In general, thin people may also experience high cholesterol levels.

Genetic factors play an important role in cholesterol levels. Some people are born with higher cholesterol levels, which may be related to their genes. Therefore, even if patients maintain a healthy weight or are underweight, they may still have high cholesterol if they carry the associated genetic genes.

At the same time, unhealthy lifestyle habits are also an important cause of high cholesterol. If thin individuals consistently consume high-fat, high-cholesterol foods, lack physical activity, or have不良 habits such as smoking and excessive alcohol consumption, it may lead to elevated cholesterol levels. Additionally, certain health conditions, such as hypothyroidism, diabetes, and kidney disease, can also lead to high cholesterol, and these conditions are not necessarily related to body weight.

Thin individuals should also regularly check their cholesterol levels and maintain good lifestyle habits, such as balanced nutrition, regular exercise, quitting smoking, and limiting alcohol consumption, which are beneficial for maintaining cardiovascular health.
