After administering insulin, which finding is most indicative of effective glycemic control?

Consistent fasting blood sugar levels are a key indicator of effective glycemic control after administering insulin. Maintaining blood glucose levels within a targeted range is crucial for preventing both short-term complications, such as hypoglycemia and hyperglycemia, as well as long-term complications associated with diabetes management.

When fasting blood sugar levels are stable and within the normal range, it signifies that the insulin dosage has effectively managed blood glucose levels. This should be monitored regularly, as inconsistent or high levels would suggest inadequate glycemic control. Other factors like increased energy levels, stable weight, and normal appetite can be influenced by multiple other factors including diet, lifestyle, and individual metabolism, making them less direct indicators of effective glycemic control. Therefore, monitoring for consistent fasting blood sugar levels provides a clear measure of how well the insulin therapy is functioning.
