What is gastroenteritis?
Gastroenteritis, or stomach flu, is an infection of the stomach and intestines. Gastroenteritis is caused by bacteria, parasites, or viruses. Rotavirus is one of the most common cause of gastroenteritis in children.
What increases my child's risk for gastroenteritis?
- Close contact with an infected person or animal
- Food poisoning, such as from eggs, raw vegetables, shellfish, or meat that is not fully cooked
- Drinking water that is not clean, such as when you camp or travel
What are the signs and symptoms of gastroenteritis?
- Diarrhea or gas
- Nausea, vomiting, or poor appetite
- Abdominal cramps, pain, or gurgling
- Tiredness, weakness, or fussiness
- Headaches or muscle aches with any of the above symptoms
How is gastroenteritis diagnosed?
Your child's healthcare provider will examine your child. The provider will check for signs of dehydration. The provider will also ask you how often your child is vomiting or has diarrhea. Tell the provider how much your child is drinking and urinating. Your child may need a blood or bowel movement sample tested for the germ causing his or her gastroenteritis.
How is gastroenteritis managed?
Gastroenteritis often clears up on its own. Medicine is usually not needed to treat gastroenteritis in children. The following will help prevent or treat dehydration:
- Continue to feed your baby formula or breast milk. Be sure to refrigerate any breast milk or formula that you do not use right away. Formula or milk that is left at room temperature may make your child more sick. Your baby's healthcare provider may suggest that you give him or her an oral rehydration solution (ORS). An ORS contains water, salts, and sugar that are needed to replace lost body fluids. Ask what kind of ORS to use, how much to give your baby, and where to get it.
- Give your child liquids as directed. Ask how much liquid to give your child each day and which liquids are best for him or her. Your child may need to drink more liquids than usual to prevent dehydration. Have him or her suck on popsicles, ice, or take small sips of liquids often if he or she has trouble keeping liquids down. Your child may need an ORS. Ask what kind of ORS to use, how much to give your child, and where to get it.
- Feed your child bland foods. Offer your child bland foods, such as bananas, apple sauce, soup, rice, bread, or potatoes. Do not give your child dairy products or sugary drinks until he or she feels better.
How can I help prevent gastroenteritis?
Gastroenteritis can spread easily. If your child is sick, keep him or her home from school or daycare. Keep your child, yourself, and your surroundings clean to help prevent the spread of gastroenteritis:
- Wash your and your child's hands often. Use soap and water. Remind your child to wash his or her hands after he or she uses the bathroom, sneezes, or eats.
- Clean surfaces and do laundry often. Wash your child's 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. Give your child only clean water. Do not let your child drink from rivers or lakes unless you purify or boil the water first. When you travel, give your child bottled water and do not add ice. Do not let him or her eat fruit that has not been peeled. Avoid raw fish or meat that is not fully cooked.
- Ask about immunizations. You can have your child immunized for rotavirus. This vaccine is given in drops that your child swallows. Ask your healthcare provider for more information.
