Diabetes (Diabetes mellitus)

A condition that occurs when the body cannot use glucose normally. Glucose (a type of sugar) is the main source of energy for the body’s cells.

The levels of glucose in the blood are controlled by a hormone called insulin, which is made by the pancreas. In diabetes, the pancreas does not make enough insulin (type 1 diabetes) or the body can’t respond normally to the insulin that is made (type 2 diabetes). This causes glucose levels in the blood to rise, leading to symptoms such as increased urination, extreme thirst, and unexplained weight loss.
