What is Diabetes Mellitus primarily a disorder of?

Diabetes Mellitus is primarily a disorder of pancreas function because it is directly related to the body's ability to produce and regulate insulin, a hormone secreted by the pancreas. In Diabetes Mellitus, the pancreas either does not produce enough insulin (as in Type 1 diabetes) or the body becomes resistant to the insulin that is produced (as in Type 2 diabetes). This disruption in insulin production and regulation leads to elevated blood glucose levels, which characterize the disorder.

Understanding the role of the pancreas is crucial in recognizing how diabetes impacts overall metabolism and blood sugar control, making the pancreas the central organ involved in the condition.
