Symptoms of gastric mucosal abnormality include loss of appetite, nausea, vomiting and dyspepsia, a condition where a person suffers bloating, indigestion and abdominal pain, reports the MUSC Digestive Disease Center. These are symptoms of gastritis. In severe cases, the stomach bleeds and the individual vomits blood.
Gastritis is often caused by the gastric mucosa failing to produce the right amounts of gastric juices, the MUSC Digestive Disease Center reports. Sometimes an endoscopic exam reveals the stomach's mucosal layer to be inflamed and swollen. The exam may even show bleeding areas in the stomach.
Gastritis is either chronic or acute, explains the MUSC Digestive Disease Center. Chronic gastritis has a gradual onset, may be asymptomatic in its early stages and can last for years. Acute gastritis sometimes has a sudden onset but usually resolves after a short time. It is often the result of over-use of medications such as aspirin or ibuprofen or heavy alcohol consumption. These substances wear away the gastric mucosa.
A bacteria called Helicobacter pylori is sometimes the culprit behind chronic gastritis, the MUSC Digestive Disease Center advises. Though most people harbor this bacteria in their stomachs, infection can damage the gastric mucosa. In some cases, a person's own immune system attacks the stomach cells that produce acid. This disorder often has no symptoms.
