Erythematous mucosa of the stomach is the stomach’s red, inflamed lining. This usually happens when a person has been diagnosed with gastritis and an endoscopy shows that the lining of the stomach is inflamed. During an endoscopy, biopsies may or may not be taken to find the cause of the erythema.
Gastritis of the stomach can be caused by things like alcohol, bile reflux, nonsteroidal anti-inflammatory drugs, and bacterial infections like Helicobacter pylori. Some diseases, like sarcoidosis and even allergies, can cause erythematous changes in the stomach. The redness of the stomach lining could also be caused by radiation treatments.
If a person has gastritis, they may or may not have symptoms. Some symptoms, like mild stomach pain after eating or heartburn, may not be too bad, but others are more serious. Gastritis can cause weight loss, vomiting, and bloody stools.
Most of the time, acute gastritis is a short-term inflammatory process. Chronic gastritis, on the other hand, can cause the gastric mucosa to change over time, which can lead to muscle atrophy and even cellular changes that can cause stomach cancer.
People think that stomach cancer develops in stages, starting with an H. pylori infection, then chronic gastritis, atrophy, metaplasia, and finally dysplasia, or the growth of cancer cells.
