Thick legs are caused by the inconsistency of patients’ living and eating habits. Patients with thick legs are often reluctant to exercise, and the lack of exercise leads to the accumulation of large amounts of fats and fat components in the patient’s legs, resulting in thicker legs. In addition, excessive consumption of spicy and stimulating food, or food with too much fat content will lead to an increase in the fat content entering the patient’s body, lowering HDL and raising LDL, increasing the pressure on the liver to metabolize fats, thus reducing the liver’s metabolic function of fats, and free fat factors penetrating into the blood vessels and adhering to the vessel walls to form blood clots, easily leading to an increase in blood viscosity and increasing the risk of cardiovascular disease. increasing the risk of cardiovascular disease. Therefore, the patient’s thick legs are caused by improper living and eating habits, and should be adjusted with proper exercise to increase the liver’s ability to metabolize fat.
