There are five main types of shock, including septic shock, anaphylactic shock, cardiogenic shock, hypovolemic shock and neurogenic shock, according to MedicineNet. Septic shock occurs when bacteria multiply in an individual's blood and release toxins, causing infections in the urinary tract, skin and abdomen, as well as pneumonia and meningitis.
Anaphylactic shock is the result of a major allergic incidence, often from medication, consumption of certain foods or contact with certain insects, explains MedicineNet. Cardiogenic shock is the result of damage to the heart that limits the body's ability to pump blood, such as from a heart attack. Hypovolemic shock involves blood and fluid loss, including through major injury or anemia, and neurogenic shock occurs from spinal injuries.
