This is Kata, ktdwll's daughter....
My liver enzymes have gone up and down since i had my daughter in July of 09, i also have been in and out of the ER and Hospital with no explanation ( i know that is not good news)... At the end of August / begining of September I finally went to U of ** because i was in sooo much pain and could not eat a thing. When i went in my liver enzymes were up. While i was there they did an ERCP, removed a stone ( that could have been left there since the removal of my gallbladder in aug or 09), and they put a slit in my sphinkter (sp?). When i left my numbers were down, almost back to normal. I dont believe i have ever been givin an explanation on why they go up and down....I have been feeling very good since all of that, but have not gotten any labs done so dont know what my numbers look like!
Hope this helps! Hope your sister feels better!
