Diabetes mellitus type 1 is caused by insufficient or non-existent production of insulin, while type 2 is primarily due to a decreased response to insulin in the tissues of the body (insulin resistance). Both types of diabetes, if untreated, result in too much glucose remaining in the blood (hyperglycemia) and many
The following outline is provided as an overview of and topical guide to diabetes mellitus (diabetes insipidus not included below): Diabetes mellitus – group of metabolic diseases in which a person has high blood sugar , either because the pancreas does not produce enough insulin , or because cells do not respond properly to the insulin that ...

[ 10 ] [ 11 ] Diabetes is due to either the pancreas not producing enough insulin , or the cells of the body becoming unresponsive to the hormone's effects. [ 12 ]
Diabetic neuropathy can affect any peripheral nerves including sensory neurons, motor neurons, and the autonomic nervous system.

Obesity has been found to contribute to approximately 55% of cases of type 2 diabetes; [10] chronic obesity leads to increased insulin resistance that can develop into type 2 diabetes, [11] most likely because adipose tissue (especially that in the abdomen around internal organs) is a source of several chemical signals, hormones and cytokines, to other tissues.
Diabetic coma is a medical emergency in which a person with diabetes mellitus is comatose (unconscious) because of one of the acute complications of diabetes: [24] [25] Severe diabetic hypoglycemia Diabetic ketoacidosis advanced enough to result in unconsciousness from a combination of severe hyperglycemia , dehydration and shock , and exhaustion
In diabetes mellitus, hyperglycemia is usually caused by low insulin levels (diabetes mellitus type 1) and/or by resistance to insulin at the cellular level (diabetes mellitus type 2), depending on the type and state of the disease. [37]
