The possible causes of high glutamyl transpeptidase 79 are hepatitis and cirrhosis, which need to be treated according to the causes, such as viral hepatitis which needs to be treated with interferon and so on. 1. Viral hepatitis: patients with viral hepatitis may have elevated glutamyl transpeptidase, patients need to avoid drinking alcohol, if necessary, take interferon, lamivudine and other drugs for treatment. Interferon may appear fever, headache, fatigue and other side effects; lamivudine may appear after taking symptoms of allergic reactions such as sweating, chest tightness, panic. 2. Alcoholic liver disease: For patients who drink a lot of alcohol over a long period of time, glutamyl transpeptidase will be significantly elevated.

Hepatoprotective drugs may have adverse effects such as dyspepsia and abdominal pain. 3. Cholestatic liver disease: The triggers of cholestatic liver disease may be immunity, infectious factors, stones, etc., and its glutamyl transpeptidase may be elevated, and certain liver-protecting treatments should be given, such as liver-protecting treatments with silymarin capsules, and glucocorticosteroids to regulate immunity can be used at the same time. Silymarin capsules may cause side effects such as eructation and anorexia; glucocorticoids may cause electrolyte disorders.
