No, not really.
What's often called "stomach flu" is gastroenteritis, an infection of the stomach and intestines. The flu, or influenza, is different. It causes fevers, sore throats, runny noses, and general aches and pains. It usually does not cause stomach problems.
Viral infections are the usual cause of gastroenteritis. Bacteria can sometimes bring it on.
The sickness usually passes in about 10 days without medication. The first few days tend to be the worst, but you can take steps to help your child get through this tough time.
Give lots of fluid. The biggest danger from gastroenteritis is dehydration. Your child's body loses more fluids than it takes in. So, the most important thing you can do is keep your child hydrated, says Andrew Nowalk, MD, PhD. He's an assistant professor of pediatrics at Children's Hospital of Pittsburgh.
Not just any fluid will do. Water is good, but in some cases, it may not be enough. It won't replace the important electrolytes (salt and minerals) your child's body loses when it's dehydrated.
Drinks that do replace salt and minerals are called electrolyte solutions, or oral rehydration solutions. You can buy them at your local drug store. They can even be bottle-fed to infants.
Some sports drinks promise to replace electrolytes as well. They have a lot of sugar, but are okay for most school-age children and teenagers. They're not a good idea for very young children, though, says Peggy Pelish, PhD. She's a pediatric nurse practitioner with the University of Nebraska Medical Center College of Nursing.
Keep children away from milk. It can make stomach problems worse. If you're the parent of a young baby, talk with your doctor about breastfeeding or formula.
Drinks that have a lot of acid (orange juice) or caffeine can also cause belly problems.
Too much of even the right kind of liquid can make vomiting worse, so take it slow at first. Try 1 teaspoon every 4 to 5 minutes, Nowalk says.
Introduce food slowly. Once your child can drink liquid and keep it down, you can start adding food. But keep it bland. Try bread, potatoes, plain yogurt, crackers, rice, toast, and bananas first. Once you know those are going down okay, you can try lean meat and cooked vegetables.
Don't give your sick child foods that are fried, spicy, fatty, or have a lot of acid. They can make stomach problems worse.
Skip over-the-counter meds. With gastroenteritis, time really is the best medicine. Watching your child suffer may tempt you to give him over-the-counter medicines. As hard as it is, don't do it. Not only will most medications not help, they may even make it worse.
Ibuprofen can upset your child's stomach even more, and acetaminophen can cause liver problems. Antibiotics don't help against viruses (although they do against bacteria). And anti-diarrhea medicines can make the infection last longer. They can also be dangerous for very young children.
There is one exception: If your child has a fever, you can give them acetaminophen or Ibuprofen to bring it down. Other than that, stick with fluids and bland foods.
When to See Your Doctor
Most cases of gastroenteritis go away on their own. See the doctor if the vomiting and diarrhea continues more than a few days, or if you notice any signs of dehydration like:
- Not urinating
- Dry mouth
- Crying without tears
- Fever over 102 F
- Lack of energy
- Soft spot on the top of the baby's head is sunken.
- Blood or pus in stool, or dark tarry stool
Your child may need to get checked sooner if they have other conditions, such as diabetes, that put them at higher risk for fluid loss.
Prevention Is the Best Medicine
Follow these easy steps.
- Get your child vaccinated against rotavirus, which is the most common cause of gastroenteritis.
- Wash hands often with warm soap and water, especially when you use the bathroom, change diapers, and before and after you handle food. "Good soap and water hand-washing is probably our best protection," Nowalk says.
- Wash all fruits and vegetables before eating them. Cook meat all the way through. This may prevent gastroenteritis caused by bacteria.
