Patients with intestinal obstruction are required to abstain from water during an attack, that is, all food is prohibited. Daily recommendations prohibit spicy and irritating food, greasy food and excessive eating. 1. Spicy stimulating food: such as chili, raw onion, raw garlic, etc., is likely to stimulate the gastrointestinal mucosa, resulting in intestinal mucosal edema, intestinal peristalsis will be weakened, which will easily lead to intestinal obstruction attacks. 2. Greasy food: for example, fatty meat, fried food, etc. may increase the burden on the gastrointestinal tract, which is not conducive to the recovery of intestinal function, and it is also easy to cause constipation, which may lead to the aggravation of intestinal obstruction. It is also not recommended to consume foods that are not easy to digest, such as rice cakes. 3. Eating too much: patients with intestinal obstruction should try to have small and frequent meals to avoid eating too much. 4. Avoid drinking alcohol: Drinking alcohol also tends to cause gastrointestinal dysfunction, which can easily lead to the attack of intestinal obstruction, so it is recommended to avoid drinking alcohol. There are many reasons for intestinal obstruction, so you should go to the hospital in time to find out the reason and then treat it.
