Gastric balloon overview

What is a gastric balloon?

This gastric balloon overview page can give you a summary of the procedure and what it involves.

A gastric balloon can help you reach your long-term weight loss goals. It is a non-surgical device that helps with weight loss. In this procedure, a surgeon puts a deflated balloon into your stomach via your food pipe. Once in the stomach, they will then inflate the balloon with salt water. The inflated balloon takes up around 1/3 of the stomach, meaning that you need to eat less food to feel full. This results in you losing weight as you start to eat less food overtime.

The balloon often stays in the stomach for 6-12 months. However, stomach acid damages the material over time and therefore it cannot stay in permanently.

Who can have a gastric balloon?

A gastric balloon provides an effective non-surgical option for patients struggling with weight loss. However, it is not suitable for everyone. It is most suitable for those who have a BMI of 28 to 35, and are prepared to make long-term changes to their diet and lifestyle.

As part of your assessment, your surgeon will want to discuss your motivations for weight loss and check your BMI. Furthermore, they may want to discuss other weight loss procedures that might be more suitable for you.

You may be suitable for a gastric balloon if you are looking to:

  • Lose weight before having another type of weight loss procedure, to help reduce the surgical risk
  • Want a non-surgical treatment for weight loss
  • Have a reversible weight loss procedure
  • Undergo a minimally invasive treatment that can be done with little interruption to daily life
