Cholesterol is an important substance present in your body, which is fatty and waxy. It is produced by the liver from the fats that we consume through our meals. It consists of lipids, which are essential for several functions in our body. This waxy substance makes up a major part of the cells in our body and the isolate nerve fibres. Cholesterol plays a vital role in the production of sex hormones and steroid hormones. It also produces bile acids, which aid digestion and absorption of fats. These lipids, however, cannot travel through your body by itself, and so bind themselves with the lipoproteins that carry it around your body.
There are two types of cholesterol present in your body, low density lipoproteins or LDL and high density lipoproteins or HDL. The LDL is responsible for carrying the cholesterol to its destination and the HDL is responsible for carrying it back to the liver, where it is destroyed. If the levels of LDL cholesterol increase in your body, it can cause damage as the cholesterol slowly starts piling up in the arteries.
