Gastritis

What is gastritis?

Gastritis is inflammation of the lining of the stomach. Inflammation means the stomach lining is raw and painful.

How does it occur?

Gastritis is the response of the stomach lining to injury. Many things can cause the inflammation. In its mildest form, gastritis can result from eating too much, eating too fast, or eating certain foods, such as hot spicy foods. Other common causes of gastritis are:

infection with the bacteria H. pylori
some medicines taken to treat pain and inflammation of other parts of the body, such as aspirin, ibuprofen, naproxen, and ketoprofen
steroid medicines, such as prednisone
stress from accidents or injuries, such as being in a car wreck, having a bad infection, or getting burned
emotional stress
smoking cigarettes
drinking alcohol.

Caffeine may increase the pain of gastritis.

What are the symptoms?

The symptoms of gastritis vary from person to person and they vary depending on the cause. Common symptoms are:

a sharp or burning, uncomfortable feeling in your stomach
a feeling of bloating, burping, or heartburn that moves upward into your throat
loss of appetite
nausea or vomiting
mild fever.

At its worst, gastritis can cause the lining of the stomach to bleed, which may cause you to throw up either bloody or dark brown fluid. (The dark fluid, which is partially digested blood, looks like it has coffee grounds in it.) If the blood moves through your stomach and into your intestines, you may have bowel movements that are bloody or black and tarry looking. If you have these symptoms, call your health care provider right away.

How is it diagnosed?

Gastritis is diagnosed from a careful history and physical exam, which may include a rectal exam to check for blood in the stool. Tests that may be done are:

gastric lavage, for which a tube is put into the stomach to suction fluid from the stomach for testing
upper endoscopy, which means a fiber optic scope is passed down the throat into the stomach to look at the stomach lining and possibly take a sample (biopsy) of it
blood tests to check for anemia and infections.

How is it treated?

The treatment of gastritis depends on the cause and how severe it is. Mild gastritis generally gets better on its own. Possible treatments for the symptoms of gastritis are:

taking antacids or other medicines that make stomach acid less acidic
taking medicines that reduce stomach acid
avoiding things that irritate the stomach, such as smoking, alcohol, caffeine, and spicy foods.

If infection with H. pylori is causing the gastritis, your health care provider will prescribe antibiotics.

Once the symptoms are relieved. your provider may continue to look for the underlying cause. Treatment of the cause should keep the gastritis from coming back.

How long will the effects last?

How long the effects last depends on what is causing the gastritis. For example, it may last just a few hours if it is caused by something you ate or drank. It may take several weeks to control symptoms that have been present for awhile.

How can I take care of myself?

Follow the instructions your health care provider gives you.
Eat only bland foods, such as soda crackers, toast, plain pasta, noodles, bananas, and baked or broiled potatoes and clear liquids, until symptoms stop.
Regardless of the underlying cause of the gastritis, you can make it better or worse with what you eat and drink and the medicines you take. Avoid spicy or acidic foods. When your symptoms are gone, ask your provider for diet recommendations.
Do not drink regular or decaf coffee or alcohol.
Do not take anti-inflammatory medicine (such as aspirin and ibuprofen). If you need something for pain, acetaminophen (Tylenol) is safe if your liver is normal and you take it as directed.
Long-term gastritis increases the risk of stomach cancer. Be sure to let your provider know if your symptoms are not getting better and especially if they are getting worse.

How can I help prevent gastritis?

Everyone's stomach is different. Some ways that might help prevent gastritis are:

If you find that aspirin causes you to get gastritis, then use a different medicine. (If your health care provider has prescribed aspirin for you, be sure to ask about stopping the aspirin.)
Keep track of what you ate before an attack. Avoid foods that seem to trigger gastritis. If you get gastritis every time you eat chili, avoid it.
