Final answer:
Type 2 diabetes occurs when body cells are no longer sensitive to insulin, leading to high blood sugar levels. It is typically developed in adulthood, but is now becoming increasingly prevalent in teens and children due to poor diet and lack of exercise. Being overweight and having high blood pressure are risk factors for type 2 diabetes.
Step-by-step explanation:
Type 2 diabetes occurs when the body cells become resistant to insulin, a hormone that helps take up sugar from the blood. While the pancreas may still produce insulin, it is not used efficiently by the cells. This type of diabetes is usually developed in adulthood, but it is becoming more common in teens and children due to the high prevalence of overweight individuals who have a diet high in sugar and fat. Being overweight and having high blood pressure increase the chances of developing type 2 diabetes.
