What is cholesterol?

Cholesterol is a fatty, wax-like substance found in every cell of the body. It is essential for building cell membranes, producing hormones such as estrogen and testosterone, and creating vitamin D. However, excessive cholesterol in the blood, especially low-density lipoprotein (LDL or “bad” cholesterol), can accumulate in the arteries, increasing the risk of heart disease and stroke. High-density lipoprotein (HDL or “good” cholesterol) helps remove excess cholesterol from the bloodstream. Cholesterol levels are influenced by diet, genetics, and lifestyle. Regular exercise, balanced nutrition, and reduced intake of saturated fats can help maintain healthy cholesterol levels.
