Stomach ulcers, also referred to as gastric ulcers, are painful sores in the stomach lining. Stomach ulcers are a kind of peptic ulcer disease. Peptic ulcers are any ulcers that affect both the stomach and small intestines.
Stomach ulcers happen when the thick layer of mucus that helps protect your stomach from digestive juices is lowered. This allows the digestive acids to eat away at the tissues that line the stomach, causing an ulcer.
Furthermore, stomach ulcers may be cured easily; however, they can become severe without proper treatment.
