Private Bariatric Surgery

Revision Surgery in the UK

Are you unhappy with the results of your last bariatric surgery? Perhaps you went abroad and didn’t receive any aftercare, or have simply experienced weight regain. Either way, the medical weight loss specialists at Allure can help. Discuss revisional surgery with our team in order to fully explore your options. 

Don’t settle for unsatisfactory providers or service. Allure Weightloss is CQC registered with surgeries across England. Our team regularly perform gastric sleeves and gastric bypasses. We also have a renowned aftercare service with every procedure. 

Due to previously having had bariatric surgery your options may be limited, but in our experience it’s worth looking into. Weight loss is a journey, and we look forward to helping you on yours.

Types of Revision Surgeries:

Gastric Sleeve to Bypass Revisional Surgery


If you’ve had a previous sleeve gastrectomy, gastric sleeve, in the past, but have not been successful in your weight loss journey, we offer a revision procedure to revise the sleeve into a bypass.

Some people may regain weight and stretch a smaller, sleeved stomach over time. The best surgical option for these patients is to do a gastric sleeve revision and turn it into a gastric bypass. A gastric bypass doesn’t remove any of the stomach tissue, but instead our consultant surgeons create a new structure out of the existing stomach, commonly called a gastric pouch. This drastically limits the amount of food you can consume at any one time, limiting calorie intake and helping you to lose weight. Over a two-year period you can expect to lose up to 70% of your excess weight.

Gastric Band to Gastric Sleeve or Gastric Bypass


Gastric band patients who have not reached their desired weight loss goal or struggle with the maintenance of a gastric band may want a different option. We offer a revisional surgery to a gastric band or a gastric sleeve.

A gastric band or gastric sleeve surgery involves removing the gastric band and surgically altering the digestive system permanently. In order to determine whether it will be a gastric bypass or a gastric sleeve surgery, you will have an in-depth discussion with our consultant surgeon who will help determine which is most suitable.

A gastric sleeve revision procedure would involve removing the band completely and removing 80% of your stomach and suturing to create a smaller, banana shaped structure. This procedure is also known as a sleeve gastrectomy.

A gastric bypass revision surgery would involve removing the band and creating a new structure out of the existing stomach without removing any tissue. The new structure, often called a pouch, limits the amount of food you can eat at any one time.

Both procedures will significantly change the way you eat by limiting the amount of food that you can physically consume. By reducing the size of your stomach, it also suppresses the production of ghrelin (commonly referred to as the hunger hormone). The reduction of size and production of ghrelin can result in significant weight loss.
