Hello dear, The symptoms as mentioned in your post is attributed to either infection or inflammation in the Gastrointestinal tract. Management involves: 1. Tablet Pantoprazole + Domperidone twice daily (to be taken half an hour before food) 2. Anti spasmodics like Dicyclomine preparation twice daily (to be taken after food). 3. Oral Rehydration Solution (O.R.S) for maintaining the hydration status & electrolyte balance of the body. 4. Take soft, plain, non-spicy foods. 5. Avoid fast foods & gas producing food products like cabbage, etc. Investigations like complete blood count, estimation of serum electrolytes & Ultrasound scan of abdomen & Pelvis will be helpful in detecting any pathological cause for the symptoms. There is no need to worry, he will be fine. Wishing a good health. Take care.
