Alcohol will inhibit the normal metabolism of bone cells, inhibit osteoblasts, and will prevent the absorption and utilization of calcium and magnesium, so habitual long-term drinking will lead to osteoporosis. As we all know, alcoholism can trigger femoral head necrosis. If alcohol is consumed for a long time, it will cause an increase in fat cells in the femoral head and increase in size, resulting in higher pressure in the narrow space within the femoral head and a decrease in blood supply, and over time, the femoral head will become necrotic due to ischemia. Things are not absolute, moderate drinking can promote blood circulation, but no matter what age you should try to drink less, not to mention the habit of alcoholism, excessive drinking will only hurt your body, but also cause the disease of femoral head necrosis.
