Introduction
High cholesterol is one of the most common health conditions worldwide and a major risk factor for heart disease and stroke. Cholesterol is a waxy, fat-like substance that is naturally produced by the liver and is also obtained from certain foods. While the body needs cholesterol to build healthy cells, produce hormones, vitamin D, and digestive substances, having too much cholesterol in the blood can be harmful.
When cholesterol levels become too high, fatty deposits can build up inside the arteries. Over time, these deposits can narrow the arteries, reducing blood flow and increasing the risk of serious health problems such as heart attack and stroke. High cholesterol often develops without noticeable symptoms, which is why it is commonly called a “silent condition.”
What is Cholesterol?
Cholesterol is a waxy, fat-like substance found in every cell of the body. It is essential for many important functions, including:
- Building healthy cell membranes
- Producing hormones
- Making vitamin D
- Helping the body digest fats
Although cholesterol is necessary for good health, too much cholesterol can increase the risk of cardiovascular diseases.
Types of Cholesterol
1. LDL (Low-Density Lipoprotein): LDL is known as bad cholesterol. High LDL levels can lead to plaque buildup inside arteries, increasing the risk of heart disease and stroke.
2. HDL (High-Density Lipoprotein): HDL is called good cholesterol because it helps remove excess cholesterol from the bloodstream and carries it back to the liver.
3. VLDL (Very Low-Density Lipoprotein): VLDL mainly transports triglycerides in the blood. High VLDL levels may contribute to artery blockage.
4. Triglycerides: Triglycerides are a type of fat stored for energy. High triglyceride levels may increase the risk of heart disease, especially when combined with high LDL and low HDL.
