I had a liver ultrasound, the results came back perfect, nothing was wrong. Also, I did an endoscopy, also nothing was wrong. I used to drink a lot last year, but in may, I started getting acid reflux, so I did a blood test in general, and found that my ggt levels are very high at the time they were 155, I stopped drinking, and had half a beer in october only! but my problem is that the enzymes are still high. I take zoloft. My ggt levels have lowered to 71 in january, and now have increased to 85 again.
