High Blood Pressure

High blood pressure increases your chance (or risk) for getting heart disease and/or kidney disease, and for having a stroke. It is especially dangerous because it often has no warning signs or symptoms. Regardless of race, age, or gender, anyone can develop high blood pressure. It is estimated that one in every four American adults has high blood pressure. Once high blood pressure develops, it usually lasts a lifetime. You can prevent and control high blood pressure by taking action.

Do You Have High Blood Pressure?

You can find out if you have high blood pressure by having your blood pressure checked regularly. Most doctors will diagnose a person with high blood pressure on the basis of two or more readings, taken on several occasions. A consistent blood pressure reading of 140/90 mmHg or higher is considered high blood pressure, another term for hypertension.

Some people experience high blood pressure only when they visit the doctor's office. This condition is called "white-coat hypertension." If your doctor suspects this, you may be asked to monitor your blood pressure at home or asked to wear a device called an ambulatory blood pressure monitor. This device is usually worn for 24 hours and can take blood pressure every 30 minutes. In this section you will learn more about diagnosing high blood pressure.

Categories for Blood Pressure Levels in Adults
(Ages 18 Years and Older)

Blood Pressure Level (mmHg)
Category Systolic   Diastolic
Normal < 120 and < 80
Prehypertension 120-139 or 80-89
High Blood Pressure
Stage 1 Hypertension 140-159 or 90-99
Stage 2 Hypertension greater than or equal to 160 or greater than or equal to 100

When systolic and diastolic blood pressures fall into different categories, the higher category should be used to classify blood pressure level. For example, 160/80 mmHg would be stage 2 hypertension (high blood pressure).

Taking Action.

You can take steps to prevent high blood pressure by adopting a healthy lifestyle. These steps include:

  • Maintaining a healthy weight;
  • Being physically active;
  • Following a healthy eating plan, that emphasizes fruits, vegetables, and lowfat dairy foods;
  • Choosing and preparing foods with less salt and sodium; and,
  • If you drink alcoholic beverages, drinking in moderation.

It is important to take steps to keep your blood pressure under control. The treatment goal is blood pressure below 140/90 and lower for people with other conditions, such as diabetes and kidney disease. Adopting healthy lifestyle habits is an effective first step in both preventing and controlling high blood pressure. If lifestyle changes alone are not effective in keeping your pressure controlled, it may be necessary to add blood pressure medications. Talk to your doctor about your blood pressure today.
