How are ulcers caused?

Where?: Stomach is usually excessive acid or sometimes a bacterial or lack of problem. Mouth ulcers usually are from trauma or herpetic virus.

Acid: "peptic" ulcers, most commonly referred to as gastric or stomach ulcers are mostly a result of an imbalance of acid to normal acid protection. The stomach is a very hearty organ. It withstands the harsh acid environment that it creates. But certain bacteria, or medications such as Aspirin can affect the normal stomach protection mechanisms and allow for wounds (ulcers) to occur in the stomach.
