    Diabetes is a disorder of metabolism -- the way our bodies use digested food for growth and energy. There are three main types of diabetes: type 1, type 2, and gestational diabetes.

    What Is Diabetes?

    Diabetes is a number of diseases that involve problems with the hormone insulin. There is no cure for diabetes. People with diabetes need to manage their disease to stay healthy.


    There are three major types of diabetes: type 1 diabetes, type 2 diabetes, and gestational diabetes.


    An A-to-Z guide to the language of diabetes.


    Diabetes Insipidus

    The term "diabetes insipidus" has nothing to do with high blood sugar. Instead, it's a general term for any condition that causes your body to make a lot of urine.

    Most commonly known as gestational DI, gestagenic diabetes insipidus is a rare disorder that happens in pregnancy, usually in the third trimester.

    Central diabetes insipidus happens when the body doesn't make enough of the hormone vasopressin, which controls how much urine the kidneys put out. The key sign of the disease is extreme thirst and excessive urination.

    In nephrogenic diabetes insipidus, the kidneys can't respond to a hormone that regulates fluid balance. Excessive urination and thirst are the results.

    Blood Sugar

    See medical guidelines for blood sugar levels with diabetes.

    Blood sugar control is at the center of any diabetes treatment plan. High blood sugar, or hyperglycemia, is a major concern and can affect people with type 1 and type 2 diabetes.

    People with diabetes get hypoglycemia (low blood sugar) when their bodies don't have enough sugar to use as fuel. It can happen for several reasons, including diet, some medications and conditions, and exercise.
