Diarrhea after gallstone surgery can usually eat light and easy to digest food, food rich in high quality protein, vegetables and fresh fruits and other foods. 1. Light and easy-to-digest food: Due to the dysfunction of the gallbladder after the operation, which leads to the imbalance of intestinal flora, it is recommended to eat some light and easy-to-digest food, such as rice soup, egg custard, soft noodles and other food, which is easy to be digested, and you can also drink some warm boiled water to avoid the dehydration of your body. 2. Foods rich in high quality protein: to meet the needs of the body’s metabolism, you can increase the amount of food rich in high quality protein, such as lean meat, eggs, etc., pay attention to small meals to avoid indigestion. 3. Vegetables and fresh fruits: vegetables and fruits are rich in vitamins and dietary fiber, which can provide the body with what it needs, but also relieve the symptoms of diarrhea. If diarrhea persists without relief, it is recommended to go to the hospital in time, under the guidance of the doctor to avoid delaying the condition and causing other damages.
