Which statement describes a potential complication of Type 2 diabetes?

• A. Obesity is a factor
• B. Can cause blindness and kidney damage
• C. Insulin no longer effective
• D. Too much sugar

Answer: (B)

Chronic high blood glucose in Type 2 diabetes can damage small blood vessels, leading to complications like diabetic retinopathy (which can cause blindness) and diabetic nephropathy (which can cause kidney damage). This makes the statement describing blindness and kidney damage a true and direct description of possible complications. Obesity is a risk factor that increases the chance of developing Type 2, but it isn’t a complication of the disease itself. Saying insulin is no longer effective isn’t a precise description of a complication—insulin resistance and the need for treatment can vary, and insulin can still be used effectively in many people. Too much sugar describes a dietary factor, not a direct long-term complication.
