What foods are appropriate to eat when experiencing both diarrhea and vomiting?

Internal Medicine

Diarrhea and vomiting can quickly leave you dehydrated and depleted, so choosing the right foods matters. Green (unripe) bananas are rich in resistant starch, which helps firm stools and restore gut function. Honey may soothe the stomach, replenish energy, and offer mild antimicrobial support. Together, they can help ease symptoms while your body recovers.

That said, diarrhea and vomiting can stem from many causes — from a simple stomach bug to food poisoning, infections, or something more serious. Guessing wastes time and can delay proper care. Take a free, instant, online symptom check to better understand what may be causing your symptoms and confidently decide your next steps.

Explanation

When you have both diarrhea and vomiting, it is important to eat foods that can help settle your stomach and intestines. According to the studies provided, green bananas are beneficial. They contain pectin, a type of fiber that can help firm up stools and reduce diarrhea.

Another helpful food is honey. It has been shown to be effective in treating gastroenteritis, especially in children (however honey is not reommended in children less than 1 year of age). Honey can help soothe the stomach and provide some energy when you are not feeling well.

It is important to introduce these foods slowly and in small amounts. Make sure to also drink plenty of fluids to stay hydrated, as both vomiting and diarrhea can lead to dehydration.
