The risks and complications associated with a converted bariatric procedure can be more significant than the initial bariatric procedure. However, many patients will have lost a considerable amount of weight and improved many of the comorbidities associated with obesity, so from a health standpoint, patients are often in a better position to recover well from these surgeries.
Revision/conversion bariatric surgery requires a rigorous qualification process. We first evaluate the patient’s dietary and exercise habits to see if optimization can allow additional weight loss. GLP-1s, whether in injection or pill form, may also be tried. Only when all options are exhausted do we turn to a second surgery to correct any weight gain.
It is also important to understand that there will be some weight regain after any bariatric procedure as motivation to diet and exercise wanes in the years after surgery. Regaining five or even 10% of the prior excess weight loss is nothing to be concerned about and would not qualify a patient for a revision procedure. Instead, patients must be struggling with significant weight regain for this to be an option.
