Which health complication is highly associated with uncontrolled diabetes over time?

1. Hearing loss

2. Vision impairment

3. Severe fatigue

4. Frequent headaches

The correct answer is: Vision impairment

Uncontrolled diabetes over time is highly associated with vision impairment due to a condition known as diabetic retinopathy. This is a complication that arises from damage to the blood vessels in the retina caused by high blood sugar levels. As diabetes progresses, prolonged elevated glucose levels can lead to changes in the retina, resulting in vision issues that can range from mild to severe, and in some cases, may cause blindness if left untreated. In addition to diabetic retinopathy, high blood sugar can also lead to cataracts and glaucoma, both of which further impair vision. Regular eye exams and monitoring for changes in vision are crucial for individuals with diabetes to prevent or mitigate damage. While other options like hearing loss, severe fatigue, and frequent headaches can occur in people with uncontrolled diabetes, they are not as directly correlated with diabetes as vision impairment is. Vision impairment is a well-documented and significant risk as diabetes progresses, emphasizing the importance of glycemic control in preventing long-term complications.
