Canker Sores

Do you experience Canker Sores… you could be lacking in B12

They may look pale or yellow like an ulcer with a red outer ring, they are not contagious. You may experience one, or more at a time, and for reason unexplained women seem to get them more than men.

The cause of canker sores is not clear.

It may be due to:

  • Diet

  • Weakened immune system (for example, from the cold or flu)

  • Hormone changes

  • Stress

  • Lack of certain vitamins and minerals in the diet, including vitamin B12 or folate

  • Less commonly, mouth sores can be a sign of an illness, tumor, or reaction to a medication.

  • This can include:

  • Autoimmune disorders

  • Cancer of the mouth

  • Infections such as hand foot mouth disease

  • Weakened immune system — for example, if you have AIDS or are taking medication after a transplant

  • Drugs that may cause mouth sores include aspirin, beta-blockers, chemotherapy medicines, penicillin, sulfa drugs, and phenytoin.
