Hi. Thanks for your query. Noted the history and understood your concerns. Bloating, pain, gastric reflux, congested throat and nose, mouth ulcers and so on indicate that you may have more than one problem that are manifesting in the way as you have noted. Hence I would advise you the following in such a situation: First of all make a list of the foods that instigate or enhance the symptoms so that you can stop these as a preventive measure so that management can be effective. Get stool tests done for three consecutive days. Tests of blood for CBC, thyroid, liver and kidney function with lipase, amylase and any others as may be suggested by your Doctors/ Gastroenterologist on clinical evaluation, examination correlating the reports of investigations. Upper GI Endoscopy, colonoscopy and CT scan of the abdomen will help further to get an exact cause and get treated accordingly. Till then get started on a PPI like Omeprazole, Domperidone for motility regulation, antacids, probiotics; symptomatic and supportive treatment. Any specific disease found will be treated specifically. If all the investigations are within normal limits then this may be the case of IBS that is irritable bowel syndrome. Then you have to get the stress under control either by naturotherapy like meditation, yoga or with medications as required. Change the lifestyle to suit you the best and avoid the symptoms.
