High blood pressure is known as the silent killer, because you can have it for a long time and yet be unawares about it as there may not be any symptoms at all. In primary hypertension the cause for this is not known, but in secondary hypertension the cause can be diagnosed. Once you know the cause, it is simpler to treat the cause and bring the blood pressure to normal. However, if the cause is not known, then precautionary measures have to be taken to keep it under control.
Blood pressure is the pressure that is put on the arteries to pump the blood from the heart to the arteries. The blood is first pumped to the larger arteries and then to the smaller ones that are called arterioles which in turn taper to finer vessels called capillaries. Oxygen and nutrients are supplied to all the organs of the body by the capillaries. The circle is complete when the impure blood returns to the heart to be purified through the veins.
Causes of high blood pressure:
- Narrowing of arteries due to cholesterol or arterial sclerosis
- Problems with the kidneys
- Congenital problems with the main arteries
Precautions to take when you are hypertensive:
- Bring down your weight
- Reduce the intake of salt
- Do moderate exercise like walking or aerobics
- Give up smoking
- Have limited alcohol
- Reduce fatty foods
- Bring down the cholesterol levels
However if there are problems which can be treated with invasive methods, then you would have to undergo surgery. Once the problem is resolved the blood pressure would automatically become normal.
