Impact of Weight Loss Interventions on Multiorgan Health, Detected by Quantitative MRI, in Children and Young People With Severe Obesity.
The goal of this study is to quantify the body composition and organ fat distribution changes with obesity interventions in adolescents with severe obesity. The main question the investigators aim to answer is if there is improvement in organ health with weight loss intervention. The investigators will be comparing the degree of these changes between children being treated with GLP1 receptor agonists in addition to lifestyle changes and those managed with lifestyle changes alone. Participants will undergo MRI body composition at baseline and after 9 months.
