Symptoms of gastritis include a gnawing feeling in the abdomen at night, vomiting blood, stomach pain, lack of appetite and indigestion. Bloating, nausea, hiccups and black, tarry stools are also a sign of gastritis, according to WebMD.
Gastritis is the irritation, swelling or erosion of a person's stomach lining. It is either acute or chronic. Causes of gastritis include excessive alcohol consumption, excessive vomiting and stress. Medication such as anti-inflammatory drugs also causes gastritis. Other causes of gastritis include Helicobacter pylori, pernicious anemia, bile reflux, bacterial infection and viral infection. Untreated gastritis causes severe blood loss and increases the risk of stomach cancer development. Diagnostic tests that ascertain gastritis include upper endoscopy, blood tests and stool tests, states WebMD.
Treatment options for gastritis include taking antacids and proton pump inhibitors, which reduce stomach acid. A person with gastritis should avoid spicy foods. Vitamin B-12 shots treat gastritis that results from pernicious anemia. Avoiding irritating foods containing lactose and gluten helps in gastritis treatment, notes WebMD.
Gastritis risk factors include using common pain relievers such as ibuprofen, naproxen and aspirin regularly, old age, and autoimmune gastritis, which occurs when the body attacks the cells on the stomach lining. People with HIV/AIDS are also at a high risk of developing gastritis, according to Mayo Clinic.
