Hypertension, or high blood pressure, is dangerous because it can lead to strokes, heart attacks, heart failure, or kidney disease. The goal of hypertension treatment is to lower high blood pressure and protect important organs, like the brain, heart, and kidneys from damage. High blood pressure is now classified as a systolic blood pressure greater than 130 and diastolic over 80. To prevent high blood pressure, everyone should be encouraged to make lifestyle modifications, such as eating a healthier diet, quitting smoking, and getting more exercise. Treatment with medication is recommended to lower blood pressure to less than 130/80 in people older than age 65 and those with risk factors such as diabetes and high cholesterol. Treating high blood pressure involves lifestyle changes and possibly drug therapy.
