What is the difference between Type 1 and Type 2 diabetes?

People with Type 1 diabetes must take insulin, people with type 2 often do not have to.

Type 1 diabetes is caused by lack of exercise while Type 2 is caused by obesity.

In Type 1 diabetes the body produces too much insulin, in Type 2 it produces too little.

People with Type 1 diabetes are often referred to as adult onset diabetics while people with Type 2 diabetes are often referred to as juvenile diabetics.
