Foods to eat

Foods to eat when you have diarrhea

When you have diarrhea, the foods that you eat and the foods that you avoid can be critical to helping you recover quicker. This is where BRAT foods come in.

BRAT stands for “bananas, rice, apples, toast.” These foods are bland, so they won’t aggravate the digestive system. They’re also binding, to help firm up stool. Other foods that are included in the BRAT diet include:

  • cooked cereal like cream of wheat or farina
  • soda crackers
  • applesauce and apple juice

You also need to drink plenty of liquids so that you can stay hydrated and replace the fluids that you’re losing. Drink lots of water and suck on ice chips. Other liquids that you can try include:

  • clear broths, like chicken broth or beef broth, with any grease removed
  • electrolyte-enhanced water or coconut water with vitamins or electrolytes (try to avoid ones high in sugar)
  • solutions like Pedialyte
  • weak, decaffeinated tea

After you’ve started to recover, you can add in foods like scrambled eggs.

Treatments and remedies

Treatments and remedies

Many cases of diarrhea are short-lived and respond well to home treatments such as a modified diet, heavy fluid intake, and over-the-counter (OTC) medications. OTC treatments include anti-diarrheal medications like Pepto-Bismol, which can help stop or slow down the diarrhea.

In some cases, diarrhea is caused by parasites or a bacterial infection, and it may need to be treated with antibiotics. Taking probiotics as soon as possible after the diarrhea can help prevent adverse reactions to the antibiotics by introducing healthy bacteria back into the digestive system. This can also help prevent future cases of diarrhea.

If the diarrhea is severe, you may need to be admitted to the hospital for intravenous fluids.

Outlook

Outlook

Your diet can both cause and treat diarrhea. When you have diarrhea, get lots of rest, drink plenty of water, and start introducing BRAT foods after a few hours. After a day or two of bland, soft foods, you can start to add in foods like lean ground chicken and scrambled eggs. Sticking to this diet can help you recover faster and feel better sooner, so you can get back to eating all the foods that you love as soon as possible.
