    Defecation syncope is not a distinct condition but may result from various underlying health issues. Patients experiencing this type of syncope require thorough medical evaluation to identify potential causes.

    Area of Science:

    • Cardiology
    • Gastroenterology
    • Neurology

    Background:

    • Defecation syncope lacks prior clinical descriptions in medical literature.
    • This study investigates a subgroup of 20 patients experiencing defecation syncope.

    Observation:

    • Patients ranged in age with varying episode frequency; many experienced syncope while recumbent or asleep before defecation.
    • Diagnostic evaluations revealed gastrointestinal problems, cardiac diseases, transient ischemic attacks, and orthostatic hypotension in some patients.

    Findings:

    • No identifiable cause was found in 11 patients, with new medical issues noted in four.
    • Recurrences of syncope were observed in half the patients over two years, often unrelated to defecation.
    • Seven patients died from underlying chronic diseases during follow-up.

    Implications:

    • Defecation syncope is likely not a singular entity but a complex interplay of pathologies and physiological changes.
    • Comprehensive medical assessment is crucial for patients with defecation syncope to diagnose and manage contributing illnesses.
