What Causes High Blood Pressure?

High blood pressure usually develops slowly over many years. In many people, doctors cannot find one exact cause. This is called primary hypertension. It is often linked to age, family history, and lifestyle habits.

Sometimes, high blood pressure happens because of another medical condition. This is called secondary hypertension. It may be caused by kidney disease, certain hormone disorders, sleep apnea, or some medicines.

Common Causes

Several factors can increase your blood pressure over time:

 Eating too much salt

Being overweight or obese

 Lack of physical activity

 Smoking or using tobacco

 Drinking too much alcohol

 Long-term stress

Poor sleep

Many people have more than one risk factor. The more risk factors you have, the higher your chance of developing high blood pressure.
