at your healthcare provider’s office may indicate high blood pressure. This figure is different for people with diabetes whose blood pressure should be below 130/80 mmHg. People suffering from other illnesses will have different target normal values.

If your blood pressure is elevated, your doctor may request you have more readings over the course of a few days or weeks. A hypertension diagnosis is rarely given after just one reading. Your doctor needs to see evidence of a sustained problem. That’s because your environment can contribute to increased blood pressure, such as the stress you may feel by being at the doctor’s office. Also, blood pressure levels change throughout the day.
