Glutamyltransferase (GGT) is an important component involved in protein metabolism in the human body and is mainly found in the liver, kidneys, pancreas and other substantial organs. temporary increase in GGT may be caused by liver and biliary injury due to recent poor lifestyle habits such as overeating, overexertion and heavy alcohol consumption. Generally, after improving lifestyle habits, some patients can reduce to normal range. In addition, persistently high GGT levels may also be related to the following types of diseases: 1. Liver and gallbladder diseases: Gallbladder disease, gallstones, acute hepatitis, fatty liver, alcoholic cirrhosis and other liver and gallbladder diseases can affect the normal function of the liver and lead to liver and gallbladder damage, which in turn may cause high GGT levels in the body. Usually patients with hepatobiliary dysfunction also have yellow staining of the skin and sclera; 2. Pancreatic diseases: acute pancreatitis, pancreatic tumors and other pancreatic diseases can cause obstruction of the pancreatic ducts, resulting in bile stasis, so patients can have increased levels of GGT in the body. Most patients will also experience acute abdominal pain, fever, nausea, vomiting and other symptoms; 3. Other diseases: such as heart failure, myocardial infarction, prostate tumor, etc., may also lead to an increase in the level of GGT in the body. There are many causes of elevated levels of GGT in the body. Patients with abnormal symptoms such as local pain, jaundice, fever, chest tightness, etc. are advised to go to the hospital immediately to improve relevant examinations to avoid serious organic lesions.
