Hypertension is also known as ‘high blood pressure’. Normally, blood pressure increases beyond the normal limit when a person does any physical activity such as exercise, or sports, etc. This rise in pressure becomes normal after some time. If the pressure remains high for a long time, the condition is called hypertension and needs treatment.
The heart is a muscular organ about the size of a closed fist that functions as our body’s circulatory pump. When the blood flows with high pressure due to hypertension across the blood vessels, it causes some serious complications. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation and then pumps this oxygenated blood into the arteries. Learn more about your heart.
Hypertension, (also known as high blood pressure), is often a "silent disease" because the signs do not appear in the beginning in most cases. You might not even know that you have it. But, the increased blood pressure continues to damage your body and by the time you diagnose it, it is already late.
The exact cause of hypertension is not understood completely. Scientists believe that there are various mechanisms that can be considered to cause hypertension. These include increased stress level in the blood vessel walls, increased blood volume, and harder blood vessels. The main causes among these mechanisms are not understood fully but there are various risk factors that may trigger hypertension in a person.
When the blood flows with high pressure across the blood vessels, it causes some serious complications. Since hypertension is the ‘silent killer’, it does not show any complication at an early stage. High blood pressure over time can disturb functions of several organs such as kidneys, heart, eyes, etc.
