Viral gastroenteritis is caused by one of several viruses that assault the intestines. The viruses are usually spread through contact with someone who is infected or with something he or she touched. Viral gastroenteritis also can spread through food or water that is contaminated.
Your doctor will ask about your symptoms and medical history, and perform a physical exam. Your doctor may also order a stool culture. This test looks for bacteria in a stool sample, which would indicate a different type of illness.
There is no specific medical treatment for viral gastroenteritis. Antibiotics are not helpful for infections caused by a virus. However, there are a number of things you can do to be more comfortable and avoid dehydration.
Fluids—It is important to drink fluids to replace those you’ve lost when sick. Take small sips of water, suck on ice chips, or drink clear soda or noncaffeinated sports drinks. Give your child an oral rehydration solution (such as Pedialyte) instead of water.
Diet—Gradually begin to eat bland foods, such as toast, crackers, bananas, rice, chicken, and potatoes. Avoid dairy products, caffeine, fatty foods, and spicy foods until you’re feeling better.
If you’re breast-feeding an infant who is sick, continue to breast-feed. If your baby is bottle-fed, give him or her oral rehydration solution or formula.
Rest—Make sure you get enough rest while you’re sick and when you’re recovering. If your child is sick, make sure he or she gets plenty of rest.
