Vomiting and Diarrhea

Most of the time vomiting and diarrhea are caused by “gastroenteritis,” an inflammation in the intestines caused by a virus or bacteria. Mild abdominal cramping may also occur.

How should I care for myself when I have vomiting and diarrhea?

The best approach is to put your stomach and intestines at rest.

It is important to follow a special diet to prevent becoming dehydrated from vomiting, diarrhea, or fever.

  1. Do not eat or drink fluids for two hours after vomiting.
  2. After two hours of resting your stomach, take small sips of clear liquids each hour for a few hours
  3. If no vomiting has occurred start to slowly increase the amount of fluid you are drinking
  4. If vomiting starts again return to step #1
  5. Resting as much as possible helps to decrease diarrhea
  6. Avoid smoking and alcohol

Vomiting and diarrhea may be contagious, so it is important to wash hands well after using the bathroom.

For Diarrhea Only

For diarrhea only, push clear liquids as tolerated. Good examples of clear liquids are as follows:

  • Water, ice chips, popsicles (not creamy)
  • Broth
  • Gatorade
  • Jell-O (plain) or clear fruit juice (non-citrus only)
  • Gingerale

When Vomiting Stops

When vomiting has stopped for 8 hours, and/or diarrhea slows down, begin a bland diet:

  • Bananas
  • Cooked pasta, rice
  • Toast/white bread
  • Applesauce
  • Soup with noodles
  • Oatmeal made with water

Avoid dairy products and meat for at least 36 hours. Also avoid large meals, coffee, alcohol, fatty, fried, greasy foods (hamburgers, hot dogs, hoagies), highly seasoned or spiced foods (pizza, tomato products), salad dressing, oil, butter, and raw vegetables until you feel better. Follow a bland diet for 1 to 2 days.
