High Blood Pressure


High blood pressure is abnormally high blood pressure with no known cause. Blood pressure measurements are read as two numbers. The higher number is called the systolic pressure . The lower number is called the diastolic pressure. Normal systolic pressure is 120 or less, and normal diastolic blood pressure is 80 or less.

High blood pressure is defined as systolic pressure greater than 140 and/or diastolic pressure greater than 90. People with systolic blood pressures between 120 and 139, or diastolic pressures of 80 to 89 are considered "prehypertensive" and need medical monitoring and lifestyle changes.

High blood pressure puts stress on the heart, lungs, brain, kidneys, and blood vessels. Over time, high blood pressure can damage these organs and tissues.

Risk Factors

A risk factor is something that increases your chance of getting a disease or condition. Risk factors for high blood pressure include:

  • Sex : - Male - Postmenopausal female
  • Race: Black
  • Age: Middle-aged and older
  • Overweight
  • Heavy drinking of alcohol
  • Smoking
  • Use of oral contraceptives (birth control pills)
  • Sedentary lifestyle
  • Family history
  • Kidney disease
  • Diabetes
  • High-fat, high-salt diet
  • Emotional stress



High blood pressure usually does not cause symptoms. Your organs and tissues can be damaged by high blood pressure without you feeling any symptoms. Occasionally, if blood pressure reaches extreme levels, you may experience the following symptoms:

  • Headache
  • Blurry or double vision
  • Abdominal pain
  • Chest pain
  • Shortness of breath
  • Dizziness



High blood pressure is often diagnosed during a visit to the doctor. Blood pressure is measured using a cuff around the arm and a device called a sphygmomanometer. If your blood pressure reading is high, you'll be asked to come back for repeat blood pressure checks. If you have two or more visits with readings over 140/90, you will be diagnosed with high blood pressure.

Tests to make sure your high blood pressure is not caused by another medical condition and that it has not already caused complications include:

  • Blood tests
  • Urine tests
  • Chest x-rays – a test that uses radiation to take a picture of structures inside the body
  • Electrocardiogram (ECG, EKG) – a test that records the heart's activity by measuring electrical currents through the heart muscle


Treatment Overview

Lifestyle Changes
  • Begin a safe exercise program based on the advice of your doctor. In addition, try to add physical activity into your daily life.

  • Consider counseling, stress reduction exercises, and meditation to decrease the stress in your life.



Types of medications to lower blood pressure include:

  • Diuretics
  • Beta blockers
  • Angiotensin converting enzyme inhibitors (ACE inhibitors)
  • Calcium channel blockers
  • Alpha blockers
  • Alpha-beta blockers
  • Nervous system inhibitors
  • Vasodilators


Note: Untreated high blood pressure can lead to:

  • Heart disease
  • Heart attack
  • Stroke
  • Kidney damage






To reduce your chance of developing high blood pressure:
