A Dangerous High: 3 Types of Hypertension

PART 1

What Are the Different Types of Hypertension?

There are three types of hypertension:

  • Primary, or essential, hypertension accounts for 90-95% of all cases and doesn’t have a specific, treatable cause. However, an unhealthy lifestyle can play a role in developing hypertension in people who have a predisposition for it.

  • Secondary hypertension is caused by an underlying condition, such as a kidney disorder or a congenital abnormality. The high blood pressure generally returns to normal when the problem is corrected.

  • Pregnancy-related hypertension may occur in women who have a predisposition to hypertension when they become pregnant.

High Blood Pressure

Also called: Benign essential hypertension, Essential hypertension, HBP, HTN, Hypertension

Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.

Your blood pressure reading uses these two numbers. Usually the systolic number comes before or above the diastolic number. A reading of

  • 119/79 or lower is normal blood pressure
  • 140/90 or higher is high blood pressure
  • Between 120 and 139 for the top number, or between 80 and 89 for the bottom number is called prehypertension. Prehypertension means you may end up with high blood pressure, unless you take steps to prevent it.

High blood pressure usually has no symptoms, but it can cause serious problems such as stroke, heart failure, heart attack and kidney failure.

You can control high blood pressure through healthy lifestyle habits and taking medicines, if needed.
