Compulsive Chewing of Skin: Recognizing Signs, Understanding Root Causes, and Seeking Remedies

Dermatophagia, a lesser-known obsessive-compulsive-like disorder, is characterised by an uncontrollable urge to bite one's own skin. This condition, while not fully understood, has been the subject of ongoing research in the medical community.

If you suspect you might have dermatophagia, it's likely that a diagnosis for OCD would occur first, followed by a diagnosis of dermatophagia. However, it's important to note that dermatophagia isn't well understood, making it difficult for doctors to diagnose.

Treatment for dermatophagia remains a work in progress, but two popular methods are habit reversal training and decoupling. Habit reversal training, a four-part approach, includes awareness training, competing response practice, habit control motivation, and generalization training.

Decoupling, another treatment method, involves diverting the repetitive behavior and creating an irritation. A revised decoupling protocol that integrates imagery into the diversion techniques has shown promising effects.

Common signs of dermatophagia include the urge to eat one's own skin, the desire to bite one's own skin, gnawing or chewing on one's own skin, bleeding and discoloration around hands or nails, and thickening of skin around bitten areas. Biting due to dermatophagia can lead to skin infections and diseases of the nails.

Research from 2021 suggests that habit reversal training has been highly effective for body-focused repetitive behaviors, including dermatophagia. A 2022 research study also supports this, suggesting that skin biting or chewing behavior could result from anxiety, obsessive-compulsive disorders, or depression.

Dermatophagia may be associated with conditions such as Alzheimer's disease, intellectual disabilities, and autism spectrum disorders. It's also worth noting that individuals with dermatophagia may be more likely to engage in other body-focused repetitive behaviors, such as trichotillomania (hair-pulling), dermatillomania (skin-picking), and onychophagia (nail-biting).

In a recent study from 2022, researchers including Dr. Smith found a connection between dermatophagia and anxiety, obsessive-compulsive disorders, and depression. For education and support regarding dermatophagia, consider visiting The TLC Foundation for Body-Focused Repetitive Behaviors.

In conclusion, while dermatophagia is a complex condition, understanding it is the first step towards seeking treatment and managing the disorder. If you suspect you might have dermatophagia, it's crucial to seek help from a healthcare professional.
