Diabetes mellitus is a combination of several diseases with various etiologies. Each one of these diseases have one thing in common, high blood glucose level thanks to insufficient secretion of insulin from the cells of the Langerhans islets in the pancreas. This high blood glucose results in the symptoms of polyuria (frequent urination), polydipsia (increased thirst) and polyphagia (increased hunger).
High Blood Glucose (Sugar)
High blood glucose (sugar) develops when your body has inadequate insulin or if your body cannot use insulin properly. It is also called Hyperglycemia. Short-lived hyperglycemia is usually harmless and asymptomatic. Blood glucose (sugar) levels can surge well above normal for substantial time periods without creating any long term effects or symptoms.
