First of all, the diet of patients with femoral head necrosis is best to be light, and there is no need to increase nutrients and supplements such as high protein, because the blood in patients with femoral head necrosis has not decreased, but the blood flow in blood vessels is blocked, which affects the blood supply of femoral head, leading to long-term insufficient blood supply and leading to femoral head necrosis. If the nutrition is too rich and the patient's activity is less, the blood lipid and blood viscosity in the patient will increase, resulting in slow blood flow and affecting the repair of the femoral head.

Secondly, patients with femoral head necrosis can eat more seafood, such as shrimp, which has the effect of tonifying kidney and promoting bone formation, and drink less. Only a small amount of wine can soften blood vessels. Some patients with osteoarthropathy will feel less pain after drinking alcohol, because alcohol inhibits the function of the central nervous system.

Finally, patients with femoral head necrosis should take more calcium supplements. For dairy products, you can choose some products with moderate calcium and phosphorus ratio, such as milk, which contains protein, lactose and other substances, and can fully absorb calcium and phosphorus. If you drink 2 cups of milk every day, it is enough to meet the needs of adults for calcium. Of course, because the elderly have lost a lot of calcium, they need more calcium. In order to better absorb calcium and phosphorus in dairy products, they should often "bask in the sun" while eating dairy products every day, and ensure that the effect will be better if they "bask in the sun" 1 hour every day.
