Unusual deaths associated with polyphagia.

J S Barnhart, R E Mittleman

    The American Journal of Forensic Medicine and Pathology
    |March 1, 1986
    PubMed
    Summary

    Abnormal eating patterns, including pica and polyphagia, can cause fatal asphyxia by physically impairing vital air exchange. Autopsies and detailed histories are crucial for investigating these unusual eating-related deaths.

    Area of Science:

    • Forensic Pathology
    • Toxicology
    • Gastroenterology

    Background:

    • Eating disorders encompass qualitative (pica) and quantitative (polyphagia) appetite derangements.
    • Ingested materials can act as physical agents, compromising cardiac and respiratory function.
    • Mechanisms of injury in these cases resemble those from violence or severe natural disease.

    Observation:

    • Three cases of asphyxia with unusual etiologies related to abnormal eating are presented.
    • Case 1 involved subdiaphragmatic viscus expansion, impeding lung volume and venous return.
    • Cases 2 and 3 demonstrated infraglottic asphyxial loci.

    Findings:

    • The primary mechanism of death in all cases was physical impairment of vital air exchange.
    • These fatalities resulted from complications of abnormal eating patterns.
    • Sudden organ expansion and airway obstruction were key factors.

    Implications:

    • Thorough investigation, including detailed history and autopsy, is essential for diagnosing these rare fatalities.
    • Understanding these mechanisms aids in differentiating accidental, natural, or potentially violent deaths.
    • This research highlights the critical link between disordered eating and potentially lethal respiratory compromise.
