HIGH CHOLESTEROL Meaning and
Definition
-
High cholesterol is a medical condition characterized by abnormally elevated levels of cholesterol in the blood. Cholesterol is a vital substance produced naturally by the liver and also obtained through certain foods. It plays an essential role in the body by helping to build cell membranes, produce hormones, and aid in the digestion of dietary fats. However, when levels of cholesterol exceed the normal range, it can lead to various health problems.
The term "high cholesterol" typically refers to high levels of low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol. LDL cholesterol can accumulate in the arteries, forming fatty deposits known as plaques that restrict blood flow and increase the risk of heart disease, stroke, and other cardiovascular disorders. High cholesterol may also include elevated levels of triglycerides, another type of fat found in the blood, which can further increase the risk of heart disease.
High cholesterol often goes unnoticed as it generally does not cause any symptoms itself. It is commonly diagnosed through blood tests that measure the levels of different types of cholesterol. Lifestyle factors such as a diet high in saturated and trans fats, lack of physical activity, obesity, and smoking contribute to high cholesterol levels. Additionally, genetic factors may predispose individuals to high cholesterol.
Treatment for high cholesterol generally involves lifestyle modifications such as adopting a healthy diet and exercise regimen, losing weight, quitting smoking, and limiting alcohol consumption. In some cases, medication may be prescribed to help lower cholesterol levels. Regular monitoring of cholesterol levels is recommended to assess the effectiveness of treatment and reduce the risk of complications associated with high cholesterol.
Etymology of HIGH CHOLESTEROL

The term "high cholesterol" refers to elevated levels of cholesterol in the blood. The word "high" indicates an excessive or elevated state, while "cholesterol" refers to the specific substance being measured.
