If failure is defined as an inability to ameliorate comorbidities or prevent their recurrence, gastric bypass appears to have a failure rate of approximately 20%. Failure rates based on weight loss are controversial.

The overall failure rates for malabsorptive procedures are relatively low, although the need for reversal of the surgery because of resulting adverse effects appears to be relatively high.
