â›ŗBasal Insulin and Fasting Blood Glucose

👉Fasting blood glucose (FBG) is primarily regulated by basal insulin secretion.

👍Basal insulin suppresses hepatic glucose production (gluconeogenesis and glycogenolysis) during fasting.

👍If basal insulin secretion is inadequate, the liver releases excessive glucose, causing an increase in fasting blood glucose.

Basal Insulin↓→Hepatic Glucose Output↑→Fasting Blood Glucose↑
