Diet for Diarrhea, Adult

Having frequent, runny stools (diarrhea) has many causes. Diarrhea may be caused or worsened by food or drink. Diarrhea may be relieved by changing your diet.


  • Drink enough water and fluids to keep your urine clear or pale yellow.

  • Avoid sugary drinks and sodas as well as milk-based beverages.

  • Avoid beverages containing caffeine and alcohol.

  • You may try rehydrating beverages. You can make your own by following this recipe:

  • ½ tsp table salt.

  • ¾ tsp baking soda.

  • ⅓ tsp salt substitute (potassium chloride).

  • 1 tbs + 1 tsp sugar.

  • 1 qt water.

As your stools become more solid, you can start eating solid foods. Add foods one at a time. If a certain food causes your diarrhea to get worse, avoid that food and try other foods. A low fiber, low-fat, and lactose-free diet is recommended. Small, frequent meals may be better tolerated.
