Purpose of Review <p>Fatigue and sleep difficulties are known concerns in pediatric Inflammatory Bowel Disease (IBD). The assessment and treatment of these concerns in young people with IBD, aged 14 to 22 years old, are particularly nuanced given their emerging autonomy and responsibilities, changes in living situation (e.g., college dormitory), shifting circadian rhythms, and transitioning between pediatric and adult care. The current review summarizes the unique assessment and treatment needs for fatigue and sleep concerns in this population, and provides recommendations for optimal multidisciplinary care.</p> Recent Findings <p>Fatigue and sleep difficulties in adolescents and young adults with IBD are highly multifactorial. Despite the frequency of reported fatigue and sleep disturbance in this population, validated screening measures for these concerns specific to children and adolescents with IBD are not currently available. Long-term, collaborative multidisciplinary care is required to identify major drivers of fatigue and sleep concerns (e.g., inflammation, depressed mood, pain), as well as provide thorough assessment and ongoing treatment. Embedded psychologists serve an important role of the multidisciplinary team in the assessment and treatment of this patient population.</p> Summary <p>Adolescents and young adults with IBD have higher rates of fatigue and sleep difficulties than same-aged peers, with complexities to their multidisciplinary care related to their evolving autonomy, developmental bodily changes (e.g., circadian rhythms), and changes in medical care setting (e.g., transitioning from pediatric to adult care). Multidisciplinary care, including direct consultation with and referral to embedded psychologists when available, is recommended when assessing and treating fatigue and sleep difficulties in this population.</p>
