There is no clear evidence to suggest that the stress of modern life or a steady diet of fast food causes ulcers in the stomach and small intestine.The stomach produces a strong acid to help digest food and protect against microbes. To protect the body's tissues from this acid, it also secretes a thick layer of mucus.
If the mucus layer is worn away and stops functioning effectively, the acid can damage the stomach tissue, causing an ulcer.
