Nail biting, also known as onychophagy or onychophagia, is a common oral compulsive habit. It is often associated with feelings of boredom, loneliness, or nervousness, and can sometimes be a symptom of a more serious psychological or emotional problem. Nail biting can also have negative health consequences, such as the transfer of bacteria from the nails to the mouth, and may lead to feelings of guilt and shame.

Nail biting is a compulsive habit, sometimes described as a parafunctional activity
Nail biting can be a source of guilt and shame for the nail biter, leading to a reduced quality of life and increased stigmatisation. It can also transfer pinworms or bacteria from the nails to the mouth, and if the bitten-off nails are swallowed, this can cause stomach problems.
Nail biting is often associated with feelings of nervousness, boredom, loneliness or hunger. It can also be a habit transferred from earlier thumb or finger sucking. While it can occur without symptoms of another psychiatric condition, it has been linked to attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder, separation anxiety, enuresis, tic disorder, and other mental health issues. It may also be linked to a tendency towards perfectionism or a desire for stimulation.
Like other body-focused repetitive behaviours, nail biting appears to run in families and may share neurological roots with OCD, anxiety, and other mental health disorders. If you have repeatedly tried to quit nail biting and the problem persists, it is recommended that you consult a doctor.

Nail biting, also known as onychophagy or onychophagia, is an oral compulsive habit. It is very common, especially among children, of which 25-35% bite their nails. Nail biting is sometimes described as a parafunctional activity, which is the use of the mouth for an activity other than speaking, eating or drinking. It can also be a habit transferred from thumb or finger sucking.
Nail biting can be a source of guilt and shame, reducing quality of life and increasing stigmatisation. It can also transfer pinworms or bacteria from the anus region to the mouth. If the bitten-off nails are swallowed, this can cause stomach problems.

Nail biting, also known as onychophagy or onychophagia, is an oral compulsive habit. It is very common, especially among children, of which 25-35% bite their nails. Nail biting can occur without symptoms of another psychiatric condition, but it can be associated with attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder, separation anxiety, enuresis, tic disorder, and other mental health issues. It can also be a habit transferred from earlier thumb or finger sucking.
Nail biting can also transfer pinworms or bacteria buried under the surface of the nail from the anus region to the mouth. If the bitten-off nails are swallowed, stomach problems can occasionally develop. Nail biting can be a source of guilt and shame for the nail biter, a reduced quality of life, and increased stigmatisation in the inner family circles or at a more societal level.
Other body-focused repetitive behaviours include onychotillomania (nail picking), excoriation disorder (skin picking), dermatophagia (skin biting), and trichotillomania (the urge to pull out hair), and all of them tend to coexist with nail biting. As an oral parafunctional activity, it is also associated with bruxism (tooth clenching and grinding), and other habits such as pen chewing and cheek biting.
Some researchers also speculate that nail biting may partially stem from an overall tendency towards perfectionism in one's personality, or from a desire to seek stimulation when bored or frustrated. For some people, nail biting may be a sign of a more serious psychological or emotional problem. If you've repeatedly tried to quit and the problem persists, consult a doctor.
