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.
