People with hydrocephalus are better off eating foods rich in vitamins and proteins. Hydrocephalus usually need to eat more apples, bananas, oranges, grapes, cabbage and other vitamin-rich foods, in addition to more beef, fish, chicken, milk, soy products, lean meat, eggs and other protein-rich foods. Regularly eating the above foods can provide patients with nutrition, which is more favorable for brain development. In addition, attention should be paid to limiting the intake of sodium and water, prohibiting the consumption of stimulating foods and exciting drinks. Six to 12 hours after hydrocephalus surgery, if there is no nausea, vomiting or choking, a small amount of liquid food can be fed, and then gradually return to normal diet from semi-fluid food, which can be high-calorie, high-vitamin, easy to digest, high-quality and low-protein, and avoiding hard and spicy stimulating food.
