Hi. Thanks for your query and an elucidate history. Noted the detailed history of your symptoms and treatment history too. It is good that you have been kept on IBS-C regime but one has to be certain. I do advise in all the patients with similar history the following: Firs of all to go for al relevant investigations like that of blood, urine, stool, CT scan of the abdomen, Upper GI Endoscopy and Colonoscopy. Only after all the reports are negative that we can say this is IBS. Secondly it is always better to get a course of 5-day antibiotic, metronidazole and be supplemented for by probiotic, activated charcoal, Domperidone as you have problem of gases and burping too . I am sure this will help you a lot. Please consult a Gastroenterologist for detailed history, investigations and treatment accordingly. If the change of routine helps, the necessity of medicines is drastically reduced to almost nil. Medicines :: You need to have a prescription of a Doctor, please discuss this with a Gastroenterologist to get a prescription. I would like to know which medicines have you taken in the past and in which dosage Vit A and Vit D in therapeutic doses, Multiviatamins , probiotics, anxiolytics help a lot. Remember the simple dictum in IBS : you have to undergo necessary investigations before you are labelled as a patient of IBS. Secondly IBS is easily treatable, controllable and within the ambit of your psychological set-up.
