Thank you for the query.
Your symptoms can be caused by pancreas insufficiency, stomach inflammation
or ulcer, gallstones, bacterial infection. It is advisable for you to have abdominal ultrasound
, blood work, liver tests (AST,ALT,GGTP), amylase, urine amylase, lipase, bilirubin
, urine analysis, stool tests. If no findings, upper GI endoscopy
should done and abdominal CT (for pancreas diagnostics).
If all this tests will be negative, you should try Rifaximine treatment ordered by your doctor.
Hope this will help.
