Hi.
Thanks for your query.
Noted the history and understood the concerns.
our problem started with
constipation and loss of appetite for 5 day about a month ago which got relieved later but the pain in left upper abdomen below
rib cage, consultation with a Gastroenterologist to tell you this being IBS not yet relieved needs further evaluation.
No complete evacuation, boating and further symptoms indicate that you should go or detailed clinical evaluation and investigations as follows>
Colonoscopy after preparation.
CT scan of abdomen Tests of blood, stool and urine.
If a specific cause for your symptoms is found out, you will be treated accordingly.
If all the investigations are normal, then alone this can be considered to be IBS that is
irritable bowel syndrome and control of stress and/or
anxiety can give the best results.
Also important is to see for any intolerance to foods, beverages or any other factors and be stopped altogether.
