How do other illnesses affect aphthous stomatitis (canker sore)?

Other illnesses can lead to mouth sores. Sore can occurs in people with weak immune systems -- the very young, elderly or those debilitated by disease, such as diabetes or leukemia. Bacteria or viruses may also cause the sores, as well as another condition. Mouth sores can also be common for people with oral cancer.
Other illnesses may affect aphthous stomatitis (canker sores). Your immune system is involved in canker sores, so an immune disorder such as HIV or AIDS can bring these sores on. Digestive problems such as celiac disease may also make you more likely to get canker sores. Allergies also can play a role, so if you have canker sores that keep coming back, you may want to work with your doctor to see if you are allergic to any foods. Emotional stress, while not an illness, is also linked with canker sores. If you've been under a lot of stress lately, taking steps such as getting exercise and trying relaxation techniques to lower your stress may help prevent canker sores. In women, hormonal changes through the menstrual cycle can also trigger an outbreak of canker sores. Many women, for example, find that canker sores get better or go away during pregnancy.

When aphthous stomatitis (canker sores) does not clear up within two weeks or ulcers are larger or more painful than normal, it may be the affect of other illnesses or an underlying health condition. People with autoimmune diseases such as AIDS may have large ulcers that last much longer than normal. A person who is under a great deal of stress is also a likely candidate for canker sores. Having a digestive disease such as Crohn's disease or celiac disease predisposes a person to outbreaks of these mouth ulcers.
