I am Dr. Arun and will be helping you today.
I am sorry that your question was unanswered for long.
Following are the diagnostic possibilities for your symptoms;
1) Non functioning and poorly functioning gall bladder: An HIDA scan is required.
2) Gastritis / Gastroesophageal reflux disease / Peptic ulcer; these require upper gastrointestinal endoscopy, Helicobacter pylori testing and a barium meal with follow through study.
3) Irritable bowel syndrome; this will require a colonoscopy and CT scan.
4) Bacterial over growth syndrome; this requires stool exam, Short-chain fatty acid levels, Urine 4-hydroxyphenylacetic acid levels etc to diagnose the issue.
Thus you need further investigative work up which will pin point the issue.
Meanwhile you may take over the counter probiotics which are likely to help you. Please avoid artificial colorings, (especially aspartame), flavorings and preservatives. Excess alcohol should be avoided.
Please feel free for your follow up questions.
I would be happy to assist you further, if you need any more information.
Thanks for using Just Answer.
