Thickening of the buttocks and thighs is commonly caused by the following reasons: First, developmental reasons: Patients have an obvious family history of hereditary diseases, and patients will have thickening of the buttocks and thighs compared to normal people, but there are no obvious clinical symptoms and no special treatment is needed. Second, excessive fat accumulation: If the patient is obese, fat tends to accumulate to the hips and thighs, making the hips and thighs thicker than the normal population. At this time, the intake of carbohydrates should be controlled and aerobic training should be increased to consume fat and reduce the fat in the hips and thighs, so that the appearance of the hips and thighs can be restored to a normal level. Third, acquired exercise: such as weight bearing, deep squatting, and long-term squatting work can lead to thickening of the hip and thigh muscles. Patients have no obvious clinical symptoms, while the muscle strength of the buttocks and thighs will be significantly increased. Therefore, the appearance of thickening of the buttocks and thighs does not normally require special treatment, and if it is necessary to reduce weight, diet control and moderate exercise can be used.
