Symptoms of stomach ulcers can be varied, and attributed to other things, making them difficult to identify without medical help. Some ulcers also produce no symptoms at all, or only after they have perforated the stomach wall and become a serious medical problem. Lightheadedness, vomiting blood, or having black or tarry stools – all signs of internal bleeding, potentially due to an ulcer – should be treated immediately by a medical professional.
