What causes high cholesterol?

[Rasel Ali (IT)]

As a doctor of medicine, I can provide you with a detailed answer on what causes high cholesterol. Cholesterol is a fatty substance found in the blood that is necessary for various bodily functions, such as the production of hormones and the formation of cell membranes. However, when cholesterol levels become too high, it can lead to health problems, particularly cardiovascular disease.

There are two main types of cholesterol: low-density lipoprotein (LDL) and high-density lipoprotein (HDL). LDL cholesterol is often referred to as "bad" cholesterol because it tends to accumulate in the arteries, forming plaques that can restrict blood flow. HDL cholesterol, on the other hand, is considered "good" cholesterol as it helps remove excess cholesterol from the bloodstream and prevents plaque buildup.



Several factors contribute to high cholesterol levels:

Diet: Consuming foods high in saturated and trans fats can increase LDL cholesterol levels. These unhealthy fats are commonly found in red meat, full-fat dairy products, fried foods, and processed snacks. A diet rich in fruits, vegetables, whole grains, and lean proteins, on the other hand, can help maintain healthy cholesterol levels.
Obesity: Being overweight or obese can raise LDL cholesterol levels and lower HDL cholesterol levels. Excess body fat, particularly around the waist, can lead to increased cholesterol production in the liver.
Lack of physical activity: Regular exercise has been shown to increase HDL cholesterol levels and improve overall cardiovascular health. Leading a sedentary lifestyle can contribute to higher LDL cholesterol levels.
Smoking: Smoking damages blood vessels, lowers HDL cholesterol, and increases LDL cholesterol. It also increases the risk of other cardiovascular diseases, making it a significant risk factor for high cholesterol.
Genetics: In some cases, high cholesterol levels can be inherited. Familial hypercholesterolemia is a genetic condition that causes very high LDL cholesterol levels and increases the risk of early heart disease.
Age and gender: Cholesterol levels tend to rise with age, particularly in women after menopause. Prior to menopause, estrogen helps maintain higher levels of HDL cholesterol. After menopause, however, HDL cholesterol levels may decrease, contributing to increased overall cholesterol levels.
