Vomiting along with loose stool
can be due to Gastro Enteritis, which is infection of the gastrointestinal tract.
Get yourself examined and take some antacids and antiemetics like Ranitidine
Also take some Probiotic
. Take light diet. Avoid spicy and oily foods as they will cause more gastritis.
Drink plenty of pure filtered water.
Please get yourself examined for :-
1. Complete Blood Count
2. Liver Function Test
3. Stool examination
