LDL cholesterol level refers to the measure of low-density lipoprotein (LDL) cholesterol in the bloodstream. LDL cholesterol is commonly known as "bad" cholesterol because it contributes to the buildup of plaque in the arteries, leading to atherosclerosis and an increased risk of heart disease and stroke.
Cholesterol is a waxy, fat-like substance crucial for various bodily functions. It is transported in the blood by lipoproteins, which can be classified into different types based on their density. LDL cholesterol is a type of lipoprotein that carries cholesterol from the liver to other parts of the body, depositing it in different tissues when levels are elevated.
Measuring LDL cholesterol levels is vital in assessing a person's risk for cardiovascular disease. A higher LDL cholesterol level indicates an increased risk, whereas lower levels are generally considered healthier.
Ideally, LDL cholesterol levels should be maintained within a healthy range. The American Heart Association recommends that LDL cholesterol levels be below 100 mg/dL (2.6 mmol/L) for individuals at high risk or those who already have heart disease. However, the target levels may vary based on an individual's overall health, age, and existing medical conditions.
Ultimately, monitoring and managing LDL cholesterol levels through lifestyle changes, such as adopting a healthy diet, engaging in regular physical activity, and sometimes using medication when necessary, are crucial in reducing the risk of cardiovascular disease and promoting overall heart health.
