Why Surgery?

It is known conventional weight loss measures often result in a 10% loss of initial body weight.

Although this has been scientifically proven to lower cholesterol and death rates, for people with a BMI greater than 35 kg/m2, this still does not reduce your risk factors enough. With all types of surgery, we would expect the extra weight that you carry (your excess weight) to reduce by 50 – 70%, thereby helping medical conditions and improving your quality of life.


Which Surgery?

At Ashford and St Peters we currently offer the following operations:

  • Roux-en-Y gastric bypass
  • Sleeve gastrectomy
  • One Anastamosis Gastric bypass (also known as mini gastric bypass)

We hope to soon to also be able to offer Single anastomosis duodeno-bypass with sleeve gastrectomy (SADI-S)

All of our bariatric surgery is done laparoscopically (keyhole). Determining which surgery is best for you is always going to be difficult and will be dependent upon many things. Useful questions to consider when deciding are:


How much weight do I want to lose?

Realistically the Sleeve Gastrectomy can help you lose 50 – 60% of your excess weight, whilst a Gastric Bypass can result in 60 – 70% excess weight loss at 12 -18 months. However, it is not unknown for Sleeve patients to do just as well as Bypass patients.


How quickly do I wish to lose weight?

For most people with a Bypass and Sleeve gastrectomy, weight loss is immediate and quick for the first 6 – 9 months then slows and stabilizes between 12- 18 months after surgery.


How limited is the diet after the operation?

Due to the restrictive nature of all the surgical options, certain foods may cause difficulties. All should reduce your meal size. With a Bypass, there may be unpleasant side effects if you eat high sugar and fatty foods.


All operations involve making long term changes to your eating and lifestyle habits to ensure that surgery is successful.


What happens when I have been referred for Bariatric Surgery?

Once a referral has been received you will be invited to attend Group Forum. This informal group session is run by the Bariatric Specialist Nurse and the Bariatric Dietitian. The session consists of a presentation discussing the patient pathway, types of surgery, complications and pre and post-operative diets. Following the presentation you will be seen individually by the Bariatric Specialist Nurse where you will have your height and weight checked as well as being sent for an ECG and some blood tests. You will also be informed about who else you will be seeing during your assessment process.

It is IMPORTANT that you attend this appointment as this is your first step towards Bariatric Surgery. If you do not attend or arrange for an alternative date, you will not be able to progress further. Use your time in the Specialised Weight Management Service to research the surgeries so any questions you may have can be answered at the group forum.
