The role of the pancreas in type 1 and type 2 diabetes is clear. In type 1 diabetes:
  • The immune system destroys the pancreas's beta cells, which means the body can no longer produce insulin.
  • This leaves people with type 1 in need of insulin in order to survive.
In type 2 diabetes:
  • The pancreas still produces insulin, but the body doesn't respond to the insulin as it should. This causes insulin resistance.
  • When there is insulin resistance, the beta cells of the pancreas's islets can no longer keep up with the body's demand for insulin and lower blood glucose levels as it should.
