You have a recent onset of lower abdominal pain
vomimting ,diarrhea and considerable weight loss. This is
of concern along with your elevated liver enzymes
levels. You need a very complete work up. This should include
CT-Scan of the abdomen and pelvis along with some cancer
markers such as CEA,CA-19-9,AFP (Alpha feto protein) etc.
You also need to have tests for Celiac disease
and IBD markers.
(Inflammatory Bowel Disease
) to rule out Crohn's disease.
You may need endoscopic examination of your stomach and
colon to check the last part of the small bowel called the Ileum
to look if there is evidence of inflammation. You need to check
your stool for hidden blood, if there is no obvious bleeding.
You need to have Thyroid and Parathyroid glad blood tests
to look for over activity of these glands. Parathyroid gland
is responsible for calcium metabolism
and any excess acitivity
due to tumor in this gland can cause diarrhea and incresed
I hope that I have given you enough information for you to
discuss with your own doctor to have these studies done.
I wish you the very best.
