Core Tip

Core Tip: The management of dyspepsia in patients with autoimmune gastritis (AIG), a chronic, immune-mediated disease, remains a challenge, as it can overlap with functional dyspepsia and gastroesophageal reflux disease. Currently, there are no specific therapies. A tailored treatment approach based on a better understanding of putative pathogenic mechanisms underlying symptoms is needed. Prokinetic agents, antidepressant drugs, and non-pharmacological treatments may be helpful, although not adequately evidence-based supported. As a future perspective, targeting dyspepsia in AIG based on changes in the microbiota and advanced endoscopic techniques to treat severe dyspeptic symptoms might be an area of ongoing research.
