Did you doctor run standard lab tests? Should have run the full gamut - liver, electrrolytes, adrenal and thyroid. Need to see those.
Ask your general physician to refer you to a gastroenterologist immediately. He should evaluate you for gastric reflux disease. However, I would also strongly urge you to have him evaluate you for Heliobacter pylori infection. He will most likely order a simple breath test, developed in recent years that is a reliable way to assess H pylori infections.
Print this post and the article out (link below), and take it with you. Tell him that I suspect a three way correlation between unusual bile acid stoichiometry, use of tight binding steroids that altered cholesterol metabolism and raised LDL and VLDL significantly, and that I suspect you have strong potential for a concurrent H pylori infection. He can verify your liver lipid chemisty abnormalities from the lab tests (you should make sure they are forwarded to him from your general practitioners office).
After you are evaluated, return here. Let us know of the diagnosis.
