How high blood cholesterol levels increase the risk of heart diseases?
Cholesterol is transported via blood to liver and other parts of the body. These fat droplets can pass through easily from large arteries; however arteries supplying blood to heart have narrow caliber and these fat droplets get stuck in the lumen of these arteries. With time, the lumen or opening of the blood vessels get progressively narrowed. The narrowing of the blood veseel is a slow process and nothing seems evident in the beginning. But progressively it gets worse and is manifested with a gradual decline in the functional activity of a person. For example, after vigorous physical activity, if you feel pain in the chest, it’s an early sign of beginning stages of heart disease.
After the small fat droplets get stuck to the wall of blood vessels or arteries of heart, it continues to get bigger due to accumulation of cellular debris and more fat droplets until the artery gets fully blocked at some point leading to a full blown heart disease. When heart disease due to arterial problem develops, the overall quality of life is greatly affected as even mild physical activity or even no activity may elicit chest pain, increased heart rate or even unconsciousness. If left untreated, it can result in heart attack and may even lead to death of the person.
What can you do to minimize the risk of heart diseases?
If you have positive family history of heart diseases, high blood cholesterol or diabetes, you must exceptionally control your blood cholesterol levels. You must keep your total blood cholesterol level under 180 mg/dL. Without the risk factors the normal range is 200mg/dL. According to latest recommendation, every man and woman must get their blood cholesterol checked on yearly basis after the age of 45 years.
