Gastric Sleeve & Gastric Bypass Surgery

Weight Loss Surgery (bariatric surgery) is the only scientifically proven method for long term and effective weight loss. Bariatric surgery is not a quick-fix cure.  Weight loss still depends on healthy eating and exercise, which is why OWLS has set up a support network to help patients on their journey.

OWLS patients not only achieve weight loss, but often see a reduction in many obesity related conditions such as type II diabetes, sleep apnoea, joint pain, lipid abnormalities and high blood pressure – these are either completely resolved or substantially improved.


Recovery varies between patients. For a gastric balloon we typically see patients recover after three days, for bariatric surgery it can take a week or longer and patients are closely managed. We like to see our patients take their time to heal and recuperate after any weight loss procedure.

We encourage OWLS patients to stay in hospital for as long as they need to ensure they are comfortably back on their feet again. We offer modern private en-suite rooms, with wifi, sky TV, and fresh meals prepared onsite. You can speak to your surgeon about how much time you will need.
