What is Blood Pressure?

The function of the cardiovascular system is to deliver nutrition and oxygen via blood to the body. To get blood to circulate throughout the entire body from head to toe, it requires to be pumped at an adequate pressure, measured as blood pressure. As a consequence of ageing or unhealthy lifestyle, and conditions such as diabetes, the blood vessels that carry blood become stiffer and less elastic thus increasing the pressure within causing high blood pressure.

Pressures of 120/80 mmHg are considered normal. Anything more than 140/90 mmHg are termed as high blood pressure or hypertension. Values in between are considered to be pre-hypertension.

Sustained high blood pressure results in damage to the lining of blood vessels leading to deposition of cholesterol and block formation. This sets the stage to develop heart attacks, heart failure, stroke and gangrene of the limbs.

Ask Dr Rao

How often should BP be checked?

Once every six months is sufficient to detect for blood pressure. Checking every day or once a week is not advisable as this would increase anxiety.

Can we stop BP medicines once pressure is under control?

Medication for blood pressure is usually prescribed lifelong. The pressure becomes normal as a result of the medication and a sudden discontinuation may result in life threatening rebound hypertension.

Is a home monitor useful?

Electronic home BP monitors, though are not very accurate, can provide a trend of blood pressure and are useful.

How important is stress?

Stress causes the blood vessels to narrow resulting in higher blood pressure. It is as bad as smoking and diabetes, and causes damage to the blood vessels.
