Symptoms of high liver enzymes can vary depending on the cause and may include abdominal pain, nausea, yellowing of the skin or eyes (jaundice), dark urine, or pale stools. These symptoms are more likely when high liver enzymes are related to liver or bile duct problems.
A high GGT level, which is one type of liver enzyme, often does not cause symptoms or relate to any specific complaints. It may be elevated due to alcohol use or as a side effect of certain medications, such as phenobarbital or phenytoin.
Even if you don’t have any symptoms of elevated liver enzymes, it’s still important to follow up with a gastroenterologist or the doctor who ordered the test. GGT blood test results are typically reviewed together with other blood tests to help determine the cause of the elevated levels.
