“He bit himself” can refer to accidental self-inflicted bites, emotional or sensory-related self-harm, or a medical condition like dermatophagia.

Reasons range from a toddler’s frustration or sensory needs to a compulsion in older individuals.

For children, it can be a developmental way of coping with strong emotions before they have words to express them.

In some cases, it can be a symptom of an underlying neurological or psychological condition, and the behavior should be addressed by a healthcare professional.
