Hello! Welcome and thank you for asking on HCM! I agree with you on the fact that liver disorder or biliary tract disorders can cause such symptoms. You should know that gama GT is a liver enzyme, which can result elevated in liver an biliary tract disorder (including biliary stones, inflammation, infection, alcohol intake, etc.). It can also result elevated from different drugs. What is your actual therapy? I would recommend besides kidney and liver function tests, performing an abdominal ultrasound to examine your abdominal organs including the liver and biliary tract. Hope to have been helpful! Greetings! Dr. Iliri
