萎缩性胃炎是胃变小了？它一定会癌变吗？6类人建议筛查

Core Viewpoint - The news highlights the severe health risks associated with atrophic gastritis, particularly its potential to progress to gastric cancer, as illustrated by the tragic case of a 27-year-old woman who suffered from the condition and ultimately passed away due to complications [1][7]. Summary by Sections Definition and Nature of Atrophic Gastritis - Atrophic gastritis is a type of chronic gastritis characterized by the loss of gastric mucosal glands, leading to a thinner mucosal layer and reduced digestive function, which can progress to severe conditions including gastric cancer [2][7]. - The condition is often asymptomatic, with symptoms like abdominal discomfort and poor appetite being non-specific and closely related to the patient's psychological state [2][3]. Prevalence and Risk Factors - The prevalence of atrophic gastritis in the population exceeds 20%, with a higher incidence in individuals over 60 years old, who account for approximately 16.47% of cases [3]. - Key risk factors include age, Helicobacter pylori infection (approximately 40.66% infection rate in the population), and poor lifestyle habits such as irregular eating patterns and excessive alcohol consumption [3][5]. Screening Recommendations - Six groups are recommended for priority screening for atrophic gastritis: individuals aged 40 and above with gastrointestinal symptoms, those with H. pylori infection, individuals with a family history of gastric cancer, people with poor lifestyle habits, patients with autoimmune diseases, and those on long-term NSAIDs [5][6]. Diagnostic Methods - Endoscopy is the primary method for assessing gastric mucosal atrophy, with histopathological examination being essential for diagnosis [6]. Cancer Risk and Prevention - Atrophic gastritis is considered a precancerous condition, with varying cancer risk rates based on endoscopic findings. Regular screening and monitoring are crucial for early detection and intervention [7][9]. - Preventive measures include dietary management, eradication of H. pylori, and maintaining a positive mental attitude to support gastrointestinal health [8][9].
