Geographic tongue Causes and Risks:
The specific cause of geographic tongue is unknown, although allergies may be involved. Other causes may include local irritation of a small portion of the tongue from hot or spicy foods, alcohol, tobacco, or other local irritants. The pattern on the surface of the tongue may change very rapidly. The pattern results from the loss of tongue papillae (tiny finger-like projections on the surface of the tongue), giving areas of the tongue flat spots, and the subsequent geographic appearance. These areas of papillae loss are called denuded. Denuded areas may persist for more than a month. Occasionally, mild irritation of the tongue is reported.
Prevention:
Avoid local irritation (hot/spicy food, alcohol, tobacco, and so on) if you are prone to geographic tongue.
Symptoms:
- map-like appearance to the surface of the tongue
- patches and lesions on the tongue
- beefy red
- smooth
- sore and burning pain (in some cases)
- location changing from day to day
Signs and Tests:
Examination of the tongue is usually sufficient to make the diagnosis. No tests are usually necessary.
Treatment:
There is no treatment.
Prognosis:
Geographic tongue is a benign condition, but it can be persistent.
Complications:
Call Your Healthcare Provider:
Call for an appointment with your health care provider if symptoms of geographic tongue persist for longer than 10 days.
Call your health care provider if tongue swelling is severe and breathing, speaking, chewing, or swallowing difficulties are present. Blockage of the airway is an emergency situation that needs immediate attention.
Geographic tongue is a descriptive term for the map-like appearance of some people's tongues. The borders may change fairly rapidly. The condition is harmless. The cause is not known. It is thought that this condition may be related to vitamin deficiency, stress, or heredity.
