Introduction
If GGT is slightly low, it may be due to insufficient intake of protein and meat in the diet. This can usually be improved by increasing nutritional intake and does not pose harm to the body. However, if GGT is severely low, it often indicates underlying liver disease, possibly at an advanced stage where liver cells have lost their ability to synthesize GGT. Without timely treatment, this condition may affect the patient's normal daily life.
Low GGT usually refers to low levels of gamma-glutamyl transferase (GGT). Slight decreases in GGT often indicate malnutrition and generally do not pose significant harm to the body. However, severely low levels may suggest underlying liver disease, which, if left untreated, could lead to serious health complications.
Gamma-glutamyl transferase is primarily located in cell membranes and mitochondria. It participates in glutathione metabolism and helps liver cells metabolize various substances from both inside and outside the body. Most GGT found in serum originates from the hepatic and biliary systems. Normally, the reference range for GGT is 10–60 U/L in men and 7–45 U/L in women. A mildly low level typically indicates malnutrition, possibly due to insufficient dietary intake of protein and meat. Increasing consumption of protein-rich and fatty foods can significantly improve this condition, which otherwise poses no major health risk.
Severely decreased GGT levels may indicate liver diseases such as primary or secondary biliary cirrhosis. This condition often occurs in advanced stages when liver cells have lost their ability to synthesize GGT. Without timely treatment, it may impair digestion and metabolism, and in severe cases, significantly affect the patient's daily life.
