Final answer:
The condition that may develop as a result of juvenile diabetes mellitus is blindness (D). This is due to damage to the blood vessels in the retina caused by high blood glucose levels, which can lead to diabetic retinopathy. Therefore, the correct option is D.
Step-by-step explanation:
Juvenile diabetes, also known as type 1 diabetes mellitus, is a condition where the pancreas fails to produce enough insulin due to the destruction of beta cells. This lack of insulin production leads to high blood glucose levels, which, if not properly managed, can result in various long-term complications. Among these complications, damage to the small blood vessels is significant because it can cause a series of health issues.
When considering the complications listed in the question, the correct answer is D. Blindness. High blood glucose levels can cause damage to the blood vessels in the retina of the eye, potentially leading to diabetic retinopathy and, eventually, blindness. This eye damage is one of the most common and severe consequences of diabetes, including juvenile diabetes. While other options listed may be symptoms or consequences of different conditions, they are not typically associated with juvenile diabetes.
