What is diabetes?



Diabetes mellitus is a group of metabolic diseases characterized by high blood sugar (glucose)  levels, which result from defects in insulin secretion, or action, or both.





What are the different types of diabetes?


·         Type 1 diabetes is an auto-immune disease that develops when the body’s immune system destroys pancreatic beta cells—the only cells in the body that make the hormone insulin that regulates blood glucose. People with type 1 diabetes must take insulin every day either by injection or pump. Inhalable insulin is also available.

·         Type 1 diabetes accounts for 5% to 10% of all diagnosed cases of diabetes and usually affects children and young adults, although the disease can occur at any age. There is no known way to prevent type 1 diabetes.

·         Type 2 diabetes usually begins as insulin resistance—a disorder in which cells do not use insulin properly. As the need for insulin rises, the pancreas gradually loses its ability to produce it. Insulin resistance and abnormal beta cell function may occur long before type 2 diabetes is diagnosed.

·         Type 2 diabetes accounts for about 90% to 95% of all diagnosed cases of diabetes. It is associated with older age, obesity, family history of diabetes, history of gestational diabetes, impaired glucose metabolism, physical inactivity, and race/ethnicity. Although still rare, type 2 diabetes is being diagnosed more frequently in children and adolescents.
