Why is Cholesterol Bad?
High cholesterol is bad because it increases the risk of heart disease. While your body needs cholesterol to build healthy cells, high levels lead to problems.
Excess cholesterol, specifically the "bad" cholesterol (LDL), contributes to the formation of plaque buildup within your arteries. This plaque narrows the arteries, reducing blood flow to vital organs like the heart and brain. The reduced blood flow can lead to serious consequences.
- Heart Disease: Plaque buildup in the coronary arteries (arteries supplying the heart) can cause angina (chest pain), heart attacks, and other heart-related issues. Mayo Clinic and Cleveland Clinic confirm this link.
- Stroke: Similarly, plaque buildup in arteries leading to the brain can restrict blood flow, increasing stroke risk. This is emphasized by Johns Hopkins Medicine and the CDC.
- Other Problems: High cholesterol can contribute to other health problems.
The Role of "Good" and "Bad" Cholesterol
It's crucial to understand that there are different types of cholesterol:
- LDL (Low-Density Lipoprotein): This is the "bad" cholesterol. High levels contribute to plaque formation and increase heart disease risk. Lowering LDL levels is key to improving cardiovascular health, as noted by MedlinePlus and WebMD.
- HDL (High-Density Lipoprotein): This is the "good" cholesterol. HDL helps remove cholesterol from the arteries, reducing the risk of plaque buildup. Maintaining healthy HDL levels is beneficial for heart health, as explained by the American Heart Association.
In summary, while your body requires cholesterol for essential functions, excessive LDL cholesterol poses a significant threat to your cardiovascular health.
