Most ulcers are caused by a bacterial infection, but acid in the stomach contributes to it, making ulcers more painful. The following tips may help an ulcer heal:
  • Don't smoke.

  • Avoid taking anti-inflammatory medications, such as ibuprofen or aspirin.

  • Avoid caffeinated foods and beverages, and alcohol.

  • Avoid foods or drinks that cause you pain, discomfort or heartburn.
