Though sounding like a term from a science fiction novel, autocannibalism is a real phenomenon with psychological and cultural implications. It involves an individual consuming parts of their own body. This behavior, while rare, has been observed in various contexts throughout history, from religious rituals to extreme mental health disorders.

Autocannibalism manifests in different forms. Some may engage in self-mutilation, such as biting or cutting off parts of their body, while others may actually consume the flesh or tissue. This behavior can be driven by a range of factors, including mental illness, cultural practices, or extreme situations such as survival scenarios.

Psychological perspectives

Autocannibalism is often associated with conditions like psychosis, schizophrenia, or severe forms of self-harm disorders. It may stem from distorted perceptions of reality, delusions, or a profound disconnect from one's own body. In some cases, a person may experience intense compulsions or intrusive thoughts driving them to engage in such behavior.

In a study, researchers looked into autocannibalism as a consequence of traumatic brain injuries (TBI). It remains unreported in literature but may be linked to psychosis, intellectual disability, or substance abuse. 

A recent case involved a 35-year-old male with a TBI history, presenting with self-inflicted wounds. The case highlighted the need for long-term psychiatric and neurological follow-up post-TBI to address emerging self-destructive behaviors and improve patient outcomes.

Medical concerns and risks

Engaging in autocannibalism poses significant medical risks, including severe infections, tissue damage and potential complications from ingesting non-digestible materials. Additionally, the underlying mental health issues driving this behavior require professional intervention and treatment to address the root causes and prevent further harm.

While autocannibalism remains an unsettling behavior, understanding its various manifestations and underlying factors is crucial for both mental health professionals and society. By recognizing the complexities surrounding this behavior, efforts can be made to provide appropriate support and intervention for people struggling with such impulses, ultimately promoting their well-being and recovery.
