Hello. Thanks for writing to HCM I have studied your case and history. There is possibility of bowel obstruction due to previous surgery or infection possibility below duodenum. I will advise you to investigate like Ultrasonography pelvis and abdomen. If required CT abdomen may be done Till time start antacids [proton pump inhibitors like] rabeprazole -D. There can be possibility associated gastric infection if you are having fever? Or diarrhoea? Try to maintain body fluid by increasing fluid intake, take easily digestible food. You need to consult your treating doctor for further investigation. Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care.
