Rome IV represents a major evolution in the understanding of functional gastrointestinal disorders, now conceptualized more broadly as disorders of gut–brain interaction. The framework integrates altered motility, visceral hypersensitivity, mucosal and immune changes, gut microbiota and central nervous system processing into a biopsychosocial model. Diagnostic criteria were refined for disorders such as irritable bowel syndrome and functional dyspepsia, with greater emphasis on bothersome symptoms and clinically useful subtyping. For internists, the practical challenge is to avoid both extremes: dismissing symptoms as “functional” without appropriate evaluation, or repeatedly investigating patients after relevant organic disease has been reasonably excluded. A structured history, alarm-feature assessment and symptom-based diagnostic framework can reduce unnecessary testing while improving therapeutic focus. Treatment can include dietary measures, behavioral interventions, neuromodulators and symptom-specific pharmacotherapy. The Rome IV model also recognizes the importance of the patient experience and doctor–patient communication. This makes the topic particularly appropriate for a conference themed around medical science and humanity, where accurate diagnosis and empathetic explanation need to work together.

Recent research defines ferro-aging as a conserved iron-lipid axis driving organ decline across primates. Age-related iron dyshomeostasis stimulates ACSL4-mediated lipid peroxidation, promoting cellular senescence. Notably, vitamin C directly inhibits ACSL4, suppressing phospholipid oxidation and multi-organ decay.
