Based on the previous reviews, most of the current obesity or weight management applications on the app stores are limited to the following: patient education, patient discussion forums, and weight management using hypnosis. There seemed to be a paucity of smartphone innovations and applications that could help individuals self-manage their weight issues. In contrast, conditions such as cystic fibrosis have applications that helped individuals self-manage their own conditions [11]. Conditions such as pain disorders also have smartphone applications that allow individuals to manage and monitor their own pain [12].

Taking into consideration previous literature, the team at TWH-BSP conceptualized and developed an aftercare application. The conceptualized application contains information about the various appointments, as well as information about routine blood works and vitamin supplementation. A user perspective survey was conducted after implementation and showed that the vast majority of patients felt that the information components of the application were useful, especially so with regard to the aspect of the application that provides information about each appointment. The vast majority of the participants also felt that the ability of the application to help them in rescheduling their appointment was also significantly helpful. Of importance, the introduction of the smartphone application has helped to change users’ perceptions and confidence about their ability to manage their own condition. After the implementation of the smartphone application, 25 % of the sample group reported being extremely confident about managing their own condition, as compared to 17 % prior [13].

With the rapid advances in technology, bariatric care , like other specialties, has been massively transformed by technological innovations. There are a multitude of bariatric-related applications in the smartphone stores currently. Prior research has highlighted the limitations of these smartphone innovations, in that most of them are lacking in evidence base. A recent analysis of the information quality of bariatric smartphone applications has also reinforced this viewpoint. It is the objective of this chapter to illustrate to healthcare professionals how advances in technology could be implemented successfully in promoting obesity self-management. In addition, the authors also wish to highlight how evidence-based approaches could be incorporated into bariatric applications could be incorporated into bariatric applications to better support patients and their providers in severe obesity care.
