What are common symptoms that may worsen during insulin adjustment periods?

The correct answer highlights that fluctuating blood glucose levels are a common symptom that may worsen during insulin adjustment periods. When a patient is undergoing changes in their insulin regimen—such as starting insulin therapy, changing dosages, or switching types of insulin—it's common for their blood glucose levels to experience variability. This fluctuation can be due to several factors, including the body's response to the new dosing, variations in diet, physical activity levels, and the timings of insulin administration.

During this adjustment stage, individuals may experience episodes of hyperglycemia (high blood sugar) or hypoglycemia (low blood sugar) more frequently as their bodies adapt to the new insulin levels, which can make blood glucose readings less stable overall. This emphasizes the importance of close monitoring during the adjustment period to ensure dosages are optimized and to prevent complications associated with unstable glucose levels.

The other options do not reflect the physiological changes that typically occur during insulin adjustments. For instance, an increase in energy and focus, a constant appetite, or reduced fatigue are not standard symptoms associated with the fluctuations in glucose levels during this time.
