In this case report, an 80-year-old male patient presented with exertional fatigue and was diagnosed with severe anemia. Gastroscopy revealed gastric antral vascular ectasia (GAVE) and autoimmune gastritis, suggesting that GAVE is triggered by autoimmune gastritis, possibly related to hypergastrinemia. This rare case may contribute to our understanding of the unknown cause of GAVE.
An 80-year-old man presented to our hospital with general fatigue on exertion that had gradually worsened over 6 months. His blood test revealed severe anemia, and gastroscopy revealed findings consistent with gas-tric antral vascular ectasia (GAVE) and autoimmune gastritis. We diagnosed the patient with severe anemia caused by GAVE and autoimmune gastritis. The present case suggested that GAVE is triggered by autoim-mune gastritis, and the mechanism is likely related to hypergastrinemia. The reporting of this rare case may help elucidate the cause of GAVE, which is currently unknown.
