My 6 year old girl is lactose intolerant, she is a really good eater with a healthy appetite. On saturday she had stomach pain and vomited, she has since had stomach pain ever since and doctor said glands in her neck were up, on tuesday she started with foul smelling watery diarrhea, she is still having loose stools, foul smelling flatulence & her stomach is very swollen. She seems well in herself but is refusing to eat and gagging, she has never lost her appetite before.
Hi, most probably the child is suffering from stomach infection or acute gastritis. In stomach infection or acute gastritis, there are vomiting fever and loose stools. The first thing that you have to take care is of deny Chat Doctor.  Give child more Fluids and ORS solution. Also start prebiotic like enterogermina ampule once a day for 3 days. For vomiting, you can give syrup containing ondansetron 0.2 milligram per kg 3 times a day for one day. If child does not improve or loose stools and vomiting persists, then child should be started on antibiotics like metronidazole. However, dose of antibiotic is based on weight of child. I advise you to meet the local doctor for needful. Avoid food from outside and give liquid diet to child. Take care. Regards
