Hi Dear,
Welcome to HCM.
Understanding your concern. As per your query you have symptoms of recurring burps,
abdominal pain, projectile vomiting and diarrhea. Well the symptoms you mention in query can occur due to many reasons like food poisoning ,
food allergy, poor digestion, improper metabolism, infection of digestive system , gas ,
acid reflux ,
stomach flu or colic . Need not to worry. You should take oral rehydration solution as well. I would suggest you to sips of water or other clear fluids on a very frequent basis. You should avoid solid foods for a few hours try small amounts of mild foods such as rice, applesauce and do not take foods or drinks caffeine , carbonated beverages , citrus and dairy products. If condition doesn't get better then
consult gastroenterologist for proper examination and get complete examination done. Doctor may prescribe antiemetic drug , antibiotics ,analgesic and antacid .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
