Hi I am new here but am worried as I have had liver tests done and I have a GGT of 270 and and ALP of 138. I am a 45 y/o male and in generally good health. I do not drink very much (and had not drank anything few a few days before this) but do take Omeprazole daily 20-40 mg and also take Ibuprofen daily 400-600 mg for kidney stones/pains and I also take Alprazolam 0.5 mg per night and Zolpiclone also at night for insomnia. I've been trying to not take any Ibuprofen, have tried to switch to Zantac instead of the Omeprazole and have radically changed my diet since all this happened (this all started with a bad reaction to taking an antibiotic for a sinus infection, which caused hot flashes and abdominal pain...antibiotic was Erythromycin). I am really worried that I might have biliary obstruction or something and the Doctor has ordered a Ultrasound of my liver for next week. Should I be worried about this or could it be fatty liver? Also, had my gallbladder removed in 1997 so no gall stones to cause a biliary obstruction...any advice or help you can provide is greatly appreciated!
