Hormonal

Malabsorptive bariatric surgery (BPD) reverses type 2 diabetes within 1-4 weeks by normalizing peripheral insulin sensitivity and enhancing beta-cell glucose sensitivity, independent of significant weight loss.

For morbidly obese individuals with type 2 diabetes, malabsorptive bariatric surgery (like BPD) can reverse the disease within weeks, largely by improving how the body uses insulin and how the pancreas responds to glucose, rather than just through weight loss. This suggests that surgical alteration of gut anatomy has a direct hormonal impact on diabetes.

BPD determines a prompt reversibility of type 2 diabetes by normalizing peripheral insulin sensitivity and enhancing beta-cell sensitivity to glucose, these changes occurring very early after the operation.
