[/INST] HiThanks for Asking.Your son is having constant elevation of the liver enzymes, SGOT and SGPT, which is persisting even after 6- 8 weeks.Constant elevation suggests liver damage, there are plenty of reasons of raised liver enzymes likeViral infectionAlcoholToxinsHereditary disordersDrugsIf the levels are persisting, he needs some investigations including the imaging of the liver and the biliary tree to ascertain the cause of the problem.Thanks. </s>
