‘The whole process from start to finish with Mr Ahmed was amazing. He made me feel 100 per cent comfortable and confident in all my decision making. I managed to lose over 50 per cent of my body weight, I have zero scars from the surgery and he has completely changed my life and outlook towards food.'

Bariatric surgery and treatments

If you are looking to lose weight, our consultant bariatric surgeons will discuss your options with you and let you know what treatment is right for you.  

We offer several treatments, including non-surgical bariatric treatments, and weight loss surgery. All bariatric procedures are carried out using keyhole (laparoscopic) surgery as well as robotic surgery. 

Allurion Balloon

The Allurion Balloon is a swallowable gastric balloon that requires no surgery, endoscopy, or anaesthesia. When the balloon is swallowed and placed correctly in your gut, it helps to reduce your food intake by taking up space in the stomach and preventing you from feeling hungry.
