constant fatigue and Blood Test Results

Hey, I went to the doctor about constant fatigue and he ordered a full blood test. Results show very low Vitamin D (33.3mol/L) and high Vitamin B12 (856ng/L). So he's given me Vitamin D supplements to take.

Liver function tests also showed up the following:

High GGT - 89 iu/L (normal range is 2-50)
High ALT - 66 iu/L (normal range 0-40)
Normal AST - 37 iu/L
Normal ALP - 36 iu/L
Normal Albumin - 41g/L
Normal Bilirubin - 12 umol/L

He's now ordered blood tests to check for Hepatitis, and a liver ultrasound, but says he doesn't know enough to even speculate yet.

Any advice?

Thanks,

Gareth
