WHY GGT IS HIGH

WHY IS GGT HIGH?

GGT, or gamma-glutamyl transferase, is an enzyme found in many tissues throughout the body, with high concentrations in the liver, kidneys, and pancreas. Its primary function is to break down glutathione, an antioxidant that helps protect cells from damage.

GGT levels in the blood are typically low, but they can become elevated in response to certain conditions, including liver and bile duct diseases, alcohol abuse, and certain medications.

Causes of High GGT levels

There are a number of conditions that can cause high GGT levels. Some of the most common include:

  • Liver disease: This is the most common cause of high GGT levels. Liver diseases that can lead to elevated GGT include hepatitis, cirrhosis, and fatty liver disease.

  • Bile duct disease: Conditions that affect the bile ducts, such as cholecystitis (inflammation of the gallbladder) and cholangiocarcinoma (cancer of the bile ducts), can also cause high GGT levels.

  • Alcohol abuse: Drinking alcohol in excess can damage the liver and lead to high GGT levels.

  • Certain medications: Some medications, such as phenytoin (used to treat seizures) and methotrexate (used to treat cancer and autoimmune diseases), can raise GGT levels.

  • Other conditions: A number of other conditions, including heart failure, kidney disease, and diabetes, can also cause high GGT levels.

Symptoms of High GGT Levels

High GGT levels do not usually cause any symptoms. However, the underlying condition that is causing the high GGT levels may cause symptoms. For example, liver disease can cause fatigue, nausea, vomiting, abdominal pain, and jaundice (yellowing of the skin and eyes).

Diagnosis of High GGT Levels

High GGT levels are typically diagnosed with a blood test. If your GGT levels are high, your doctor will likely order additional tests to determine the underlying cause. These tests may include:

  • Liver function tests: These tests measure the levels of various enzymes and other substances in your blood that are produced by the liver.

  • Imaging tests: These tests, such as an ultrasound or CT scan, can help your doctor visualize your liver and bile ducts.

  • Biopsy: In some cases, your doctor may recommend a biopsy of your liver to confirm a diagnosis of liver disease.

Treatment of High GGT Levels

The treatment for high GGT levels depends on the underlying cause. For example, if your high GGT levels are due to liver disease, your doctor may prescribe medications to treat the liver disease. If your high GGT levels are due to alcohol abuse, your doctor will likely recommend that you stop drinking alcohol.

Conclusion

High GGT levels can be a sign of an underlying medical condition. If you have high GGT levels, it is important to see your doctor to determine the cause and receive appropriate treatment.
