Gastritis
Gastritis is an inflammation of the lining of the stomach.
The most common symptom is upper abdominal pain, but it may occur anywhere from the upper left portion of the abdomen around to the back.
The pain may be dull, burning, aching, sore, or sharp. Other possible symptoms include nausea and vomiting, bloating, loss of appetite and heartburn. Complications may include bleeding, stomach ulcers, and stomach tumors.
Common causes include infection with Helicobacter pylori and use of nonsteroidal anti-inflammatory drugs (NSAIDs). Less common causes include alcohol, smoking, cocaine, autoimmune problems, and Crohn’s disease. Endoscopy, blood tests, and stool tests may help with diagnosis.
Treatment may include medications such as antacids, H2 blockers, or proton pump inhibitors. If H. pylori is present it may be treated with a combination of antibiotics such as amoxicillin and clarithromycin.
Other signs and symptoms may include the following:
- Nausea
- Vomiting
- Belching
- Bloating
- Loss of appetite
- Weight loss
