Hypertension, often known as high or increased blood pressure, is a disorder in which the blood vessels have abnormally high pressure for an extended period.

The force of blood pushing against the walls of arteries as it is pumped by the heart causes blood pressure.

The heart has to work harder to pump blood when the pressure is high.

Blood Pressure Readings

  • Normal    
systolic: less than 120 mm Hg
diastolic: less than 80 mm Hg

  • Prehypertension
systolic: 120–139 mm Hg
diastolic: 80–89 mm Hg    

  • Hypertension
systolic: 140 mm Hg or higher
diastolic: 90 mm Hg or higher

  • Kidney Impairment
It's more difficult for the kidneys to complete their work when blood capillaries in the kidneys become weaker and narrowed as a result of high blood pressure damage.

  • Heart Attack: occurs when the blood supply to the heart muscle tissue is cut off, which is frequently caused by excessive blood pressure.
  • A stroke occurs when a clot plugs a blood vessel. Strokes can be fatal because the damaged part of the brain no longer receives the necessary nutrition and oxygen, and it begins to die.
  • Vision Loss: This is known as hypertensive retinopathy, and it can result in eye haemorrhage, blurred vision, or blindness.
