Gastric metaplasia is a condition in which the cells lining the stomach undergo a transformation into a different type of cell, typically resembling those found in the intestine. This process can occur as a response to chronic inflammation or injury to the stomach lining, and is considered a pre-cancerous condition as it can increase the risk of developing gastric cancer. Research in this area focuses on understanding the underlying mechanisms driving this transformation, identifying risk factors and biomarkers for gastric metaplasia, and developing strategies for early detection and prevention of gastric cancer. Studies may also explore potential therapeutic interventions to reverse or halt the progression of gastric metaplasia.
