Normal Cholesterol
The body has a system to speed up or reduce cholesterol production in accordance with dietary intake. There are two types of cholesterol. Low-density lipoprotein and high-density lipoprotein. LDL is considered bad cholesterol and HDL is good cholesterol. When the levels of LDL become high in blood, the LDL cholesterol gets deposited in blood vessel walls. Arteries become thickened or hardened (arteriosclerosis) and block the free passage of blood. This increases blood pressure and leads to cardio vascular diseases including heart attack. Another version of LDL is Lp(a). Lp(a) is a variation of LDL, which increase the risk of arteriosclerosis (thickening of blood vessels walls by deposition of fat).
