Is weight loss surgery for you?

Being overweight or obese can have serious impact on both your physical and mental wellbeing. It can negatively affect your self-confidence and self-esteem and put you at increased risk for serious health conditions such as type 2 diabetes, cancer and heart disease. If you're still struggling to lose weight even after dieting and exercising, these types of treatments can help give you the extra boost you and your health need to help shed significant amounts of weight. We can help you choose the treatment that’s right for you, helping to give you the energy and self-confidence to enjoy a healthy life. And it's also been found that weight loss surgery really does help.


Why choose Spire for weight loss surgery?

Every year we transform the lives of more than 2,000 people who choose to have weight loss treatment with us. Our expert bariatric surgeons offer a range of obesity surgery procedures including gastric banding (gastric band), also known as lap banding, gastric bypass and gastric balloon insertion. We also offer sleeve gastrectomy and duodenal switch operations. We are also the only licensed UK provider outside central London to offer one of the newest types of gastric balloon treatment - Obalon. Obalon is the first swallowable gastric balloon, which once in the stomach is inflated to the size of an apple. The Obalon balloon works by making you feel fuller faster and by following a healthy, balanced diet at the same time, helps you achieve the best possible weight loss results. This innovative treatment is discreet and non-invasive and can be administered quickly and painlessly in as little as 30 minutes. Obalon is available exclusively with Spire Healthcare outside of Central London. It is not available on the NHS. Regardless of which weight loss treatment you have, dedicated before and after care teams look after you throughout your weight loss journey, from making that first decision, to providing ongoing weight loss support and advice long after surgery. Our weight loss surgery teams are headed up by consultant bariatric surgeons, all registered with the General Medical Council, and include specialist weight loss surgery nurses, physicians and dieticians. There’s no waiting time for treatment and we offer payment options that help put weight loss procedures within your reach.
