Cholesterol is a waxy, fat-like substance that is produced by our liver as it is needed by our body to carry out some important functions. There are basically two types of cholesterol: bad and good. These cholesterol travel through the bloodstream with lipoproteins, soluble proteins that transport fats through the body. When the quantity of bad cholesterol increases in the blood, it starts depositing in tissues and blood vessels and the real trouble begins. With medication and positive dietary changes, the level of bad cholesterol in the body can be easily managed. A common question that remains is how much time does it take to lower the level of bad cholesterol in the body.
