What is the medical term for bitten nails?

  1. Onychomycosis

  2. Onychophagy

  3. Onychorrhexis

  4. Onychocryptosis

The correct answer is: Onychophagy

The medical term for bitten nails is Onychophagy. This term is derived from Greek, where "onycho-" refers to nails and "-phagy" means eating. Onychophagy specifically describes the habit of biting one’s nails, which is a common behavioral issue often associated with stress or anxiety. It can lead to damage to the nails, surrounding skin, and even infections if not addressed properly. Understanding Onychophagy is crucial for nail technicians, as it can impact nail health and aesthetics, and may require special care or guidance for clients who engage in this habit. Recognizing the term helps in communicating effectively about nail health concerns and potential treatments or preventive measures. The other terms are related to different nail conditions: Onychomycosis refers to a fungal nail infection, Onychorrhexis describes brittle nails that split or peel, and Onychocryptosis is the term for ingrown nails. Each term pertains to specific nail health issues, but only Onychophagy pertains directly to the habit of nail biting.
