Hello. Thanks for writing to us. GGT blood levels may be elevated due to liver disease, hepatitis, gallstones, diabetes, pancreatic disease, kidney failure, alcohol misuse, certain prescription drugs, certain herbs and supplements or taking very high amounts of supplements. The mild rise in GGT that you are having does not need any treatment if there are no symptoms. Proper blood investigations are needed to find out the cause under the guidance of your gastroenterologist. I hope this information has been both informative and helpful for you. Regards, Dr. Rakhi Tayal drtayalrakhi@gmail.com
