Complications of peptic ulcer may include bleeding, perforation, penetration, or obstruction.
Peptic ulcers sometimes bleed.
If you are vomiting blood and/or material that looks like coffee grounds, or if you have stools that are black, look like tar, or are maroon or bloody, see a doctor immediately. The chances of successfully treating your ulcer are best if you see a doctor when you first notice any bleeding.
Perforation occurs when an ulcer eats through the wall of the stomach or intestine into the abdominal (belly) cavity.
