Type 2 diabetes occurs when the body no longer produces enough insulin or has difficulty using the insulin it produces, causing sugar to build up in the blood. Over time, if uncontrolled, this damages blood vessels and nerves and can result in severe complications including: blindness, heart disease, stroke, kidney failure, nerve damage, amputation, and erectile dysfunction. Adopting a healthier lifestyle can help prevent or control type 2 diabetes and can significantly reduce your risk of heart disease and stroke. It can also contribute to your overall well-being and quality of life.
