Signs and Symptoms of Ulcers

Vomiting blood. As a stomach ulcer grows more serious, and especially if it is left untreated, it can escalate into a perforated ulcer. This is when a peptic ulcer has become serious to the point where there is an actual hole in the lining of the stomach, as well as in the stomach wall. This leads to food and other matter, including stomach acid, entering the abdominal cavity itself. This is an extremely serious health issue and requires urgent treatment. Vomiting blood is a common symptom of this.
