The bariatric service at the Whittington Hospital is known as the North London Obesity Surgery Service (or NLOSS). The Whittington Hospital has been providing bariatric surgery since 1998 and is one of the most established providers of such services in the UK.

At North London Obesity Surgery Service, we undertake gastric banding, Roux-en-Y bypass (gastric bypass) and sleeve gastrectomy. All operations are performed laparoscopically (keyhole surgery), which will help you to get up and around and back to normal as soon as possible after surgery.

At present we undertake up to six operations a week and will be performing greater numbers throughout 2010 as our service expands. One of the mainstays of the NLOSS is the multidisciplinary team. Each team member has his or her own role and all together we ensure you are fully informed about weight loss surgery and that your operation is performed in the safest possible environment. Your safety is our first priority.
