Left untreated, peptic ulcers can result in:

  • Internal bleeding. Bleeding can occur as slow blood loss that leads to anemia or as severe blood loss that may require hospitalization or a blood transfusion. Severe blood loss may cause black or bloody vomit or black or bloody stools.
  • Infection. Peptic ulcers can eat a hole through the wall of your stomach or small intestine, putting you at risk of serious infection of your abdominal cavity (peritonitis).
  • Scar tissue. Peptic ulcers can also produce scar tissue that can block passage of food through the digestive tract, causing you to become full easily, to vomit and to lose weight.
