Benefits of Weight Loss Surgery

Transform More Than Just Your Weight

Bariatric surgery is about more than numbers on a scale — it’s about regaining your health, confidence, and quality of life. At Aurora Bariatrics, we focus on real, lasting change that helps you move, feel, and live better every day.



Your Options

Why Consider Weight Loss Surgery?

For many of our patients, weight loss surgery is the turning point after years of trying — and failing — to lose weight through diets, exercise, or medications alone. Surgery isn’t a last resort; it’s a powerful, evidence-based medical intervention that supports your body to reset, heal, and thrive.

When paired with our comprehensive aftercare program, bariatric surgery can:

  • Improve or reverse type 2 diabetes
  • Lower blood pressure and cholesterol
  • Reduce joint pain and inflammation
  • Improve sleep apnoea and increase energy
  • Support fertility and regulate hormones
  • Decrease the risk of certain cancers
  • Restore mobility, comfort, and independence
  • Enhance mental health and self-esteem


Health Gains That Last

Most patients lose between 65–85% of their excess weight within 12–18 months, depending on the type of surgery and their adherence to lifestyle changes. The real success isn’t just in the kilograms lost — it’s in how you feel, function, and live every day.

Our patients often report:

  • Travelling with ease and participating in family life
  • Wearing clothes that make them feel confident
  • Reducing or ceasing medications
  • Long-term improvement in chronic conditions
  • Feeling like themselves again

How Much Weight Will You Lose?

While weight loss results vary, our goal is to help you achieve a minimum of 60% excess weight loss. This level of weight loss typically leads to major improvements in weight-related health conditions.


Expected Weight Loss:

  • Sleeve Gastrectomy: Most reach goal weight by 12 months
  • Gastric Bypass: Most reach goal weight by 18 months

Average loss is between 0.5–2kg per week, depending on your starting weight

Outcomes also depend on your:

  • Age, sex, build and body composition
  • Commitment to healthy eating, activity, and lifestyle changes


Note: Up to 20% of patients may not reach the minimum 60% target. Your surgeon will discuss the most appropriate procedure and expected results for your unique situation.

It’s Not About Willpower — It’s About Tools and Support

We know obesity is a complex, chronic condition influenced by genetics, hormones, and the environment. That’s why we don’t ask, “Have you tried dieting?” — because we know you already have.

Instead, we provide:

  • Evidence-based medical solutions
  • Personalised surgical options
  • A dedicated team including your surgeon, bariatric GP, dietitian, nurse practitioner, and allied health providers



A Pathway Designed for Women

Aurora Bariatrics specialises in supporting women navigating PCOS, menopause, metabolic disease, and hormone imbalances. We also offer guidance for those planning a pregnancy, including safe timing and nutrition advice after surgery.

Sleeve vs Bypass: Which Procedure Is Right for You?

We offer two of the most effective procedures:

Each has unique benefits depending on your health, goals, and lifestyle. Dr Blackham will help you choose the safest and most effective option for you.


Sleeve Gastrectomy Gastric Bypass
Expected Weight Loss 65–75% of excess weight within 12 months 70–85% of excess weight within 12–18 months
Best Suited For Patients seeking a simpler option with fewer absorption issues Patients with type 2 diabetes, reflux, or previous failed bariatric surgery
Hormonal Benefits Reduces ghrelin (hunger hormone), leading to appetite control Alters gut hormones to improve insulin sensitivity and regulate hunger
Nutrient Absorption Mostly preserved — fewer vitamin and mineral deficiencies Partial malabsorption — requires lifelong supplements and monitoring
Reflux/Heartburn May worsen or trigger reflux in some patients Typically improves reflux symptoms, especially with Roux-en-Y
Surgical Complexity Shorter operation with no intestinal rerouting More complex — involves creating a small pouch and rerouting the intestines
Hospital Stay Usually 1–2 nights Usually 2–3 nights
Recovery Time 2–4 weeks 2–4 weeks
Long-Term Maintenance Lower risk of complications long-term; fewer dietary restrictions Excellent metabolic outcomes, but requires strict adherence to supplements and follow-up care

It’s Not a Shortcut — It’s a Fresh Start

Weight loss surgery won’t do the work for you — but it does reset your metabolism, regulate hunger hormones, and help you build a new foundation for lifelong health. With the right support, change is not only possible — it’s sustainable.

It’s your story. We’re just here to help you write the next chapter — one with better health, energy, and freedom.
