Talk to Gastroenterologist on Gastritis (Possibly)

Last month, my daughter had a bad case of diarrhea. They hooked her up on an IV Drip for Flagyl, and another that I can't remember the name of. It was happening every 30 minutes, in short spurts. She got her period the same day this happened.

She was feeling nauseous last week and vomited on Monday. I gave her a Flagyl Syrup for two days, twice per day. She started getting stomach aches yesterday. Today, she's had diarrhea thrice. She hasn't vomited again since Monday.

She drinks too much coffee; I think that's what's causing it. Her diet is bad. She barely eats some rice and chicken for lunch. I get her some sweet snacks (a donut?) for later during the day. I force her to drink a mango shake, mostly.
