Alcohol can make your duodenitis worse. Talk to your provider if you need help to stop drinking.

Babies often put items in their mouths to explore them. Button batteries are easy to swallow and can cause serious damage. Keep the battery covers of electronic devices such as remote controls taped closed. Store all batteries and toxic materials where children cannot get to them. Use childproof locks to keep children away from dangerous materials.

  • Do not eat foods that cause irritation. Foods such as oranges and salsa can cause burning or pain. Eat a variety of healthy foods. Examples include fruits (not citrus), vegetables, low-fat dairy products, beans, whole-grain breads, and lean meats and fish. Try to eat small meals, and drink water with your meals.
