Your Surgery Options
Feel confident in being provided with the best solution for your individual circumstances.
At your initial surgical consultation, together with your surgeon, you'll have the opportunity to discuss your eligibility for surgery and the type that suits you best.
Our aim is to provide you with all the information that you will need to make informed decisions about managing your health. You can read more about our surgery below. We are happy to address any further questions you may have regarding our surgery options, so please do not hesitate to contact us. We are here to help.

• To have tried other methods of weight loss, such as dieting, without long-term success.
-
• Reduces the physical space in your stomach - making you feel full from smaller portions of food.

• Most patients will not see the same weight loss results as those who are undertaking their first surgery
