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

  • Short-term usage of the Intensive phase of the OPTIFAST VLCD Program has been shown to produce effective weight loss and improve health outcomes, and is associated with good adherence to treatment. Pre-operative weight loss does not appear to adversely affect immune function or wound healing.
  • OPTIFAST VLCD may also be required post bariatric surgery once a patient moves on from clear fluids to full fluids. Using OPTIFAST VLCD post-surgery will provide additional protein, vitamins and minerals. Three OPTIFAST VLCD shakes could be taken daily in place of meals. This will ensure all nutritional requirements are met but low enough in calories to assist with weight loss.
