Is nail biting a mental issue?

Biting your nails (onychophagia) isn't always a disorder; it can be a common habit linked to stress or boredom, but chronic, severe nail biting is classified by the APA as a body-focused repetitive behavior (BFRB), falling under "Other Specified Obsessive-Compulsive and Related Disorders" in the DSM-5, similar to skin picking or hair pulling, especially if attempts to stop fail despite negative consequences. It's considered a disorder when it causes significant distress or impairment, often occurring alongside anxiety, OCD, ADHD, or depression, though not everyone with these conditions bites their nails, nor does everyone who bites their nails have a disorder.
