Type 2 Diabetes (cont.)

What Is the Difference Between Type 1 and Type 2 Diabetes?

Type 2 diabetes (formerly called adult-onset or non-insulin-dependent diabetes) is the most common form of diabetes, affecting 90% or more of those with the disease. In type 2 diabetes, the body produces insulin but is unable to use it properly (a condition called insulin resistance). Initially, the pancreas compensates by making more insulin but as the disease progresses the insulin produced by the pancreas is no longer enough (a condition called insulin deficiency). Type 2 diabetes is preventable with a healthy lifestyle that includes a balanced diet, maintaining a healthy weight, and getting regular exercise.

In type 2 diabetes there may be no symptoms and the disease is typically diagnosed in adults, though children can have the illness. Those with type 2 diabetes do not experience episodes of low blood sugar levels (hypoglycemia), unless they are taking insulin or other anti-diabetic medications.

Type 1 diabetes (formerly called juvenile-onset or insulin-dependent diabetes) is an autoimmune disorder, in which the body's immune system attacks and destroys the cells that make insulin (beta cells).

In type 1 diabetes symptoms can be serious, and start in childhood or in younger adults. Low blood sugar episodes (hypoglycemia) occur frequently. Type 1 diabetes cannot be prevented.
