Frequently Asked Questions

Bariatric surgery includes a variety of surgical procedures designed to help people lose weight by making changes to the digestive system. The most common types are gastric bypass, sleeve gastrectomy, and adjustable gastric banding. These surgeries aid weight loss by restricting food intake, altering nutrient absorption, or a combination of both.

Candidates for bariatric surgery generally have a Body Mass Index (BMI) over 35 or over 30 with related health conditions like diabetes, hypertension, or sleep apnoea. A thorough evaluation with a healthcare provider is necessary to determine suitability.

Bariatric surgery can lead to significant weight loss and help improve or resolve obesity-related health conditions such as type 2 diabetes, high blood pressure, and sleep apnoea. It can also improve quality of life and longevity.

As with any major surgery, bariatric surgery has risks, including infection, blood clots, and potential complications related to anaesthesia. There are also procedure-specific risks, such as nutrient deficiencies or digestive issues. Your surgeon will explain the risks and steps to minimise them.

Some types of bariatric surgery, such as adjustable gastric banding, are reversible. Gastric bypass is potentially reversible. Reversing a gastric bypass, though, is a complex surgery and is only done in very selective scenarios like malnourishment. Therefore, we encourage our patients to think of it as a permanent operation. Sleeve gastrectomy is generally permanent. Discuss […]

Yes, bariatric surgery is available on the NHS for patients in the UK who meet specific criteria, including a BMI over 40 (or over 35 with serious health issues) and a history of unsuccessful weight loss attempts. Referrals typically come through a GP and may involve a waiting period.

After surgery, patients need to adopt a healthy diet, often starting with liquids and gradually moving to solid foods. Regular physical activity is also encouraged. Long-term success depends on maintaining these lifestyle changes.

Yes, bariatric patients are often prescribed specific vitamins and supplements due to changes in nutrient absorption. Common supplements include a multivitamin, calcium, vitamin B12, and iron. Your healthcare provider will guide you on this.
