Nail biting can have various causes, just like most other symptoms. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose nail biting, we could:
Cause | Probability | Status |
---|---|---|
Anxiety | 96% | Confirm |
Obsessive-Compulsive Disorder | 61% | Possible |
Do you bite your nails?
Possible responses:
→ No / don't know→ Sometimes a little, but my nails look quite normal → Moderately - they are bitten back to the nail bed → Severely - my nails are deformed or mostly gone |
Nail biting can be a sign of persistent anxiety.
Nail biting or picking has been linked to obsessive-compulsive disorder.
