Peptic ulcers are sores on the lining of your stomach, upper small intestine or esophagus. About 10 percent of all Americans will have an ulcer at some point in their lives, according to MayoClinic.com. Although doctors formerly believed that stress and poor diet caused ulcers, research has shown that helicobacter pylori bacteria are responsible for most cases. The use of nonsteroidal anti-inflammatory drugs, such as ibuprofen, may also play a role. Ulcers are treatable with medications, but complications of untreated ulcers -- such as perforations, hemorrhage and infection -- may be life threatening.
Abdominal Pain
Abdominal pain is a primary symptom of ulcers. Pain may be either in one specific spot or over a large area. You may feel a burning pain from your navel up to your breastbone that can last several minutes to several hours, or the pain may take the form of a gnawing or aching sensation. Discomfort is usually worse when your stomach is empty, and it may intensify during the night. The New York Times Health Guide notes that a gnawing sensation that is relieved by eating points to a duodenal ulcer, located in your small intestine. A dull ache that is not relieved by eating is indicative of a gastric, or stomach, ulcer. According to the National Digestive Diseases Information Clearinghouse, it is possible to have gastric and duodenal ulcers at the same time.
Burning Throat, Nausea and Fullness
You may feel a burning sensation in your throat, accompanied by a bitter or sour taste. Acid reflux, or digestive acids backing up into your esophagus, is the cause for such symptoms. This acid reflux also may be accompanied by belching, nausea and a feeling of fullness.
Emergency Signs and Symptoms
An ulcer may extend all the way through the lining of the stomach, small intestine or esophagus, causing a perforation; this is a medical emergency. Immediate medical care should be sought if you experience tarry, black or bloody stools or if you experience severe vomiting -- especially if the vomit contains blood or a dark, grainy substance resembling coffee grounds; this is a sign of hemorrhage, notes MedlinePlus. Also seek emergency care if you have severe abdominal pain, with or without vomiting or the appearance of blood. Other emergency signs include a rigid or hard abdomen that is tender to the touch, fainting, excessive sweating and confusion.
