Diabetes
Diabetes mellitus often referred to simply as diabetes is a syndrome of disordered metabolism, usually due to a combination of hereditary and environmental causes, resulting in abnormally high blood sugar levels (hyperglycemia).[2] Blood glucose levels are controlled by the hormone insulin made in the beta cells of the pancreas.[3] The two most common forms of diabetes are due to either a diminished production of insulin (in type 1), or diminished response by the body to insulin (in type 2 and gestational).[4] Both lead to hyperglycemia, which largely causes the acute signs of diabetes: excessive urine production, resulting compensatory thirst and increased fluid intake, blurred vision, unexplained weight loss, lethargy, and changes in energy metabolism.
