hi,Iam having stomach discomfort and burning sensation for last two weeks.Occassionally I have loose tools too.Last week blood test show an increase in SGOT and SGPT(51 and 151 respectively).Other liver function tests were normal(total protien-6.6,albumin-4.3,globulin-2.3 , A/G ratio-1.8,alkaline phosphatase-95).what can be the possible causes of this elevation.
