I cam back from trip to NZ two and a half years ago with what i though was a tummy bug. I ahve had every test under the sun 3 times. Stool sames fine,urine fine hormones fine. The only test that comes back abnormal is Liver function. I hae increased enzymes. I dont had hepatitis and the doctors are stuck with whats wrong. My current 3rd optinion doctor has me on a liver cleansing diet but i still feel nauseous and headachy majority of th time. it seems to come in waves, i have it most of the time. My latest liver test showed bili 25. Its not badly out but something is happening to make me so sick all the time.my AST and ALT were high but on the last test come down. My ultrsounds show fatty liver, but im 28 dont drink, eat really well and im not over weight. I am so over it and extremely frustrated! help!
