Mild elevations of liver enzymes AST, ALT, and GGT started sometime late 2013 or early 2014 and still are elevated. By mild, AST and ALT around 60 and GGT about 100. Never have had that problem before and hadn't had any alcohol since 1/24/14. Had full bloodwork and ultrasound from a hepatologist a month or so ago and everything was normal except the high enzymes. Note that high dose purified fish oil seems to lower the alt/ast about 10-15 pts but has little effect on GGT. Hepatologist said the only other testing to consider if enzymes stay elevated is a biopsy.
My questions are:
1. How long does it take for mild enzyme elevations to cause permanent damage?
2. Could this be a residual effect of a slo-niacin I took in late 12/13-early 1/14? Thought it might be the culprit but if it were the niacin, I'd think things would be back to normal by now.
3. What other type things can a biopsy show that the vast array of bloodtest and ultrasound wouldn't show? They did a bunch of blood tests I've never heard of before.
4. How accurate is biopsy? Couldn't the needle pick up tissue in an area not inflammed?
