The liver plays a huge role in the regulation of blood glucose in the body. The liver maintains the blood glucose concentration relatively stable by storing glycogen, releasing glycogen and gluconeogenesis. 1. Glycogen storage: When blood glucose is high, the body will store the excess glucose, in the form of hepatic glycogen, in the liver, and the glucose in the serum will drop. 2. Glycogen release: When blood glucose is low, the liver releases hepatic glycogen into the blood to keep the blood glucose concentration stable. 3. Glycolysis: Glycolysis is the process of converting non-sugar substances in the body into glucose and glycogen. Under starvation, when the source of glucose in the body is insufficient, the role of hepatic gluconeogenesis is strengthened, and the liver can convert amino acids, fats and other substances into glucose to ensure the relative stability of blood glucose. The liver is a key organ in maintaining constant blood glucose, and impaired liver function may affect glucose metabolism and lead to fluctuations in blood glucose.
