Hello dear, The symptoms as mentioned in your post can be due to: 1. Any infection in the Gastrointestinal tract 2. Irritable Bowel Syndrome 3. Increased gas production due to dietary factors or allergy to certain food products. The feeling of tiredness & lack of concentration can be attributed to inadequate hydration status & electrolyte imbalance in the body, which is secondary to your Gastrointestinal pathology. Though symptomatic relief can be obtained with Pantoperazole & Dicyclomine preparations, the underlying cause needs to be treated. So, kindly consult a Gastroenterologist & get a proper clinical examination done. Investigations like stool microscopy & culture, Ultrasound scan of abdomen & colonoscopy will be helpful. Till then, maintain adequate hydration & take soft, non-spicy diet. There is no need to worry...you will be fine. Wishing you a good health & a speedy recovery Thanks & take care.
