Thank you for the query.
Such symptoms can appear due to pregnancy
. It should be checked at first. Other possible reasons are severe intestines infection, stomach mucosa inflammation, peptic ulcer
, gallstones. It is advisable for you (if pregnancy ruled out) to have abdominal ultrasound, full blood work with liver tests (AST,ALT,GGTP), amylase, bilirubin
, urine analysis and stool tests. If no findings, upper GI endoscopy should be done. You should also consult gyneacologyst for transvaginal ultrasound
Hope this will help.
