Living with Oral submucous fibrosis
A long-lasting mouth condition in which the lining stiffens, making it hard to open the mouth, often linked to chewing areca nut.
Understanding Oral submucous fibrosis
It is common in India and Southeast Asia but rare elsewhere. It causes burning and pain in the mouth, loss of taste, pale fibrous bands, and stiffening of the mouth and throat. Mouth opening gets progressively smaller (trismus). There is an increased risk of oral squamous cell cancer, reported at 3 to 19%. GARD lists onset as any time in life.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Burning and pain in the mouth
- Loss of taste
- Pale fibrous bands in the mouth lining
- Trouble opening the mouth (trismus)
- Narrow mouth opening
- Inflamed lips
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
