Metabolic and Bariatric Surgery in Adolescents: For Whom, When, and How?

Challenges and pitfalls of youth-onset type 2 diabetes

The incidence and prevalence of youth-onset type 2 diabetes mellitus (T2DM) are increasing. The rise in frequency and severity of childhood obesity, inclination to sedentary lifestyle, and epigenetic risks related to prenatal hyperglycemia exposure are important drivers of the youth-onset T2DM epidemic and might as well be responsible for the early onset of diabetes complications. Indeed, youth-onset T2DM has a more extreme metabolic phenotype than adult-onset T2DM, with greater insulin resistance and more rapid deterioration of beta cell function. Therefore, intermediate complications such as microalbuminuria develop in late childhood or early adulthood, while end-stage complications develop in mid-life. Due to the lack of efficacy and safety data, several drugs available for the treatment of adults with T2DM have not been approved in youth, reducing the pharmacological treatment options. In this mini review, we will try to address the present challenges and pitfalls related to youth-onset T2DM and summarize the available interventions to mitigate the risk of microvascular and macrovascular complications.

Long-term Outcomes Following Adolescent Metabolic and Bariatric Surgery

Severe obesity in adolescence negatively impacts upon health and wellbeing. Lifestyle modifications do not usually achieve a sufficient degree or durability of weight loss to mitigate the risk of medical complications. In recent years, metabolic and bariatric surgery (MBS), already a well-established treatment for adults with severe obesity, has emerged as an option in adolescents. Controlled studies in this age group have demonstrated substantial and sustained weight loss, improvements in associated health parameters, and a safety profile surpassing that observed in adult patients. This review aims to present published data on the results of MBS in adolescents with a focus on long-term outcomes. Indications for bariatric surgery and aspects of timing in the young person's life are also presented, along with safety considerations and factors influencing patient selection for surgery. We conclude, predominantly from short- to medium-term outcomes data, that MBS is a safe and valuable therapeutic option for adolescents with severe obesity. Considering the poor health and social wellbeing prognosis in this group, MBS appears to be underutilized. The need for continued research, multiprofessional specialist provision, coherent contemporary clinical guidelines, and routine long-term follow-up in adolescents undergoing MBS is highlighted.

Adolescents' and professionals' experiences of metabolic and bariatric surgery and requirements for preoperative and postoperative support through mHealth: a qualitative study

OBJECTIVES

This study aimed to explore adolescents' and professionals' incentives and experiences of metabolic and bariatric surgery (MBS) and to explore perceived needs and requirements for preoperative and postoperative support through an mHealth intervention to improve long-term healthy lifestyle behaviour and health outcomes.

DESIGN

An inductive qualitative study using in-depth semistructured interviews.

SETTING

Three hospital-based specialist paediatric obesity treatment units in Sweden.

PARTICIPANTS

A total of 18 participants (14 women and 4 men). Nine adolescents aged between 17 and 22 years who had undergone or were about to undergo surgery, and nine professionals, including researchers and clinicians working in various professional roles such as physiotherapist, dietician, nurse, psychologist, physician and pedagogue.

RESULTS

Both informant groups of participants highlighted that undergoing MBS is a complex process, and hence actions are required on several levels to optimise the positive, long-term effects of surgery. Efficient communication between the healthcare professionals and adolescents was considered crucial and a key success factor. Informants acknowledged the need for additional support that relates to psychosocial well-being and mental health in order to understand, form and accept new behaviours and identity. An mHealth intervention should be seen as complementary to physical appointments, and informants acknowledged that an app could be a way of improving access to healthcare, and a useful tool to allow for individually tailored and easily available support.

CONCLUSIONS

The findings address the importance of a personal encounter and a need for additional support that relates to psychosocial well-being, mental health and healthy lifestyle behaviour. These findings should be incorporated into future research concerning mHealth interventions in MBS during adolescence.
