Do you have an ulcer?

A sore or hole in the lining of the stomach is called an ulcer. How do you know that you've got one? Your doctor should evaluate your symptoms, but here's is a list of possible warning signs, courtesy of the US National Digestive Diseases Information Clearinghouse:

• Stomach pain that usually goes away after you eat, but may return several hours after.
• Pain in the stomach that feels dull, not sharp, and burning.
• Stomach pain that occurs in the middle of the night when you haven't eaten in several hours.
• Weight loss and loss of appetite.
• Nausea and vomiting.
