Nail biting, clinically known as onychophagia, is a common behaviour among children and young adults. While it may be a fleeting childhood habit, it can sometimes be a symptom of Obsessive-Compulsive Disorder (OCD). Onychophagia can cause severe damage to the nails and cuticles, and lead to bacterial infections and dental problems. It is often regarded as a tension-reducing measure and can be challenging to break. OCD involves obsessions and compulsions, where compulsions are behaviours done to prevent a feared outcome or relieve anxiety. While there is a close relationship between onychophagia and OCD, it is not always clear if nail biting is a symptom of OCD, and it may be related to other disorders such as anxiety or ADHD.

Onychophagia, or chronic nail biting, is a compulsion that may cause nail destruction
The line between "normal" and pathological nail-biting is not always clear. According to the DSM-5, a BFRBD triggers clinically significant distress, interferes with functioning in at least one important life domain, and is characterised by repeated, failed attempts to stop the behaviour. Individuals who feel intense negative emotions about their nail-biting, feel unable to stop, and find that it interferes with their lives may benefit from seeking treatment.
Nail-biting is a common behaviour, with an estimated 28-33% of children between 7 and 10 years old and approximately 45% of teenagers engaging in it. It usually begins in early childhood and intensifies during adolescence, often carrying into adulthood. However, the behaviour typically decreases with age and may stop altogether in late adolescence or early adulthood. The prevalence of nail-biting among people in the age range of 60-69 years is believed to be between 4.5% and 10.7%.
There are various physical and psychological side effects associated with onychophagia. Physically, it can cause damaged or disfigured nails and skin, skin infections, fungal infections, and mouth or tooth pain and damage. Additionally, individuals who swallow their bitten nails may be at risk for stomach or intestinal infections. Psychologically, onychophagia can lead to significant distress, social embarrassment, and strained or complicated family and social relationships due to intentional social withdrawal or shaming by others for the behaviour.
Onychophagia can be treated through behaviour modification techniques, addressing any underlying mental health problems or psychiatric disorders, and managing both the physical and psychological factors involved. Treatment options include cognitive behavioural therapy (CBT), habit reversal therapy (HRT), and the use of bitter-tasting compounds on the nails to discourage nail-biting.

BFRB Disorder involves habits related to the body, like nail biting, to relieve tension
Biting one's nails is a common habit, often starting in childhood and continuing into adulthood. While it can be a challenging habit to break, it is treatable. People bite their nails for various reasons, such as stress, boredom, loneliness, hunger, nervousness, or even subconsciously while focusing on a task.
Nail biting is also known as onychophagia, classified as a chronic nail-biting behaviour that usually begins in childhood. It is often regarded as a tension-reducing measure and can be a symptom of an underlying anxiety disorder. In some cases, nail biting can be related to deeper issues such as anxiety or obsessive-compulsive disorder (OCD).
Body-Focused Repetitive Behaviors (BFRBs) are a group of self-grooming actions that can unintentionally harm the body. These include skin picking, hair pulling, and nail biting, among other behaviours. BFRBs are challenging to stop, and individuals may not even be aware they are doing them. They are often done to relieve anxiety and tension and can bring feelings of pleasure or satisfaction.
BFRB Disorder involves habits related to the body, such as nail biting, to relieve tension. It is characterised by compulsive behaviours that can feel irresistible and out of the person's control. While similar to OCD in that it involves repetitive behaviours, BFRB Disorder typically does not involve the obsessions, fears, and intrusive thoughts commonly associated with OCD. Instead, individuals with BFRB Disorder experience a “premonitory urge,” a sudden feeling of tension, which they attempt to alleviate through body-focused habits.
Treatment options are available for individuals struggling with BFRB Disorder, including therapy and medication. Cognitive Behavioural Therapy (CBT) can help individuals reframe their thinking patterns and adopt healthier coping mechanisms. Additionally, self-help strategies such as behaviour blocking, stimulation substitutes, identifying triggers, and mindfulness practices can be beneficial in managing BFRBs.

Nail biting can be a symptom of other disorders, including ADHD, separation anxiety, and tic disorder
Nail biting, or onychophagia, is a common habit, with up to 30% of the population biting their nails. While it is often a nervous habit or a way to deal with boredom or frustration, it can also be a symptom of an underlying psychiatric disorder. In fact, one study found that 100% of boys and 81% of girls who were persistent nail biters had at least one psychiatric disorder.
ADHD
Nail biting is a body-focused repetitive behaviour (BFRB) that is often observed in people with attention deficit hyperactivity disorder (ADHD). BFRBs are characterised by recurrent and chronic behaviours inflicted upon the body, often resulting in physical damage. BFRBs are classified under the ""other specified obsessive-compulsive and related disorder" category in the DSM-5. While research on the link between BFRBs and ADHD is limited, clinical observations suggest a strong connection. Individuals with ADHD may engage in BFRBs as a way to cope with stress, due to poor impulse control, or to self-soothe and focus.
Separation Anxiety
Separation anxiety disorder is another condition that has been linked to nail biting. In a study of children who are persistent nail biters, 20.6% were found to have separation anxiety disorder. While the exact mechanism behind this link is not clear, it is possible that nail biting serves as a coping mechanism to deal with the anxiety and stress associated with separation.
Tic Disorder
Nail biting can also be associated with tic disorders, such as Tourette Syndrome. Tic disorders are characterised by persistent, recurrent, or repetitive behavioural traits that are difficult to control voluntarily. In a study, 28% of children with Tourette Syndrome were found to be nail biters. Tic disorders, particularly those involving the nails, represent an overlap between dermatology and psychiatry, and they can be challenging to manage.

Nail biting can be a coping mechanism to deal with loneliness, hunger, nervousness, or boredom
Nail biting is a common habit, with up to 30% of people doing it, including 45% of teenagers. While it is a widespread behaviour, it does not necessarily indicate a mental health issue. However, it can sometimes be a symptom of an underlying psychiatric disorder. For example, careful scientific studies have found that 28% of children with Tourette Syndrome, a disorder characterised by constant tics, are also nail biters.
Nail biting can be a coping mechanism to deal with various emotions and situations. It is often used to manage loneliness, hunger, and nervousness. For some, it is a way to find calmness in the midst of chaos and overwhelming thoughts. Boredom is another common trigger for nail biting. While not always categorised as a mental health concern, boredom is a universal human experience and can lead to nail biting as a form of self-soothing.
The habit typically begins during childhood and often persists into adulthood. It can be challenging to break, but with the right strategies and patience, it is possible to overcome. Identifying the underlying cause of nail biting is crucial. Talking to a mental health professional can help uncover the root cause and guide towards effective solutions.
In some cases, nail biting can be a manifestation of "just right" or perfectionism OCD. Individuals with this form of OCD may become obsessed with the appearance and feel of their nails, feeling compelled to bite them to achieve a sense of evenness. However, according to Tracie Ibrahim, LMFT, CST, and Chief Compliance Officer of NOCD, nail biting as an OCD compulsion is rare. While nail biting can be a symptom of OCD, it is not typically seen under the OCD umbrella.
To reduce nail biting, individuals can try creating barriers, such as wearing gloves, or replacing the habit with less harmful behaviours. Manicures or at-home nail care can also help deter nail biting, as people may be less inclined to damage their well-maintained nails. Additionally, keeping nails short and neatly trimmed can make them less tempting to bite.

Habit-tic deformity is a form of nail dystrophy that results from external trauma to the nail matrix
Habit-tic deformity, also known as habit-tic nail deformity (HTD), is a type of acquired psychodermatosis that affects the nail unit. It is caused by habitual external trauma to the nail matrix, resulting in nail plate changes. This condition typically arises from the habit of picking or pushing the cuticle backward, often in an unconscious manner. While any nail can be affected, the thumbnails are frequently the primary targets, and involvement of both thumbnails is considered classical.
The characteristic changes to the nail in habit-tic deformity include central depression and transverse, parallel ridging. These ridges run horizontally across the entire nail, creating a distinctive fir-tree shape. Discoloration along the affected area of the nail is also commonly observed. In severe cases, the cuticles may completely disappear, leading to the loss of adhesion of the proximal nail fold to the nail. This exposure of the distal matrix can result in a pyramidal lunula. Constant trauma to the distal matrix can also cause a loss of nail sheen.
Habit-tic deformity is associated with obsessive-compulsive behaviours and may be related to underlying psychiatric disorders such as obsessive-compulsive disorder (OCD), depression, anxiety, and psychotic features. Patients with HTD may experience feelings of relief after nail picking or a sense of compulsion to engage in this behaviour. It is important to note that HTD can lead to permanent nail dystrophy due to chronic nail manipulation.
Effective interventions for habit-tic deformity include physical barriers to picking, such as applying tape or instant glue to the nail folds. Additionally, stress management techniques like meditation, music therapy, and regular exercise can be beneficial. Cognitive behavioural therapy, including habit reversal training, is recommended, along with the suggestion of replacement behaviours such as making a fist or squeezing a stress ball. In select refractory cases, pharmacological treatment with serotonin reuptake inhibitors or other medications may be considered.
While nail biting or onychophagia is often associated with OCD and can be considered a compulsion, it is not the same as habit-tic deformity. Onychophagia is the chronic nail-biting behaviour that usually begins during childhood and can persist into adulthood. It is often driven by stress, boredom, or anxiety and can lead to severe nail damage and psychological distress. However, it is important to note that nail biting is not always indicative of OCD, as it can also be a habit or a coping mechanism.

Frequently asked questions
Nail biting can be a tough habit to break and people do it for many reasons, such as boredom, stress, or nervousness. Sometimes, it can be related to a deeper issue like anxiety or obsessive-compulsive disorder (OCD). While there is limited research on adults, there seems to be a connection between nail biting and OCD in children.
Obsessive-Compulsive Disorder (OCD) involves obsessions and compulsions. Obsessions are intrusive thoughts, images, or urges that cause anxiety or distress. Compulsions are behaviours done to prevent a feared outcome or relieve the anxiety that comes from obsessions. People with OCD feel compelled to perform compulsions over and over again.
If you suspect your nail-biting habit is related to OCD, you may benefit from behavioural treatments from a mental health professional. Cognitive behavioural therapy (CBT) is a form of psychotherapy that can help reframe your thinking patterns and make behavioural modifications. Habit reversal therapy (HRT) is another technique that may help, which involves replacing nail biting with a healthier habit, such as chewing gum.
Consider getting regular manicures to maintain healthy nails and cuticles, which may reduce the urge to bite or pick at them. Using bitter-tasting nail polish can also help deter nail biting. Keeping your hands busy with a stress ball or doing something creative like writing can also help redirect the urge to bite your nails.
Yes, nail biting can be associated with other disorders such as attention-deficit/hyperactivity disorder (ADHD), separation anxiety, and tic disorder. It can also be a form of self-harm used to manage intense emotions and reduce stress and anxiety.
