What Is a Gastric Balloon?

A gastric balloon is a non-surgical, temporary weight loss tool that helps you lose weight by reducing your stomach’s capacity. It’s designed for people struggling to lose weight through diet and exercise alone, but who may not want or need surgery.

How Does It Work?

  • The balloon is placed in your stomach—either by swallowing a capsule (like the Allurion Balloon) or via a quick endoscopic procedure (like the Spatz3 Balloon).
  • The balloon is inflated with saline, making you feel fuller with smaller meals.
  • It stays in place for 4 to 12 months, after which it’s removed endoscopically or passes naturally (depending on the balloon type).
  • During this time, you work with medical professionals to develop healthier eating habits and lose weight sustainably.

Key Benefits of a Gastric Balloon:

  • Non-surgical & minimally invasive
  • No permanent changes to your stomach
  • Quicker recovery compared to surgery
  • Helps you lose 10-15% of your body weight
  • Develops healthier eating habits

What Is Weight Loss Surgery?

Weight loss surgery, also known as bariatric surgery, involves permanent or semi-permanent changes to your digestive system to help with long-term weight loss.

Common Types of Weight Loss Surgery:

  1. Gastric Sleeve:
    • 80% of the stomach is removed, reducing the amount you can eat.
    • Permanent and generally results in significant, long-term weight loss.
  2. Gastric Bypass:
    • The stomach is reduced and rerouted, limiting food intake and reducing nutrient absorption.
    • Known for dramatic weight loss but is more complex.

Key Benefits of Weight Loss Surgery:

  • Significant, long-term weight loss (25-40% of body weight)
  • Improves obesity-related conditions like diabetes, high blood pressure, and sleep apnoea
  • Permanent results (for gastric sleeve and bypass)
  • Better for individuals with a BMI over 35
