Disease description:

My grandmother has fatty liver disease. When she went to the hospital for a checkup yesterday, the doctor said her GGT was high. Can fatty liver cause elevated GGT?

Doctor's answer (1)
Dr. Zhao Haiming
In patients with fatty liver, GGT levels may increase to some extent, primarily because fatty liver can easily lead to fat accumulation, resulting in hepatocyte injury and consequently elevated gamma-glutamyl transferase (GGT) levels. It is necessary to undergo liver morphological and structural examinations as well as abdominal color Doppler ultrasound at a hospital, and proceed with further treatment under medical guidance.
