What should Dan be advised about the use of exenatide for his type 2 diabetes?

Exenatide is a glucagon-like peptide-1 (GLP-1) receptor agonist used in the management of type 2 diabetes. It works by enhancing insulin secretion in response to elevated blood glucose levels, slowing gastric emptying, and reducing appetite, which can lead to weight loss. Therefore, advising Dan to try exenatide is appropriate as it may help lower his glycohemoglobin (HbA1c) levels, a key indicator of long-term blood glucose control.

The potential benefits include improvements in glycemic control and possible weight reduction, both of which are advantageous in managing type 2 diabetes. This aligns with the goals of diabetes treatment, which emphasize not only glucose control but also weight management, particularly since obesity is a common comorbidity in type 2 diabetes.

Considering the other choices, adjusting oral antidiabetic agents might be a consideration, but it does not provide the benefits of the direct action that exenatide offers. Suggesting that weight change is solely due to eating behavior overlooks the pharmacological effects of medications like exenatide, which are designed to assist with both glucose control and weight management. Lastly, stating that Dan should not use injectable insulin might imply a limitation on treatment options
