in Glossary

Cholesterol is a waxy, fat-like substance that is found in all the cells of your body. It plays a vital role in various bodily functions, including:

  • Building cell membranes: Cholesterol is a key component of the outer layer of cells.
  • Producing hormones: It is essential for the production of hormones like estrogen, testosterone, and cortisol.
  • Aiding digestion: Cholesterol helps the liver produce bile acids, which are necessary for digesting fats.
  • Synthesizing vitamin D: It is involved in the production of vitamin D when your skin is exposed to sunlight.

Types of Cholesterol

Cholesterol travels through the bloodstream in particles called lipoproteins, which are made up of fat and proteins. There are two main types of lipoproteins that carry cholesterol throughout your body:

  1. Low-Density Lipoprotein (LDL): Often referred to as “bad” cholesterol, LDL can build up on the walls of your arteries, forming plaques. This can lead to blockages, which increase the risk of heart disease and stroke.
  2. High-Density Lipoprotein (HDL): Known as “good” cholesterol, HDL helps remove excess cholesterol from the bloodstream by transporting it back to the liver, where it’s broken down and removed from the body.

Health Implications

  • High cholesterol levels, particularly high LDL cholesterol, can lead to the development of atherosclerosis (the hardening and narrowing of the arteries), which increases the risk of cardiovascular diseases, such as heart attacks and strokes.
  • Low HDL cholesterol levels may also raise the risk of heart disease, as the body may not be as effective in clearing excess cholesterol from the bloodstream.

Managing Cholesterol

To maintain healthy cholesterol levels, it’s important to:

  • Eat a balanced diet low in saturated fats and trans fats.
  • Increase your intake of fiber-rich foods like fruits, vegetables, and whole grains.
  • Exercise regularly.
  • Avoid smoking and limit alcohol intake.
  • In some cases, medications like statins may be prescribed by a doctor to help lower cholesterol levels.

Regular check-ups and blood tests, known as lipid panels, can help monitor cholesterol levels and assess your risk for heart disease.
