After femoral head replacement, the patient needs to be bedridden for a period of time. There are dietary requirements during this period, such as the patient should not eat too greasy food, as eating too greasy food is not easy to digest and will increase the burden on the gastrointestinal tract. Dairy products are also not allowed because they tend to cause abdominal distension, which makes it more difficult for the patient to be bedridden. Patients should eat plenty of fresh vegetables and fruits to help with bowel movements in bed. Patients with femoral head replacement should drink as much water as possible. Drinking more water will promote blood thinning and prevent thrombosis. There are other requirements, such as patients with diabetes or cerebral infarction should have a low salt and low fat diet and control sugar intake.
