Thanks for posting your concern on HCM!
I appreciate your concern towards the high
ALT (SGPT) level.
Age, gender, problem for which ALT is advised, and its duration, alcohol intake if any are not mentioned.
Normal Adult Range for ALT : 0 - 48 U/L
Therefore, ALT in your case is slightly elevated. So, as your old physician suggested you need not have to worry about it.
You need to have some life style modifications to reduce the level of ALT.
Daily physical exercise, eat healthy balanced diet preferably fresh fruits and vegetables which contain several anti-oxidants that help in reducing the ALT, AVOID ALCOHOL if any, avoid fatty vegan and non vegan meals, fast junk foods, take plenty of oral fluids. Insha Allah, in due course of time your ALT will be normal.
Wishing you best of your health.
