It is not allowed to eat bananas during diarrhea. When you have diarrhea, you should try to eat foods that are slightly hot and have an anti-diarrheal effect, such as pomegranate and steamed apples, in order to promote the recovery of gastrointestinal function and reduce the symptoms of diarrhea. Banana itself is a cold fruit, so eating cold food during diarrhea will lead to a stress reaction in the gastrointestinal system and make diarrhea more serious. Bananas contain a lot of water-soluble dietary fiber and also have a laxative effect. Eating bananas can promote constipation when constipated, but eating bananas during diarrhea can aggravate diarrhea symptoms. During diarrhea, you should take proper rest and keep your abdomen warm. If necessary, you can use montelukast, enteritis and other medications to treat it.
