Gastritis: Introduction

Gastritis is an inflammation of the lining of the stomach. Gastritis is a common condition. Gastritis is most frequently caused by an infection of a type of bacteria called Helicobacter pylori, which also causes peptic ulcers.

Typical symptoms of gastritis include heartburn, nausea, and vomiting. Gastritis is a treatable condition, but if can lead to dehydration and other complications, such as an increased risk of developing a peptic ulcer, if left untreated. For more details about symptoms and complications, see symptoms of gastritis.

Gastritis can also be caused by a viral infection, fungal infection, or parasite infection. Other causes of gastritis include long-term use of nonsteroidal anti-inflammatory drugs (NSAIDS), such as ibuprofen (Advil, Motrin) or naproxen (Aleve), which are irritating to the stomach lining. Another cause of gastritis is long-term physical and/or mental stress that results in the production of excessive amounts of stomach acid. Gastritis can also occur after within a few days after a stressful event, such as an illness, surgery or injury, and result in peptic ulcers that can bleed.

Smoking, alcoholism and excessive alcohol use can also cause gastritis. Drinking coffee and acidic beverages can also underlie gastritis, as can a toxic ingestion of certain poisons that are corrosive and can damage the lining of the stomach. Certain diseases, such as Crohn's disease, some autoimmune disorders, and pernicious anemia, can also cause gastritis.

Depending on the cause, gastritis can be short-term and disappear quickly, such as when gastritis occurs after a single episode of alcohol intoxication. Gastritis can also be recurring over a longer period of time, such as when gastritis is due to Crohn's disease.

Diagnosing gastritis and its root cause begins with taking a thorough personal and family medical history, including symptoms, and completing a physical examination.

Diagnostic testing generally includes an endoscopy procedure. In this procedure, a special lighted instrument is inserted through the mouth and throat into the stomach. This instrument, called an endoscope, takes pictures of the stomach and/or sends images to a computer monitor.

A biopsy may also be taken during an endoscopy. A biopsy involves taking a small sample of esophagus or stomach tissue to examine it under a microscope.

A test may also be done to test for a Helicobacter pylori infection, the most common cause of gastritis. A stool sample may be tested to determine if there is blood in the stool, which could indicate that there is a peptic ulcer or a variety of other conditions. Diagnosis may also include a complete blood count, which can help to determine if anemia or an infectious process is present.

A chemistry panel is a blood test that can evaluate if gastritis with excessive vomiting has lead to the complication of dehydration and electrolyte imbalance. An urinanalysis can also help to determine dehydration.

A diagnosis of gastritis and its cause can easily be delayed or missed because symptoms of gastritis may be intermittent and for other reasons. For information on misdiagnosis, refer to misdiagnosis of gastritis.

Some cases of gastritis can be prevented with lifestyle changes. Treatment of gastritis involves diagnosing and treating the underlying disease, disorder or condition that is causing it. For more information on treatment, refer to treatment of gastritis....more »

Article Excerpts about Gastritis

Gastritis, or dyspepsia, is an inflammation of the stomach lining. Some people have gastritis after drinking too much alcohol, eating too much, eating spicy food, or smoking. Others develop gastritis after prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs) or infection with bacteria such as Escherichia coli, Salmonella, or Helicobacter pylori. Sometimes gastritis develops after major surgery, traumatic injury, burns, or severe infections. Certain diseases, such as pernicious anemia, autoimmune disorders, and chronic bile reflux, can cause gastritis as well. (Source: excerpt from Gastritis: NIDDK)
