Blood pressure: It is the measurement of the force that our heart uses to pump blood to all parts of the body. Hypertension is a chronic condition when blood pressure is too high. This condition can lead to hardened arteries (blood vessels), decreasing the blood and oxygen flow to the heart. Raised blood pressure can cause chest pain (angina) and heart attack (when blood supply to the heart is blocked). Additionally, high blood pressure also causes brain damage (stroke) and kidney failure. High blood pressure can be diagnosed with the help of a blood pressure monitor or sphygmomanometer. Systolic pressure is the pressure when the heart pumps blood out. On the other hand, diastolic pressure is when your heart is at the resting stage between heartbeats. If your blood pressure is 140/90 mm of Hg, it means the systolic pressure is 140 mm of Hg, and diastolic pressure is 90 mm of Hg. Ideal blood pressure should be between 90/60 mm of Hg and 120/80 mm of Hg.
