Which type accounts for over 90% of diabetes cases and is usually associated with overweight and lifestyle factors?

• A. Type I diabetes (insulin dependent)
• B. Type II diabetes (non-insulin dependent)
• C. Gestational diabetes
• D. Prediabetes

Answer: (B)

The key idea is that type 2 diabetes makes up the vast majority of cases and is closely linked to overweight and lifestyle factors. In this form, the body's tissues become resistant to insulin, and the pancreas cannot keep up with the demand by producing enough insulin, so blood glucose rises. Because of excess weight, physical inactivity, and dietary patterns, this type tends to develop in adults (and increasingly in younger people) and accounts for over 90% of diabetes cases. The situation is often managed first with lifestyle changes—weight loss, more activity, healthier eating—and medications like metformin as needed. By contrast, type 1 diabetes is caused by autoimmune destruction of the insulin-producing cells and is not mainly driven by overweight; gestational diabetes occurs during pregnancy; and prediabetes is a state of impaired glucose regulation that increases risk for diabetes but is not itself diabetes.
