    Causes, incidence, and risk factors

    Losing about 1/5 or more of the normal amount of blood in your body causes hypovolemic shock.

    Blood loss can be due to:

    • Bleeding from cuts
    • Bleeding from other injuries
    • Internal bleeding, such as in the gastrointestinal tract

    The amount of circulating blood in your body may drop when you lose too many other body fluids, which can happen with:

    • Burns
    • Diarrhea
    • Excessive perspiration
    • Vomiting
