Frequently Asked Questions
As a general guide, you are eligible for gastric sleeve surgery if you have a BMI of 35kg/m2 or over, and have exhausted other option without success.
As with all surgical operations, there are associated risks and a gastric sleeve is a more invasive procedure than a gastric band which is why it is important to choose a specialist bariatric surgeon with considerable gastric sleeve experience. In the hands of a highly experienced Healthier Weight surgeon, the gastric sleeve is still a safe and effective procedure. Read more about our sleeve centres and surgeons here.
Prior to gastric sleeve surgery, you will be required to follow a low-calorie pre-operative diet. The length of time that you will follow the pre-op diet will depend on your starting BMI and will range from a minimum of 5 days for lower BMIs, up to a maximum of 6 weeks for higher BMI.
Sleeve surgery is performed laparoscopically (keyhole) and takes approximately 45-60 mins. Patients usually stay in a hospital for 2 nights.
It is common to experience some discomfort after gastric sleeve surgery. The pain will mainly tend to be from the abdomen, but you may also experience some mild left shoulder pain as a result of the gas (carbon dioxide) that is used to inflate the abdomen during the operation. However, whatever discomfort you do experience is usually quickly alleviated by simple painkillers.
No, the gastric sleeve is not a reversible procedure as 80% of the stomach was removed during the original procedure. It can, however, be converted to a different procedure if required. A sleeve can be converted into a gastric bypass or could be combined with a gastric band.
