FAQ’s

What is Body Mass Index or BMI?

Body mass index is way of adjusting for the fact that taller people will weight more than shorter people. It is associated with long term health, but does not take in to account the effects of gender, race, age or muscle mass.

How do I calculate my BMI?

BMI may be calculated by dividing your weight in metres by the square of yourt height in kilograms.  Alternatively it may be calculated using this form.

Am I a candidate for bariatric surgery?

If you have a BMI of greater than 35 kg/m², have struggled with weight over time, and have been unable to keep weight off through diet and exercise alone you may be a candidate for bariatric surgery.  There are also endoscopic treatments to assist with weight loss for people with a BMI of between 27 and 40 kg/m².  More information may be found here.

What are the pre-surgical requirements for weight loss surgery?

Weight loss surgery is safest and most effective as part of an integrated weight loss surgery program.  Here at Aspiring Bariatrics Laparoscopy and Endoscopy Limited we partner with other professionals to provide this comprehensive service.  The pre-surgical program usually includes:

  • Comprehensive nutritional assessment from a dietitian experienced in bariatric surgery
  • Full medical assessment
  • Laboratory studies (blood tests)
  • Diagnostic sleep testing (for sleep apnoea)
  • Pre-surgical anaesthetic assessment

Will my health insurance cover bariatric surgery?

Coverage for bariatric surgery in New Zealand varies between health insurers, with some covering part of the cost of an operation.  We encourage you to talk to your health insurer about this.

For those without insurance coverage, private financing options may be available.

Do I need a referral from my GP?

The decision to undergo weight loss surgery has important consequences for your overall long-term health.  At Aspiring Bariatrics Laparoscopy and Endoscopy Limited we strongly encourage you to talk to you GP about the pros and cons of surgery on your health.  If you or your GP have further questions please email us at enquiries@aspiringbariatrics.co.nz.

Do you provide adjustments for Laparoscopic Adjustable Gastric Bands

Although we no longer place adjustable gastric bands, we are happy to provide an adjustment service and to manage any complications from this operation.  If people have not been seen previously by Aspiring Bariatrics they will need a copy of their operation report from their original surgeon, and a barium swallow x-ray which we are able to organise prior to their first adjustment.  We can request a barium swallow on your behalf through Pacific Radiology in either Dunedin or Clyde, please click the links for further information about this procedure.
