👉 Duodenal stenosis is a condition in which the duodenum (the small intestine) becomes narrowed or blocked. This can occur due to various factors, such as inflammation, infection, or damage from certain conditions like diverticulitis and appendicitis. Duodenal stenosis often leads to abdominal pain, nausea, vomiting, and difficulty digesting food. Treatment for duodenal stenosis typically involves medications and lifestyle changes to improve the condition and prevent further complications.
