How do intra-gastric balloons facilitate weight loss?

Intra-gastric balloons facilitate weight loss primarily by promoting earlier satiety. When the balloon is inserted into the stomach and inflated, it takes up space within the gastric cavity. This increased volume signals the stomach to communicate to the brain that it is full, leading to a sensation of fullness or satiety after consuming smaller amounts of food. This mechanism helps individuals reduce overall food intake, which can contribute to weight loss.

By focusing on creating a feeling of fullness, intra-gastric balloons assist patients in managing their eating behaviors and can complement lifestyle changes, such as dietary modifications and increased physical activity. The effectiveness of the balloon in promoting satiety is one of the key reasons it is considered a non-surgical weight management option.

The other options do not accurately describe the primary functions of intra-gastric balloons. They do not enhance metabolism or improve nutrient absorption, nor do they directly target hunger hormones, although reduced intake of food due to early satiety may have downstream effects on hunger regulation over time.
