Gastroscopy showing atrophic gastritis C1 may be followed by histopathologic examination to help clarify the specific condition. Gastroscopy showing atrophic gastritis C1 indicates that atrophic gastritis involves the gastric sinus area, and the patient can undergo further pathologic examination in order to help clarify the specific condition. If the examination reveals heterogeneous hyperplasia or atypical hyperplasia, it suggests precancerous lesions or early gastric cancer, etc., which need to be taken seriously. If there is no atypical hyperplasia, the condition is not serious, but active treatment and regular review are still needed. It is worth noting that pathological examination is currently the “gold standard” for clinical diagnosis of atrophic gastritis, therefore, it is recommended that patients with atrophic gastritis C1 detected by gastroscopy should undergo further pathological examination to clarify the specific condition and facilitate the guidance of diagnosis and treatment.
