Hello! Thanks for putting your query in HCM. I am a Gastroenterologist (DM). Elevation of ggt has no prognostic value. However it is increased in few diseases like alcohol related liver disease, biiliary tract obstruction leading to jaundice fever etc, inflammation of gallbladder, hepatitis. So I will suggest you to visit your doctor for physical examination and tests accordingly. I hope I have answered your query and this will help you. If you have any further query I will be happy to answer that too. Remain in touch and get-well soon.
