Possible causes
Viral mucositis
- Candidiasis (oral, hands and feet)
Normal human skin contains bacteria and fungi. Candidiasis occurs when the fungus overgrows and invades the skin. Risk factors include warm moist environments and a weakened immune system.
- Stomatitis
Inflammation of the mouth surface causes ulcers. Various factors can cause this, such as vitamin deficiencies, medications, and autoimmunity (the body's immune system attacking itself). Often, no clear cause is found, and the ulcers heal on their own.
