Weight Loss Predictor

Your final weight loss after bariatric surgery depends on a combination of factors, including:

• Your body build and composition
  
• Sex and age
  
• Starting weight
  
• Type of surgery performed

Just as importantly, your long-term results are influenced by your ability to make and maintain lifestyle changes, such as:

• Adopting healthy dietary habits
  
• Staying physically active
  
• Following your post-surgery care plan
  

Typical Weight Loss Timelines

Every patient’s journey is unique, but most follow these general patterns:

• Sleeve Gastrectomy – Many patients reach their goal weight within 12 months
  
• Gastric Bypass – Many patients reach their goal weight within 18 months
  

This usually means losing 0.5kg to 2kg per week, depending on your starting weight and adherence to your program.

Why We Aim for at Least 60% Excess Weight Loss

At Aurora Bariatrics, we set a minimum goal of achieving 60% excess weight loss.
Research shows that this level of weight reduction offers the maximum improvement in weight-related health conditions, such as:

• Type 2 diabetes
  
• Sleep apnoea
  
• High blood pressure
  
• Joint pain
  

However, it’s important to note that up to 20% of patients may be “non-responders” — meaning they don’t reach the 60% target. Your surgeon will help you choose the best surgical option to maximise your chance of success.
