 Cholesterol: Types, Causes, Symptoms, Prevention, and Treatment

What is Cholesterol?

Cholesterol is a waxy, fatty substance that is naturally produced by the liver and also enters the body through certain foods. It plays an essential role in hormone production, digestion, cell structure, and maintaining energy balance. However, when cholesterol levels rise above the normal range, it can negatively affect the heart, brain, and blood vessels.

Sources of Cholesterol in the Body

• 80% is produced by the liver (genetics also play a significant role).

• 20% comes from dietary sources such as meat, egg yolk, butter, liver, and fried foods.

Types of Cholesterol

1. HDL (High-Density Lipoprotein – Good Cholesterol):

   • Helps remove cholesterol from blood vessels.

   • Carries it back to the liver for elimination.

   • Protects against heart disease.

2. LDL (Low-Density Lipoprotein – Bad Cholesterol):

   • Builds up inside blood vessels.

   • Forms plaques that narrow arteries.

   • Increases the risk of heart disease and stroke.

3. Triglycerides:

   • Stores excess energy in the form of fat.

   • Consistently high levels raise the risk of heart and metabolic problems.
