Doctors often prescribe statins for people with high cholesterol to lower their total cholesterol and reduce their risk of a heart attack or stroke. They believe that having too much cholesterol in your blood increases your risk of heart attacks and strokes. Statins block the pathway of cholesterol synthesis in your body. So the body became unable to synthesize cholesterol through his own system. But cholesterol produced by us is important for function of brain, synthesis of androgenic hormones, synthesis of Vitamin D etc. Low cholesterol is responsible for memory loss and patient often face impotency. More than 50% of patients of heart disease have normal cholesterol and atleast half of the people with elevated cholesterol doesn’t not have any heart disease. Their is a player in cholesterol called LPA which can make difference but most of the physicians do not have much knowledge about it and aren’t even measuring it.
