NCT ID NCT07388459
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 600 adults with autoimmune atrophic gastritis, a condition where the immune system attacks the stomach lining, leading to nutrient deficiencies and increased cancer risk. Researchers aim to track how the disease progresses over time and identify factors that lead to complications. The goal is to improve early diagnosis and prevent serious outcomes.
