What symptom might indicate poor adherence to a diabetic regimen in an adolescent?

Persistent fatigue can be a significant symptom indicating poor adherence to a diabetic regimen in an adolescent. In individuals managing diabetes, effective adherence to their treatment plan is crucial for maintaining stable blood glucose levels and overall health. If an adolescent is not adhering to their regimen—whether it's related to medication, diet, or blood glucose monitoring—it can lead to fluctuations in blood sugar levels, resulting in symptoms like fatigue.

When blood glucose levels are not well-controlled, they can become too high (hyperglycemia) or too low (hypoglycemia), both of which can contribute to feelings of tiredness and lack of energy. Persistent fatigue can also signal that the body is not utilizing glucose properly due to poor adherence to the prescribed lifestyle changes or medication, further complicating diabetes management.

The other options reflect aspects related to health but do not specifically indicate poor adherence to a diabetic regimen. Stable blood glucose levels suggest effective management, regular exercise habits generally indicate a healthy lifestyle, and frequent weight gain might not directly correlate with adherence or might be due to other factors unrelated to the diabetes regimen.
