Gamma GT, also known as Gamma Glutamyltransferase, is a liver enzyme which is raised in liver and bile duct diseases. It is used in conjunction with ALP to distinguish between bone or liver disease. Gamma GT is also used to diagnose alcohol abuse as it is raised in 75% of long term drinkers.
What might a low result mean?
Both normal and low results indicate that it is very unlikely that you have liver disease.
What might a high result mean?
Elevated levels of Gamma-GT can be caused by liver diseases such as hepatitis and cirrhosis. This is because when the liver is damaged it can leak its contents, such as enzymes, into the bloodstream. Levels can also rise in people with bile duct blockages due to ailments such as gallstones and gallbladder tumours.
Levels of Gamma-GT are also raised due to alcohol abuse and is often a clear sign that alcohol intake needs to be reduced to prevent permanent liver damage.
How might I improve my result?
Improving your GGT depends on the reason for your elevated result. If excessive alcohol consumption is suspected, then the most important thing you can do is to moderate your drinking or stop altogether to enable your liver to recover. Your liver has amazing powers of regeneration, but if liver damage progresses, then scarring (cirrhosis) could occur which then becomes irreversible.
