Which factor is most likely to affect the effectiveness of insulin therapy?

The effectiveness of insulin therapy can significantly be influenced by the client's overall lifestyle and habits. This encompasses various aspects such as diet, exercise, stress management, and adherence to prescribed medication regimens. A balanced diet, regular physical activity, and maintaining a healthy weight can improve insulin sensitivity and glucose control, which are crucial for managing diabetes effectively. Additionally, lifestyle choices such as smoking or excessive alcohol consumption can further complicate diabetes management and affect how well insulin works in the body.

Though the type of insulin used, the time of day insulin is administered, and proper storage temperature are important factors, they are more technical aspects of insulin therapy. The individual's lifestyle choices, however, can have a profound and direct impact on metabolic health and how the body responds to insulin. Therefore, considering the comprehensive nature of diabetes management, client habits form a foundational element in determining the overall effectiveness of insulin therapy.
