Do I Qualify?
There is no standard weight over which you become a suitable candidate for weight loss surgery. This is because the taller you are, the more weight you can safely carry.
To allow for this, we use a formula known as the Body Mass Index, or BMI for short. BMI is calculated by taking your weight in kilograms, divided by your height in metres. The answer is then divided a second time by your height in metres.
The upper limit of a healthy BMI is 25.
If your BMI goes over 40, this is a level of obesity known as morbid obesity which is strongly associated with serious health problems such as type 2 diabetes.
The lower BMI limit for surgery was set at 40 (or 35 if you had additional medical problems that can improve after weight loss) more than 20 years ago, at a time when all surgery was performed using traditional open techniques and many patients underwent operations that are now rarely performed. This has led some to call for a reappraisal of the BMI cut-off points for surgery, particularly as almost all surgery is now carried out using less invasive ‘keyhole’ laparoscopic techniques that have a safety profile similar to (or better than) that of many common general surgery operations such as hip replacement or gallbladder removal.
Phoenix Health support the recent trend to reducing BMI thresholds as our own clinical audit has shown surgery in lower BMI patients to be a safe option with considerable benefits.
It’s all about balancing the potential risks of surgery with its potential benefits.
We will provide you with a bespoke, detailed assessment of your personal surgical risk/benefit balance and if you wish to proceed, we will consider you for surgery (subject to a detailed medical assessment) if you have a BMI above 30 (above BMI 27 for gastric balloon).
