Severe obesity in childhood is increasing in prevalence and is associated with considerable morbidity. Studies into pediatric obesity have focused largely on interventions that do not necessarily target the unique biologic or psychological underpinnings for the weight gain in the individual child or adolescent. Outcomes show modest improvement and are of questionable benefit for patients with severe obesity. Although weight is a commonly used outcome, other psychological and metabolic parameters including normalization of physical activity and eating behaviors should be primary outcome goals. The durability of weight loss is often limited by physiologic systems that are evolutionarily designed to promote weight gain. Drug therapies for children are limited, as is their effect on weight and metabolism. Existing drugs that are incidentally found to cause weight loss through off-target effects are being actively investigated for obesity indications. Bariatric surgery results in the most significant weight reduction, but it is associated with potential morbidity and long term data are not available for adolescents undergoing this procedure. As understanding of the biologic and psychosocial contributors to eating behaviors and body weight regulation increases, multifaceted and targeted behavioral, pharmacological, and surgical treatment algorithms should be developed and applied to target the underlying pathways involved for the individual child or adolescent with severe obesity.
