Surgical intervention by way of bariatric surgery can result in substantial weight loss that is sustained over the long term when combined with education, ongoing monitoring and patient support. However, features of severe obesity can increase the complexity of the bariatric surgical procedure and may increase the risks of surgery.
Pre-operative weight loss is therefore desirable to optimise the safety of surgery in obese patients scheduled for bariatric surgery, in particular by
reducing liver size which reduces the risk of conversion from laparoscopic to an open procedure. Pre-operative weight loss can also improve respiratory mechanics and biochemical factors associated with obesity, reduce the severity of co-morbidities and minimise operating recovery times. Importantly, weight loss prior to surgery sensitises the patient to the potential benefits of complying with post-operative dietary restrictions. Pre-operative weight loss prior to obesity surgery can be achieved rapidly and safely using a very low calorie diet such as OPTIFAST VLCD.
The Intensive phase of the OPTIFAST VLCD Program replaces normal dietary intake while maintaining sufficient quantities of
