Leptin receptor deficiency is a rare genetic disorder that affects the body’s ability to regulate appetite and weight. For patients and their families, the disorder seriously disrupts daily life, however, little is published about this impact. We here report the experiences of a 10.5-year-old girl with leptin receptor deficiency and her family. The diagnosis of this rare genetic obesity had a deep impact on the life of the child and her family. It led to a better underst...

Background: Paediatric obesity is a multifactorial disease characterized by an imbalance between energy intake and expenditure. In rare cases, obesity is caused by underlying medical disorders arising from disruptions in the leptin-melanocortin pathway, which regulates satiety and energy expenditure.Aim: To investigate resting energy expenditure (REE) in relation to body composition in children and adolescents with sever...

Introduction: In rare cases of obesity, genetic defects lead to hyperphagia and severe early-onset obesity. Genetic testing in patients with a suspected genetic obesity phenotype is important, as it can lead to patient-tailored treatment advice. For children, the Endocrine Society (ES) recommends genetic testing in children with early-onset of obesity (<5 years) and hyperphagia. It is unclear whether these recommendations can also be used in adult obesity c...
