Klinika Implications of Glucagon Suppression

By lowering glucagon, oral semaglutide reduces hepatic glucose production, which is te primary contror of fasting hyperglycemia. This effect complements its insulinotropic action, leading to improced overall glycemic control.

Non- glic fatty livear disease (NAFLD) is the mogt common chronic liver condition globaly, affecting up to 70% of patients with type 2 diastetes. It ranges from simple steatosis to non - crimelic steatohepatitis (NASH), which can progress to fibrowisis, cirrhosis, and hepatocellular carcomoma.
