Gastritis is inflammation of the stomach lining. Duodenitis is inflammation of the duodenum (the first part of the small intestine), which is located just below your stomach. Both gastritis and duodenitis have the same causes and treatments.
Both conditions may occur in men and women of all ages. The conditions may be acute or chronic. The acute forms come on suddenly and last for a short time. The chronic forms may progress slowly and last for months or years. The conditions are curable and generally don’t cause any long-term complications.
The most common cause of gastritis and duodenitis is a bacterium called Helicobacter pylori (H. pylori). Large amounts of the bacteria invading your stomach or small intestine can cause inflammation.
H. pylori can be transferred from person to person. It can also be transmitted through contaminated food and water, although this is uncommon in the United States. According to the National Digestive Diseases Information Clearinghouse, approximately 20 to 50 percent of people in the United States may be infected with H. pylori. In comparison, up to 80 percent of people in developing countries are infected with the bacteria.
Other common causes of gastritis and duodenitis include the long-term use of certain medications, such as aspirin, ibuprofen, or naproxen, or drinking too much alcohol.
Less common causes include:
Inflammatory bowel disease (IBD) is the chronic inflammation of part or all of the digestive tract. The exact cause is unknown, but doctors believe that IBD may be the result of an immune disorder. It’s also possible that the disease is inherited. Examples of IBD include ulcerative colitis (inflammation of the colon and rectum) and Crohn’s disease. Crohn’s disease may affect any part of the digestive tract and often spreads beyond the intestinal lining and into other tissues.
A study published in Inflammatory Bowel Diseases reported that people with inflammatory bowel disease are much more likely to develop a form of gastritis or duodenitis that isn’t caused by H. pylori than people who don’t have the disease.
Gastritis and duodenitis don’t always produce signs or symptoms. When they do, common symptoms include:
In some cases, feces may appear black in color and vomit may look like used coffee grounds. These symptoms can indicate internal bleeding. Call your doctor right away if you experience either of these symptoms.
There are several tests your doctor can use to diagnose gastritis and duodenitis. H. pylori can be detected through blood, stool, or breath tests. For a breath test, you will be instructed to drink a clear, tasteless liquid and then breathe into a bag. This will help your doctor detect any extra carbon dioxide gas in your breath if you are infected with H. pylori.
Your doctor may also perform an upper endoscopy with biopsy. During this procedure, a small camera attached to a long, thin, flexible tube (an endoscope) is moved down the throat to look into the stomach or small intestine. This test will allow your doctor check for inflammation. Your doctor may take a few small tissue samples for further testing if any inflammation can’t be detected visually.
Depending on the cause of your condition, your symptoms may go away without treatment. The type of care you receive will depend on the cause and severity of your gastritis or duodenitis. Fastritis and duodenitis usually clear up without complications.
H. pylori infections are treated with antibiotics. Your doctor may recommend a combination of drugs to kill the infection, and most people will need to take antibiotics for two weeks or longer.
Over-the-counter acid blockers (drugs that work to reduce the amount of acid released into your digestive tract) may be recommended. These include:
Proton pump inhibitors (drugs that block cells that produce acid) are also used to treat these conditions. These include:
Your doctor may prescribe prescription-strength acid reducers to keep stomach acid from irritating the lining of your digestive tract.
Your doctor may suggest antacids to neutralize stomach acid and relieve pain. These are over-the-counter and don’t need to be prescribed. Antacid options include:
calcium carbonate and magnesium hydroxide (Rolaids)
Antacids can prevent your body from absorbing other medications, so it is recommended that you take antacids at least an hour before other medications to avoid this side effect.
Avoid smoking, alcohol, spicy foods, acidic beverages (such as orange juice or pineapple juice), and medications (such as aspirin) that are hard on the stomach. All of these can make your symptoms worse.
Make an appointment with your doctor if your symptoms don’t go away with treatment. Call your doctor immediately if:
Untreated cases of gastritis and duodenitis can become chronic. This can lead to stomach ulcers and stomach bleeding. In rare cases, extensive thinning of the stomach lining can change the cells over time and increase your risk of developing stomach cancer.
Talk to your doctor if your gastritis or duodenitis isn’t clearing up so you can determine the cause and make sure you get the treatment you need.
