Reasons for post-operative weight loss failure can include problems with the original surgery, as well as the patient’s inability to comply with necessary life style changes.
We work with patients who have already had weight loss surgery but are looking for another solution as their original surgery has not been a success, for whatever reason.
Preventing complications, managing complications and managing patients post operatively are all equally challenging aspects of care to us. We can offer one to one consultations to patients with post-surgery weight loss failure to discuss conversion surgery further.
Patients are screened carefully to determine cause of failure and are medically evaluated prior to any further surgery taking place.

There are several variations of a Gastric Bypass. The most common procedure in the UK is the Roux-en-Y, also known as RYGB. It is a combination of restrictive and malabsorptive procedures, therefore has a two-way weight reducing effect. A small pouch is created by stapling off a section of the upper part of the stomach. Below the staple line the stomach will remain but no food will enter here.
