Purpose of Review <p>Cystic fibrosis is a chronic condition that has significant effects on the nutritional status of pediatric patients. Malnutrition is frequently encountered in this population and has been shown to contribute to poor pulmonary and overall disease outcomes. This article will provide an overview of the physiologic and psychosocial challenges toward attaining optimal nutrition in pediatric cystic fibrosis patients.</p> Recent Findings <p>Newer therapies such as CFTR modulators have played significant roles in improving the nutritional status of patients with cystic fibrosis. There is also a greater focus on becoming more aware of psychosocial and cultural barriers in the care of cystic fibrosis patients.</p> Summary <p>Many challenges exist in optimizing nutritional support including but not limited to the patient’s clinical manifestations and disease severity, caregiver ability, and access to care. Both gastrointestinal and non-gastrointestinal disorders lead to insufficient caloric intake, increased loss and metabolic needs, and micronutrient and macronutrient deficiency. Social factors including stressful patient and caregiver relationships and altered body image also contribute to poor nutritional status.</p>
