Duodenitis may come in different forms, but this inflammatory disease almost always involves the irritation of the mucous lining of the duodenum.

What is Duodenitis?

In medical terms, duodenitis is an indication of inflammation of the duodenum. The duodenum is a part of the small intestine and is connected to the stomach, and when this region is inflamed it can cause stomach pain and gastritis. Duodenitis can further lead to duodenal ulcers that develop in the small intestine, thus causing more pain.

There are three types of duodenitis namely:

  • Chronic and acute
  • Non-erosive and erosive
  • Post-bulbar and bulbar



Duodenitis may be caused by a variety of means but the most common ones are:

  • Helicobacter pylori infection: This bacterium found in the stomach is known to lead to the development of duodenitis.
  • Excessive secretion of stomach acid
  • Non-steroidal anti-inflammatory drugs (NSAID): Aspirin and anti-inflammatory drugs should be discontinued or even completely avoided. It is also possible that if the inflammation is severe enough, it can cause intestinal obstruction.
  • Smoking: This may cause and certainly exacerbates the development of duodenitis.
  • Ill or hospitalized patients: Those with poor nutritional intake are susceptible to this disease.


The symptoms of duodenitis include the following:

  • Abdominal pain and discomfort
  • Burning sensation in the stomach
  • Damage to the intestines and liver
  • Pain around the navel
  • Vomiting
  • Nausea
