little bit on HYPERTENSION







Hypertension is the term used to describe high blood pressure.
Blood pressure is a measurement of the force against the walls of your arteries as the heart pumps blood through the body.
Blood pressure readings are measured in millimeters of mercury (mmHg) and usually given as two numbers -- for example, 120 over 80 (written as 120/80 mmHg). One or both of these numbers can be too high.
The top number is your systolic pressure.
  • It is considered high if it is over 140 most of the time.
  • It is considered normal if it is below 120 most of the time.

The bottom number is your diastolic pressure.
  • It is considered high if it is over 90 most of the time.
  • It is considered normal if it is below 80 most of the time.
    Pre-hypertension
    may be considered when your:

    • Top number (systolic blood pressure) is between 120 and 139 most of the time, or
    • Bottom number (diastolic blood pressure) is between 80 and 89 moST of the time



      Many factors can affect blood pressure, including:
      • How much water and salt you have in your body
      • The condition of your kidneys, nervous system, or blood vessels
      • The levels of different body hormones




      You have a higher risk of high blood pressure if you:
      • Are African American
      • Are obese
      • Are often stressed or anxious
      • Eat too much salt in your diet
      • Have a family history of high blood pressure
      • Have diabetes
      • Smoke



      High blood pressure that is caused by another medical condition or medication is called secondary hypertension. Secondary hypertension may be due to:
      • Endocrine disorders, such as adrenal tumors (pheochromocytoma, aldosteronism), thyroid disorders, and Cushing syndrome
      • Medications
        • Appetite suppressants
        • Birth control pills
        • Certain cold medications
        • Corticosteroids
        • Migraine medications
      • Renal artery stenosis

        Signs and tests

        If you monitor your blood pressure at home, you may be asked the following questions:
        • What was your most recent blood pressure reading?
        • What was the previous blood pressure reading?
        • What is the average systolic (top number) and diastolic (bottom number) reading?
        • Has your blood pressure increased recently?
          These tests may include:

          PREVENTION

        • Eat a heart-healthy diet, including potassium and fiber, and drink plenty of water.
        • Exercise regularly -- at least 30 minutes a day.
        • If you smoke, quit -- find a program that will help you stop.
        • Limit how much alcohol you drink -- 1 drink a day for women, 2 a day for men.
        • Limit the amount of sodium (salt) you eat -- aim for less than 1,500 mg per day.
        • Reduce stress -- try to avoid things that cause stress for you. You can also try meditation or yoga.
        • Stay at a healthy body weight -- find a weight-loss program to help you, if you need it.
