The duodenum (say "doo-AW-duh-num") is the first part of the small intestine. It connects to the stomach. It's about 25 cm long and curved, almost forming a circle.
Duodenitis (say "doo-aw-duh-NY-tus") may feel like a sore and upset stomach. It happens when something irritates the lining of the duodenum. Many things can cause it. These include an infection such as the flu or something you ate or drank. Certain medicines or having a sore (ulcer) on the lining of the duodenum also can cause it. Your belly may bloat and ache. You may belch, vomit, and feel sick to your stomach.
You should be able to relieve the problem by taking medicine. And it may help to change your diet. If the problem lasts, your doctor may prescribe different medicine.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
