Management of autoimmune gastritis

Treatment of autoimmune gastritis aims to restore and maintain iron and vitamin B₁₂ concentrations, if they are low. If oral iron supplements are not effective, intravenous iron infusions may be needed (see Iron deficiency). If the vitamin B₁₂ concentration is low, supplementation with intramuscular vitamin B₁₂ injection is usually required (see Vitamin B₁₂ supplementation).

Although the value and cost effectiveness of endoscopic surveillance for gastric mucosal dysplasia and cancer have not been confirmed, endoscopy is commonly recommended every 3 to 4 years for patients with autoimmune gastritis.
