What is Chronic gastritis (CG) ?</h3>
Chronic gastritis (CG) is one of the most common and insidious diseases in humans, affecting hundreds of millions of people worldwide to varying degrees and extents. According to endoscopic diagnosis, the prevalence of CG in China is close to 90%.
Because CG does not always cause signs and symptoms, historical studies have failed to show a significant link between CG and gastrointestinal symptoms. However, in clinical practice, many CG patients complain primarily of gastrointestinal discomforts such as stomachache, bloating, nausea, vomiting, and loss of appetite.
In fact, in a national multicenter survey of 8892 CG patients in China, 86.8% of patients reported gastrointestinal symptoms, and approximately 40% of CG patients reported more than one such symptom.
