Duodenitis is inflammation of the first part of the small bowel, called the duodenum.
Symptoms may include upper abdominal pain or burning, bloating, nausea, vomiting, indigestion, and sometimes pain that feels like ulcer symptoms.
Imaging helps when doctors need to look for wall thickening, nearby inflammation, or complications, especially if the pain is persistent or there is concern about obstruction or another abdominal problem.
CT or contrast studies may show wall thickening or nearby inflammation, though endoscopy often provides direct evaluation.
Treatment depends on the cause and may include acid suppression, infection treatment, dietary measures, and follow-up care.
