Hi.
Thanks for your query and an elucidate history.
Your problem looks to be of
Irritable bowel syndrome (IBS).
Before we can say this to be IBS, we need to rule out other organic causes by doing upper GI
endoscopy, Lower GI (
colonoscopy) endoscopy, Contrast enhanced
CT scan of the abdomen, X-ray chest and routine blood/ urine and stool tests.
If everything is normal , then only we can label this as IBS.
One course of an antibiotic ,
metronidazole, anti-spamodic, for 5 days and probiotics to be continued; Vitamin -A 6 capsules and Vitamin D 3 sachets over 3 days will help you the most.
But at the same time you have to take care: stop all the foods and beverages you have noticed to increase your problem , STRESS_ free lifestyle, all helps in such cases.
