### input:
I have a 10 yr old son that has high liver enzymes..he has ADHD and in the last 10 months has been on vyvanse..he was diagnosed at the age of 3 with ADHD and was on stratera for 5 yrs,and when we switched his meds to adderall xr ( was on it for 2 yrs) is when we found out his liver enzymes were high..his highest was 185 and his lowest was 60..we have been to a ped.GI and have had a liver biopsy done.. All they can figure out is that it s an unknown liver disease..they have tested for EVERYTHING...My son weighs 49 pounds and is 4 foot tall..we are curently waiting on more labs on all growth hormones (pituitary glands) and on his chromizomes.. My son needs his ADHD meds but his regular doc s want to wait a month n retest his emzymes before putting him back on it....But I can t wait that long...What else can a person test for to get answers on the high liver enzymes? He is on high calorie diet and the vyvanse breaks down in the kidnies....

### output:

Hello, Liver enzymes, liver biopsy, pituitary hormones, chromosomal studies, etc., almost everything has been done and I don't think further investigations are needed. Vyvanse (Lisdexamfetamine) can cause hepatitis and increase liver enzymes hence your doctor is not starting that medicine. You should wait for reports for retest of enzymes. Hope I have answered your query. Let me know if I can assist you further.
