Gastritis can be caused by irritation due to excessive alcohol use, chronic vomiting, stress, or the use of certain medications such as aspirin or other anti-inflammatory drugs. If gastritis is left untreated, it can lead to a severe loss in blood and may increase the risk of developing stomach cancer.
Symptoms of gastritis vary among individuals, and in many people there are no symptoms. However, the most common symptoms include:
Nausea or recurrent upset stomach
Burning or gnawing feeling in the stomach between meals or at night
Loss of appetite
Vomiting blood or coffee ground-like material
Black, tarry stools
Taking antacids and other drugs to reduce stomach acid, which causes further irritation to inflamed areas.
Avoiding hot and spicy foods.
For gastritis caused by H. pylori infection, your doctor will prescribe a regimen of several antibiotics plus an acid blocking drug (used for heartburn).
If the gastritis is caused by pernicious anemia, B12 vitamin shots will be given. Eliminating irritating foods from your diet such as lactose from dairy or gluten from wheat.
