Thank you for the query.
Dark urine usually indicates bilirubin
presence in it. Bilirubin appears in the urine in case of jaundice. Jaudice associated with nausea caused by a meal sounds like a gallstone
in bile ducts which occasionally obstructs them. You may also suffer from whitish stool, upper right abdominal pain
, radiating to the back.
Other jaundice reasons like liver cirrhosis
, liver viral infection should be also considered.
I suggest you to have some tests done. Abdominal ultrasound
, blood work, liver tests (AST,ALT,GGTP), bilirubin, amylase, urine amylase, urine analysis should be done at first. In case of lack of gallstones, liver viral tests should be also done.
Hope this will help.
