What Is Type 2 Diabetes?

Type 2 diabetes is a chronic condition wherein the body either doesn’t produce enough insulin or the body’s cells become resistant to the insulin that is produced. Insulin helps the body process sugar (glucose) and turn it into energy. When a person has type 2 diabetes, their glucose levels become elevated and remain higher than normal (known as hyperglycemia). Type 2 diabetes is a non-communicable disease (NCD).
