ABSTRACT
Type 2 diabetes mellitus (DM) is a syndrome of impaired metabolism caused by reduced insulin secretion or decreased issue sensitivity to insulin. Type 2 DM begins with sustained hyperglycemia causing insulin resistance. Hyperglycemia also causes ROS (Reactive Oxygen Species) increase, especially in pancreatic β cells eventually lead, to cell damage and more severe type 2 DM. Hypoxia has been obsewed can increase cell glucose transporserthrough activation of transcription factor HIF-1α (hypoxia Inducible Factor 1α), reducing hyperglycemia and preventing destruction of pancreatic β cells in diabetic patients with insulin resistance. Hypoxia also lowers oxygen in cells as a source of ROS. ROS decrease will reduce risk of pancreatic β cells damage in Type 2 DM. Hypoxia likely prevents further damage in type 2 DM by preventing pancreatic β cells destruction.
Key words: type 2 diabetes melitus. hypox a, parcreatic β cells
