What is duodenitis?

Duodenitis: Overview

The duodenum (say "doo-AW-duh-num") is the first part of the small intestine. It connects to the stomach. It's about 10 inches long and curved, almost forming a circle.

Duodenitis (say "doo-aw-duh-NY-tus") may feel like an upset stomach. It happens when something irritates the lining of the duodenum. Many things can cause it. These include an infection 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.

How can you care for duodenitis?

  • If your doctor prescribed antibiotics, take them as directed. Do not stop taking them just because you feel better. You need to take the full course of antibiotics.
  • Be safe with medicines. If your doctor prescribed medicine to decrease stomach acid, take it as directed. Call your doctor if you think you are having a problem with your medicine.
  • Do not take any other medicine, including over-the-counter pain relievers, without talking to your doctor first.
  • If your doctor recommends over-the-counter medicine to reduce stomach acid, such as Pepcid AC (famotidine) or Prilosec (omeprazole), follow the directions on the label.
  • To prevent dehydration, drink plenty of fluids. Choose water and other clear liquids until you feel better. If you have kidney, heart, or liver disease and have to limit fluids, talk with your doctor before you increase the amount of fluids you drink.
  • Limit how much alcohol you drink.
  • Avoid coffee, tea, cola drinks, chocolate, and other foods with caffeine. They increase stomach acid.
