During the recovery period after gastric perforation surgery, you can eat some easy-to-absorb food, protein-rich and easy-to-digest food. 1. Easy-to-absorb food: patients are weak after the operation, they can drink some easy-to-absorb food, such as noodles, rice porridge, etc., which can help the repair of gastric mucosa. 2. Protein-rich food: patients need to supplement protein to promote wound healing after surgery. Egg custard, milk, chicken soup, fish soup and other foods can be consumed to supplement high-quality protein. Milk can also neutralize the effect of gastric acid and promote the recovery of gastric mucosa. Note that you should drink warm milk. 3. Easy to digest: patients with gastric perforation should consume easy-to-digest food after surgery, so as not to affect the recovery of gastrointestinal peristalsis. Therefore, you can eat some fresh vegetables and fruits, such as green vegetables, cabbage, banana, apple and so on. It should be noted that gastric perforation patients should not overeat after surgery, do not eat cold and stimulating food, and eat a light diet. If there is any discomfort, repeat the examination in time.
