Which mechanism explains why bariatric surgery, altering gut hormone secretion, often results in improved glycemic control in type 2 diabetes patients?

💡 Explanation

Bariatric surgery improves glycemic control because it increases the secretion of GLP-1, which enhances insulin secretion and sensitivity, thereby lowering blood glucose levels. Therefore, increased GLP-1 is key, rather than reduced glucose uptake or induced insulin resistance, which would worsen glycemic control.
