Revisional Bariatric Surgeries
What is this procedure?
Revisional surgery is a secondary procedure performed to either improve weight loss outcomes for morbidly obese patients or to address complications from a previous bariatric surgery. It is commonly used to revise surgeries like Gastric Banding or Gastric Bypass, especially for patients who initially underwent a Gastric Sleeve procedure.
Who is it recommended for?
- Experienced weight regain or inadequate weight loss with previous surgery
- Have new or worsening medical issues
- Are suffering from complications of your original procedure
- Are committed to lifestyle changes and follow-up care
Advantages of the Surgery
- Minimal Scarring
- Faster Recovery
- Enhanced Weight Loss
Types of Revisions:
- Sleeve Gastrectomy Revision : If you're not losing enough weight or have acid reflux after a sleeve, it may be converted to a gastric bypass or corrected.
- Gastric Bypass Revision : For weight regain or issues like dumping syndrome, your bypass may be repaired or adjusted.
- Duodenal Switch Revision : If you’ve had weight regain or low nutrient levels, your duodenal switch can be revised to improve results.
- Pouch or Stoma Adjustment : If your stomach pouch has stretched, it may be tightened to restore portion control.
- Conversion to Duodenal Switch (BPD/DS) : If a previous surgery like a band or sleeve didn’t work well, it can be converted to a more effective option like the duodenal switch.
Nutrition Care Plan for Pre- and Post-Bariatric Procedure
Before your surgery, a 7-day liquid diet is advised . This helps shrink the liver and prepare your body for a safe procedure.
Post-Surgery:
A structured reintroduction of food is followed:
- Week 1-2: liquids and protein-rich fluids
- Week 3-4: Soft and semi-solid foods
- Week 4 onwards: Transition to a customized solid diet plan
This phased approach ensures healing, minimizes complications, and supports sustainable weight loss.
What is recovery like after a revision?
- Hospital stay: 1–3 days depending on the procedure
- Return to work: Usually 2–4 weeks
- Follow-up: Frequent early follow-up with lifelong annual check-ins
Will my nutritional needs change after revision surgery?
Yes. Revisional surgeries often involve more malabsorption, which means you’ll need:
- Lifelong vitamin and mineral supplements*
- Higher protein intake
- Close monitoring with bloodwork.
*Your exact needs depend on your procedure and lab values.
How can I prevent weight regain after revision surgery?
To protect your results long term:
- Avoid grazing and frequent snacking
- Eliminate liquid calories (sugary drinks, alcohol)
- Prioritize protein at every meal
- Track portions—even with restriction, it’s possible to overeat
- Work with your dietitian and support team regularly
