Cholesterol has both positive and negative effects. It is a necessary substance for the body at regular levels. However, if blood concentrations reach too high, it becomes a silent threat, putting patients at risk of a heart attack. Cholesterol is found in every cell of the body and plays a crucial role in digestion, hormone production, and vitamin D production. It is produced by the body, but it is also consumed in food. It has a waxy, fat-like look. Cholesterol is classified into two types: - LDL (low-density lipoproteins), sometimes known as "bad" cholesterol - HDL (high-density lipoproteins), also known as "good" cholesterol
