Thank you for the query.
Such symptoms can be caused by pancreatitis
, partial bowels obstruction, intestines infection, food allergies. As it lasts a month, it is time to start some diagnostics. You should have abdominal ultrasound
, abdominal X-ray
, blood work, liver tests (AST,ALT,GGTP), amylase, lipase, urine amylase and stool tests performed. Depending of the results, colonoscopy
might be the next step.
Hope this will help.
