Duodenum

Medical Specialties: Family practice, Gastroenterology


Clinical Definition

The duodenum is the first part of the small intestine, located between the stomach and the jejunum. 


In Our Own Words

The duodenum is the part of the small intestine where food mixes with stomach acids and other digestive juices (bile) from the pancreas and stomach. Your body absorbs vitamins, minerals and macro-nutrients (such as folate, iron and calcium) in this first segment of the small intestine. Excessive stress, smoking and alcohol abuse are prime precursors of duodenal ulcers, so initiating a healthier lifestyle can help prevent disorders of the duodenum.
