SPRINGFIELD, Mo. -

If your stomach is a little unsettled and you're not sure why, you could be coming down with the stomach bug.

That's what's going around this week and a lot of people are getting sick with it from counties all around the Ozarks.

Symptoms include nausea, vomiting and diarrhea.

These can last one day or up to a week and can be mild or severe.

“Treatment for gastroenteritis is hydration, and rest,” explains Mindy Kendrick with Ozarks Community Hospital’s Primary Care clinic in Springfield. “You can call your health care provider and they can prescribe something for nausea and vomiting. Start on your diet with clear liquids and advance to solid foods for a couple of days.”

Health officials say when you get back to solid foods, remember the BRAT diet.

B for bananas
R for rice
A for applesauce
T for toast

If these foods don't make you sick, then move on to other foods.

Doctors say to avoid milk products because they can irritate your stomach.

If you get the stomach bug, dehydration is a big worry.

Symptoms of dehydration include dry mouth, light-headedness, confusion and muscle cramps.

Make sure you're drinking plenty of water or sports drinks so you don't get dehydrated if you get the stomach flu.
