Background/Objectives: Food protein-induced enterocolitis syndrome (FPIES) is a food-related hypersensitivity disorder characterized by delayed repeated vomiting that typically presents within the first years of life. Although FPIES has traditionally been considered a pediatric condition, it has more recently been observed also in teenagers and adults. Adult FPIES may be a continuation of childhood-onset disease or new-onset forms developing later in life. This review aims to describe the peculiarities of FPIES across the lifespan and to provide an update from the last years on the studies focused on FPIES in adolescence. Methods: Papers focusing on FPIES in adolescents, in English and published in PubMed, were reviewed. Results: There is less data available in the literature on FPIES in adolescents. Multiple sensitizations to food can compromise nutritional status in patients with FPIES. Several potential diagnostic biomarkers related to genomic susceptibility, altered immunologic response, mucosal inflammation and intestinal microbiota are under study/validation. The lack of age-specific diagnostic algorithms makes it difficult to understand the clinical features of persistent forms of FPIES. Conclusions: Shared transition medicine protocols tailored to adolescents could help us better understand the clinical, pathophysiological, diagnostic, and therapeutic characteristics of this delicate phase of life.
