What helps the intra-gastric balloons increase satiety in patients?

Intra-gastric balloons are used as a non-surgical option for weight loss, and their primary mechanism for promoting satiety involves the physical presence of the balloon within the stomach. When the balloon is filled with saline, it occupies space in the stomach, which helps to create a feeling of fullness or satiety much sooner during meals. This sensation of fullness leads to a reduction in food intake, aiding patients in managing their weight.

Using saline is beneficial because it allows the balloon to conform to the shape of the stomach and can be adjusted for volume, if needed. Additionally, saline is safe for the body, making it a suitable choice for this purpose.

The other filling options, such as air or gas, do not provide the same level of gastric distension or safety. Air or gas can lead to discomfort or pain in the stomach, while food within the balloon is not practical or advisable for managing gastric space. Therefore, the choice of saline in intra-gastric balloons is crucial for effectively enhancing satiety in patients seeking weight loss solutions.
