Onychophagia (nail biting)

Onychophagia, commonly known as nail biting, is a habit of biting and chewing the nails, cuticles, or surrounding skin. It is a form of a body-focused repetitive behavior (BFRB) .

Nail biting is a common habit, especially in children and teenagers. It can be caused by stress, anxiety, boredom, or simply as a habit. However, it can also be a sign of an underlying mental health condition, such as obsessive-compulsive disorder (OCD).

Onychophagia can have several negative consequences, including damaged skin, infections, and damaged teeth. It can also cause social stigma and embarrassment for the individual, leading to a negative impact on their self-esteem and confidence.

Treatment for onychophagia may include cognitive-behavioral therapy (CBT), habit reversal training (HRT), and COMB (Comprehensive Model for Behavioural Treatment). Strategies such as applying bitter-tasting nail polish, keeping nails trimmed and filed, and engaging in alternative activities such as fidget toys or stress balls can also be helpful.
