A stomach ulcer is a wound that forms on the inside of the stomach. Often it’s a side effect of some medications, especially when human painkillers are given to cats. Some cases can be severe and even life-threatening.

The acid inside the stomach is fundamental for digestion and protection from infections. However, the stomach needs to protect itself from the acid with special secretions and other mechanisms. If something damages these defences, the acid will cause one or more wounds that will struggle to heal. Stomach ulcers seem to be uncommon in cats, but could potentially cause serious complications like internal bleeding or peritonitis.
