Occasional drinking is not recommended for necrosis of the femoral head. Because drinking a lot of alcohol for a long time can cause the metabolism of fat in the liver to be disturbed, which can lead to the formation of small blood clots in the blood vessels, thus causing the blood circulation in the femoral head area to be impaired and ischemia, and then cause necrosis of the femoral head. You should maintain good indoor air, keep suitable temperature and humidity, and ventilate frequently. Diet should be light, rich in vitamins and high in calcium. Avoid alcohol, greasy, cold and irritating food. Patients with necrosis of the femoral head should go to the hospital in time and follow the doctor’s instructions for treatment to avoid delaying the condition.
