Q1. What is diabetes primarily characterized by?
- A. High blood pressure
- B. High blood sugar levels ✓
- C. Low blood sugar levels

- A. Slow healing wounds
- B. Weight loss ✓
- C. Blurred vision
- D. Fatigue
Why: Weight loss is more commonly associated with type 1 diabetes because the body starts breaking down fat and muscle for energy when insulin is not available.
