What are the causes of low transpeptidase levels?

　　In clinical practice, transpeptidase refers to gamma-glutamyl transferase (GGT). Low levels of gamma-glutamyl transferase may result from non-disease factors or disease-related causes such as viral hepatitis and toxic hepatitis. The specific analysis is as follows:

　　I. Non-disease factors

　　If an individual habitually has poor dietary habits and consumes insufficient protein-rich foods, the level of gamma-glutamyl transferase may slightly decrease. This typically does not cause significant discomfort. The condition can usually be improved by appropriately increasing intake of protein and fatty foods.

　　II. Disease-related factors

　　1. Viral Hepatitis

　　After the liver is infected with a virus, inflammatory stimulation can impair hepatocyte function, leading to decreased gamma-glutamyl transferase levels. It is recommended to take antiviral medications such as entecavir dispersible tablets, lamivudine tablets, or daclatasvir hydrochloride tablets under medical guidance to improve symptoms.

　　2. Toxic Hepatitis

　　Prolonged exposure of the liver to irritants such as alcohol, tobacco, or chemical toxins can easily lead to toxic hepatitis. When hepatocyte necrosis is severe, gamma-glutamyl transferase levels may also decrease. It is recommended to follow medical advice and receive intravenous administration of hepatoprotective and detoxifying agents such as compound glycyrrhizin injection, reduced glutathione injection, or hepatic hydrolyzed peptide injection.

　　Additionally, low GGT levels could also be caused by conditions such as bile duct obstruction, liver cirrhosis, or primary liver cancer. Specific diagnosis requires appropriate medical evaluation and relevant examinations at a hospital to determine the underlying cause and initiate suitable treatment.
