Dan Moore, certified physician assistant at McLaren-Greater Lansing Internal Medicine, a partner of McLaren-Greater Lansing, is treating viral gastroenteritis.

Most people refer to it as the stomach flu, even though it's not actually a type of flu.

The main symptoms are: stomach cramping or discomfort, bloating, nausea and diarrhea.

Fever is less common, but a low-grade fever not higher than 101 degrees may be present.

Most cases of viral gastroenteritis aren't serious and will clear up in a few days.

Give your stomach time to settle by not eating or drinking for a few hours.

Once it's settled, drink plenty of fluids to avoid dehydration. Kids should drink Pedialyte.

After a 14-hour liquid diet, you can start eating bland foods.

You should see a doctor if you can't keep liquids down for 24 hours, if you've been vomiting for more than two days, or if you have symptoms of dehydration.
