Resumen
Autoimmune atrophic gastritis can lead to serious conditions, including malabsorption and vitamin deficiencies, that may cause anemia, neurological disorders, and gastric malignancies. This paper provides recent evidence on the pathogenesis, diagnosis, clinical presentation, risk of malignancies, endoscopic surveillance, and treatment of autoimmune atrophic gastritis. This review provides a valuable update for healthcare professionals and researchers, and the findings may help improve the diagnosis and management of patients with autoimmune atrophic gastritis, leading to improved outcomes and shaping future research directions.
