Glucagon is what cells secrete

Glucagon is a hormone secreted by pancreatic islet alpha cells.

Glucagon secreted by pancreatic islet alpha cells has the effect of promoting liver glycogen decomposition and glyconeogenesis, which is conducive to maintaining stable blood sugar levels. The secretion function of pancreatic islet alpha cells is mainly affected by blood sugar concentration. In the case of low blood sugar levels, the function of pancreatic islet alpha cells is enhanced, and the secretion of glucagon is increased, but in any case, it is reduced.

If there is a high level of glucagon, daily physical exercise should be actively carried out to maintain a positive attitude to promote the return of glucagon levels to normal.
