Hello I really appreciate your concern, this can be caused by food poisoning or intestinal infection like gastroenteritis or food allergy I would like further information to help you better since how long you have this problem? Is it associated with acid reflux or regurgitation or pain in abdomen In my opinion you should see your doctor for stool test for ova cyst or protozoa and course of antibiotics if it is a chronic problem Otherwise have lots of fluids including ORS and fruit juices to counter dehydration and electrolytic imbalances Maintain good hygiene You should take pantoprazole or omeprazole with antacids You can take curd, yogurt or banana as a home remedy Hope this helps you Best wishes
