What is the difference between type 1 and 2 diabetes? I've heard that type two is a result of lifestyle and type one is inherited. Is this true? Are you born with type one? What are the different symptoms, and what are the different treatments? Is one more serious than the other?
Type 1 diabetes (t1D) is an autoimmune condition where the immune system kills of the cells in the pancreas that make insulin. It used to be called 'Insulin Dependent Diabetes Mellitus' (IDDM). People with t1D require insulin for the rest of their life. About 10% of people who live with diabetes have t1D.
Type 2 diabtets (t2D) is considered a 'lifestyle' disease. There are a couple of different theories. One is that overweight and obesity 'wears out' the pancreas, it can't make enough insulin. The other theory is that both dietary fat and body fat interfere with insulin uptake. The body makes lots of insulin, but can't use it. Insulin causes weight gain, so there poor people are in a vicious circle. About 85% of people who live with diabetes have t2D.
