Which of the following short-term weight loss devices can be used for up to 12 months?

The TransPyloric Shuttle is designed as a temporary weight loss device that can be used safely for up to 12 months. It functions by sitting in the stomach and physically promoting early satiety and delaying gastric emptying. The use of this device is specifically tailored for short-term weight management, providing a means for patients to potentially adjust their habits and engage in lifestyle changes within that year.

Other weight loss devices have varying durations for use. For instance, the gastric band is a permanent procedure that can be adjusted but is not considered a temporary solution like the TransPyloric Shuttle. The same applies to adjustable gastric banding, as it is intended for long-term use. The gastric balloon, while also a temporary device, typically has a maximum usage period of around six months, thus falling short of the 12-month duration specified in the question. The distinct characteristics and intended use of the TransPyloric Shuttle make it the appropriate choice when considering short-term weight loss devices that can be used for an extended duration of up to 12 months.
