Frequently Asked Questions

How much does weight loss surgery cost in New Zealand?

Weight loss surgery costs in New Zealand vary by procedure: gastric bypass ($20,000-$25,000), gastric sleeve ($18,000-$22,000), and gastric band ($15,000-$18,000). Costs depend on surgeon experience, hospital facility, and post-operative care. Some procedures may qualify for public funding.

Am I eligible for weight loss surgery?

Eligibility typically requires a BMI over 35 with obesity-related health conditions (diabetes, sleep apnea, hypertension), or BMI over 40. You must be aged 18-65, have tried non-surgical weight loss methods, and be psychologically suitable. A consultation with a specialist will determine your suitability.

How much weight can I expect to lose?

Most patients lose 60-80% of their excess weight within the first year, depending on the procedure and their commitment to lifestyle changes. Gastric bypass typically results in the most weight loss, followed by sleeve gastrectomy, then gastric band.

What is the recovery time?

Recovery varies by procedure: 2-3 weeks for gastric band, 3-4 weeks for sleeve, and 4-6 weeks for bypass. Most patients return to work within 2-4 weeks. Full recovery and adaptation to new eating habits may take 6-12 months.

What are the risks of weight loss surgery?

Weight loss surgery risks include infection, bleeding, blood clots, adverse reactions to anesthesia, and long-term nutritional deficiencies. Specific risks vary by procedure. Choosing an experienced bariatric surgeon significantly reduces these risks.

Will I need to change my diet permanently?

Yes, weight loss surgery requires permanent dietary changes including smaller portions, eating slowly, avoiding sugar and high-fat foods, and taking nutritional supplements. A dietitian will provide detailed guidelines for long-term success.

Does weight loss surgery cure diabetes?

Many patients with type 2 diabetes experience significant improvement or complete remission after weight loss surgery, particularly with gastric bypass. However, results vary by individual, and ongoing monitoring with your diabetes care team is essential.

Is weight loss surgery covered by insurance in New Zealand?

Public funding may be available for eligible patients through DHBs, typically requiring BMI >40 (or >35 with serious comorbidities) and meeting strict criteria. Wait times can be long. Private insurance may provide partial coverage depending on your policy.
