Answer: d) "Let's try it. Your glycohemoglobin will be lowered and you may lose weight."
Explanation:
Dan can try Byetta since he is a type 2 diabetic, and Byetta is strictly for type 2 diabetes.
Byetta (Exenatide) is a man-made hormone injectible drug (incretin mimetics) which is used to treat people with type 2 diabetes. It helps lower blood sugar levels by increasing the secretion of insulin from the pancreas, which decreases the action of glucagon and slows down the absorption of glucose from the gut.
It reduces appetite, which is an advantage for Dan because it can help him achieve weight loss.
