Can dropping pounds before hernia surgery boost outcomes?
NCT ID NCT05925959
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a weight loss program before complex hernia repair helps patients feel better a year later compared to having surgery right away. About 258 obese adults with large hernias will either join a weight management plan with diet, exercise, and medication, or go straight to surgery. The main goal is to see if upfront surgery is just as good for quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Preoperative Weight Management Program (lifestyle changes and anti-obesity medication)
- What this could lead to
- If successful, this could show that losing weight before hernia repair improves long-term quality of life and reduces complications.
- What could go wrong
- This is a mid-stage trial with 258 participants, so results may not apply to all patients. Weight loss programs can be hard to stick with, and some people may not lose enough weight to make a difference.

Inclusion criteria * Adults having open retromuscular ventral hernia repair with an anticipated posterior component separation with transversus abdominis release and synthetic mesh * BMI 40-55 kg/m2 and who are not planning to pursue weight loss surgery for any of the following reasons: they are not a candidate for weight loss surgery, cannot pursue weight loss surgery for insurance reasons, or are not interested in pursuing weight loss surgery. Exclusion criteria * Lack of English language fluency * Urgent need for repair as determined by surgeon judgement * Pregnant patients * Permanent stoma in place * Isolated flank hernia * Anticipated need for staged operation; for example, patients who will undergo a mesh excision separate from definitive reconstruction. * BMI \<40 or \>55 kg/m2 * Inability to participate in the Obesity Management Program due to lack of insurance coverage or history of mental illness (including eating disorders, schizophrenia, etc.). * Obstructive symptoms
