He and welcome to HCM.
YOu shouldnt be concerned. These are only mildly elevated AST. It can becaused by excessive exercise or smoking. Also some temporary liver damage
can cause it as well, but you dont need to be concerned. He should continue with healthy diet and life. Also, he should do ultrasound
to see is there any liver damage or gallbladder
disorder. If something is found such as fatty liver
or fibrosis then he should do virla markers and take certain medicines. WIsh you good health.
