Are painful sores that can be found in the stomach lining or small intestine. Stomach ulcers are the most visible sign of peptic ulcer disease. They occur when the thick layer of mucus that protects your stomach from digestive juices is reduced, thus enabling the digestive acids to eat away at the lining tissues of the stomach.
Symptoms:
Dull pain in the stomach
Weight loss
Not wanting to eat because of pain
Nausea or vomiting
Bloating
Burping or acid reflux
Heartburn (burning sensation in the chest)
Pain improves when you eat, drink, or take antacids
