In Okemos, Dr. Dennis Perry at Meridian Primary Care, a partner of McLaren Greater Lansing, is treating gastroenteritis.

The main symptoms are: stomach cramping or discomfort, bloating, nausea and diarrhea. Fever is a less-common symptom, but a low-grade fever may be present.

Most cases of viral gastroenteritis aren't serious and will clear up on their own without specific treatment within a few days.

You should let your stomach settle by not eating or drinking for a few hours. Start a liquid diet and once you can keep down liquids for 24 hours, begin a BRAT diet (bananas, rice, applesauce, toast).

Use medications like ibuprofen sparingly because they can upset your stomach.

See a doctor if you can't keep liquids down for 24 hours or you've been vomiting for more than two days.

The most dangerous complication to watch out for is dehydration. Young children and the elderly are particularly susceptible.
