The liver mainly maintains the stability of blood glucose concentration through the process of synthesis and breakdown of hepatic glycogen. Hepatic glycogen is usually stored in the liver. When the blood glucose level rises after food intake, the excess glucose will synthesize glycogen and store it in the liver as hepatic glycogen, so that the blood glucose level will not become too high; when the blood glucose level drops, hepatic glycogen will decompose to produce glucose, which will then raise the blood glucose level and maintain the stability of blood glucose in the body. If liver function is impaired, abnormalities in the liver’s synthesis, storage and breakdown of glycogen may cause abnormal blood glucose levels. It is recommended that you seek medical attention if you have abnormal blood glucose levels or impaired liver function.
