What does a blood pressure reading of 156 over 99 mean?

A blood pressure reading of 156 over 99 means that the systolic blood pressure (the top number) is 156 millimeters of mercury (mm Hg) and the diastolic blood pressure (the bottom number) is 99 mm Hg. This reading is considered to be high blood pressure, or hypertension. Normal blood pressure is defined as a blood pressure below 120 over 80 mm Hg.

Hypertension is a serious health condition that can increase the risk of developing heart disease, heart attack, stroke, kidney disease, and vision loss. It can also lead to an enlarged heart and heart failure.

There are many things that can cause high blood pressure, including:

- Family history of high blood pressure

- Obesity

- Physical inactivity

- Smoking

- Alcohol consumption

- High cholesterol

- Diabetes

If you have a blood pressure reading of 156 over 99 or higher, it is important to see a doctor to confirm your blood pressure reading and determine if you have high blood pressure. If you do have high blood pressure, your doctor will recommend a treatment plan to help lower your blood pressure and reduce your risk of developing serious health complications.
