We fully understand at Ashford and St. Peter’s that taking the decision to have surgery, to help with weight loss, is a major decision.

The clinical teams at our hospitals, located in Chertsey (Surrey) and Ashford (Middlesex), are dedicated to your healthcare and treatment.

In appreciation of this, we have designed these pages to inform you of the different types of surgery available, but also what you can expect on your visits.
