Roughly there's about 300,000 people living with diabetes in Ireland and 90% of that is type two diabetes. And about 10% will be type one. Type 1 diabetes is an autoimmune condition where the body's immune system destroys insulin-producing cells, leading to a complete lack of insulin, while Type 2 diabetes is characterized by insulin resistance, where the body doesn't use insulin effectively, and the pancreas doesn't make enough insulin to compensate.
