Because gastrointestinal activity temporarily stopped after intestinal surgery. Drinking water entering the gastrointestinal tract cannot drop, and it accumulates in the stomach, causing bloating. So you can't eat or drink after the operation. You can't eat until your gastrointestinal activity is restored.

During the recovery period, attention should be paid to maintaining proper physical activity and reducing the possibility of intestinal adhesion.

After 5-6 days, you can change to a semi-liquid diet with less residue. During this period, the liquid should be light, nutritious and warm to avoid bringing coarse food residues into the liquid. When switching to a semi-liquid diet with less residue, avoid chicken, ham and soup of various vegetables. Even if these foods are not cooked well, they must wait until 10 day after the operation.
