If a patient's gastric emptying rate increases abnormally after bariatric surgery, which consequence on blood hormone levels is most likely?

💡 Explanation

GLP-1 secretion is typically stimulated by nutrients reaching the distal small intestine; because rapid gastric emptying delivers nutrients more quickly, it overwhelms the normal GLP-1 secretory response, causing a blunted release. Therefore, GLP-1 secretion amplitude diminishes, rather than insulin secretion decreasing directly or ghrelin increasing.
