Hypertension:
High blood pressure, also called hypertension, is when the pressure of blood in the arteries is higher than normal. When someone has hypertension, the arteries are under excessive pressure, which can cause extra strain and stress on the walls of the blood vessels. Because of this higher pressure, the heart has to work harder to pump blood throughout the body. Over time, this extra effort can lead to damage in the heart and blood vessels.
- Both systolic pressure (pressure during the heartbeat) and diastolic pressure (pressure when the heart relaxes) are elevated in people with hypertension.
- Hypertension is often called the "silent killer" because it typically does not show clear symptoms, but it can cause serious health issues like heart attack, stroke, and kidney problems if not managed.
- Managing hypertension is important, and this can be done through lifestyle changes, medication, regular exercise, a healthy diet, and avoiding excessive salt intake.
- Regular blood pressure monitoring helps to detect and manage hypertension early, preventing potential complications.
Type | Systolic Pressure | Diastolic Pressure |
---|---|---|
Normal Blood Pressure | 90 - 119 mm | 60 - 79 mm |
Primary Hypertension | 120 - 139 mm | 80 - 89 mm |
Hypertension Stage-I | 140 - 159 mm | 90 - 99 mm |
Hypertension Stage-II | > 160 mm | > 100 mm |
