Diabetes mellitus is a chronic disease that develops due to absolute or relative insulin deficiency. Lack or of insulin, or inability of the body tissues to properly use insulin causes the rise in blood glucose levels – hyperglycemia, which is dangerous for almost all body systems.
There two types of diabetes:
Type 1 diabetes results from the pancreatic cells failed to produce the sufficient amount of insulin.
Type 2 diabetes results from the body’s resistance to insulin produced.
