Gastric sinus erosion is caused by inflammation of the gastric mucosa.
Firstly, acute gastric mucosal damage leading to erosion is more likely; secondly, H. pylori can tolerate the acidic environment of the stomach and excite toxins to destroy the gastric mucosa, causing chronic gastritis and leading to sinus erosion; furthermore, some drugs such as aspirin, Anacin, painkiller and other non-steroidal anti-inflammatory drugs or hormones damage the gastric mucosa and also cause erosion; finally, such as huge trauma, mental stimulation and other stress reactions caused by the body that indirectly leads to gastric sinus erosion.
