Treatment for gastroenteritis

may include medicines to stop your diarrhea and vomiting. You may also need medicines to treat an infection caused by bacteria or parasites.

Manage your symptoms:

  • Drink liquids as directed. Ask how much liquid to drink each day and which liquids are best for you. You may need to drink more liquids than usual to prevent dehydration. Suck on ice or take small sips of liquids often if you have trouble keeping liquids down.
  • Drink oral rehydration solution (ORS) as directed. An ORS contains water, salts, and sugar that are needed to replace lost body fluids. Ask what kind of ORS to use and how much to drink.
  • Eat bland foods. When you feel hungry, begin to eat soft, bland foods. Examples are bananas, clear soup, potatoes, and applesauce. Do not eat dairy products, alcohol, sugary drinks, or caffeine until you feel better.

Prevent the spread of germs:

  • Wash your hands often. Use soap and water. Wash your hands after you use the bathroom, change a child's diapers, or sneeze. Wash your hands before you prepare or eat food.
  • Clean surfaces and do laundry often. Wash your clothes and towels separately from the rest of the laundry. Clean surfaces in your home with antibacterial cleaner or bleach.
  • Clean food thoroughly and cook safely. Wash raw vegetables before you cook. Cook meat, fish, and eggs fully. Do not use the same dishes for raw meat as you do for other foods. Refrigerate any leftover food immediately.
  • Be aware when you camp or travel. Drink only clean water. Do not drink from rivers or lakes unless you purify or boil the water first. When you travel, drink bottled water and avoid ice. Do not eat fruit that has not been peeled. Avoid raw fish or meat that is not fully cooked.

Follow up with your healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.
