The GGT test can diagnose
liver damage, but it can’t determine the cause. If your GGT level is elevated, you’ll probably have to undergo more tests. Generally, the higher the GGT level the greater the damage to the liver.
Some of the conditions that result in increased GGT include:
overuse of alcohol
chronic viral hepatitis
lack of blood flow to the liver
liver tumor
cirrhosis, or scarred liver
overuse of certain drugs or other toxins
heart failure
diabetes
pancreatitis
fatty liver disease
GGT is often measured relative to another enzyme,
alkaline phosphatase (ALP). If GGT and ALP are both elevated, doctors will suspect that you have problems with your liver or the bile ducts. If GGT is normal and ALP is elevated, this could indicate bone disease. Your doctor may use the GGT test in this way to rule out certain problems.
Liver damage is serious and can often lead to other health problems. Depending on the extent of the damage, it can also be irreversible. The GGT test, used in conjunction with other testing methods, can help your doctor see if you have liver damage.
Be sure to consult your doctor if you have any symptoms related to liver damage so they can test you, uncover the cause, and get you started on a treatment regimen.
Some studies indicate that high coffee intake may lower GGT level in heavy drinkers, but it may take more than five cups per day. Beware, excessive coffee intake creates its own problems, including high blood pressure and sleep difficulties.
Ultimately, quitting smoking, quitting alcohol, and losing weight are important first steps toward lowering GGT levels and allowing the liver to heal while adopting a more healthful lifestyle.
