Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps blood. If this pressure rises and stays high over time, it can damage the body in many ways.
High blood pressure (HBP) is a serious condition that can lead to coronary heart disease, heart failure, stroke, kidney failure, and other health problems. High blood pressure, also called hypertension, is dangerous because it makes the heart work harder to pump blood to the body and it contributes to hardening of the arteries or atherosclerosis and the development of heart failure.

The exact causes of high blood pressure are not known. Several factors and conditions may play a role in its development, including:

  • Smoking
  • Being overweight or obese
  • Lack of physical activity
  • Too much salt in the diet
  • Too much alcohol consumption (more than 1 to 2 drinks per day)
  • Stress
  • Older age
  • Genetics
  • Family history of high blood pressure
  • Chronic kidney disease
  • Adrenal and thyroid disorders

In most reported high blood pressure cases, the underlying cause cannot be determined. This type of high blood pressure is called essential hypertension. Though essential hypertension remains somewhat mysterious, it has been linked to certain risk factors. High blood pressure tends to run in families and is more likely to affect men than women. Age and race also play a role. Essential hypertension is also greatly influenced by diet and lifestyle.

When a direct cause for high blood pressure can be identified, the condition is described as secondary hypertension. Among the known causes of secondary hypertension, kidney disease ranks highest.
