There are several types of gastric balloons used in weight loss procedures, and each differs slightly in design and method of placement. As of my knowledge cutoff in September 2021, the three most commonly used types of gastric balloons were: Orbera Intragastric Balloon The Orbera balloon is a single sphere that’s inserted into the stomach through the esophagus. It’s then filled with a saline solution. This balloon stays in place for about six months before being removed. ReShape Duo Balloon This device consists of two connected balloons. Like the Orbera, it’s inserted through the esophagus and filled with a saline solution. The ReShape Duo provides a feeling of fullness but may conform better to the shape of the stomach due to its two-balloon design. Obalon Balloon System The Obalon system is unique because the balloons (up to three) are swallowed in the form of a pill, then inflated with gas once they’re in the stomach. The Obalon balloons are left in the stomach for six months. Allurion Elipse Balloon The Allurion Elipse Balloon is unique as it requires no endoscopy for placement or removal. Instead, it is swallowed like a pill and then filled with fluid. After about four months, the balloon opens and is naturally passed from the body. In addition to these, there’s a newer type of balloon called the Elipse Balloon, which does not require endoscopy for placement or removal. It’s swallowed like a pill and filled with liquid. After about four months, it opens and passes naturally from the body. The choice of the appropriate gastric balloon depends on many factors, including your personal health goals and the recommendation of your doctor. It’s crucial to explore all options and seek extensive consultation to make the best decision.
