Duodenitis
Duodenitis (pronounced doo-oh-deh-NIGH-tis) is a medical condition characterized by inflammation of the duodenum, the first part of the small intestine.
Etymology
The term "Duodenitis" is derived from the Latin word "duodenum" (meaning twelve, as the duodenum is about twelve finger-breadths long) and the Greek suffix "-itis" (meaning inflammation).
Definition
Duodenitis is a condition that involves inflammation of the inner lining of the duodenum. This inflammation can lead to a variety of symptoms, including abdominal pain, nausea, vomiting, and in severe cases, bleeding.
Causes
The most common cause of duodenitis is infection with the bacterium Helicobacter pylori. Other causes can include regular use of nonsteroidal anti-inflammatory drugs (NSAIDs), excessive alcohol consumption, and certain autoimmune disorders.
Symptoms
Symptoms of duodenitis can vary depending on the severity of the inflammation. Common symptoms include upper abdominal pain, nausea, vomiting, and a feeling of fullness. In severe cases, duodenitis can cause bleeding in the duodenum, which can lead to bloody or tarry stools, or vomiting blood.
Diagnosis
Diagnosis of duodenitis typically involves an endoscopy, a procedure in which a thin tube with a camera is inserted through the mouth and into the duodenum. This allows the doctor to visually inspect the duodenum and, if necessary, take a biopsy for further examination.
Treatment
Treatment for duodenitis usually involves addressing the underlying cause of the inflammation. This can include antibiotics to treat a Helicobacter pylori infection, or changes in medication if NSAIDs are the cause. In some cases, medications to reduce stomach acid may also be prescribed.
