What is shock?
Shock is a life-threatening medical condition as a result of insufficient blood flow throughout the body. Shock often accompanies severe injury or illness. Medical shock is a medical emergency and can lead to other conditions such as lack of oxygen in the body's tissues (hypoxia), heart attack (cardiac arrest) or organ damage. It requires immediate treatment as symptoms can worsen rapidly.
Medical shock is different than emotional, or psychological, shock that can occur following a traumatic or frightening emotional event.
What are the types of shock?
Septic shock results from bacteria multiplying in the blood and releasing toxins. Common causes of this are pneumonia, intra-abdominal infections (such as a ruptured appendix) and meningitis.
Anaphylactic shock is a type of severe hypersensitivity or allergic reaction. Causes include allergy to insect stings, medicines or foods (nuts, berries, seafood), etc.
Cardiogenic shock happens when the heart is damaged and unable to supply sufficient blood to the body. This can be the end result of a heart attack or congestive heart failure.
Hypovolemic shock is caused by severe blood and fluid loss, such as from traumatic bodily injury, which makes the heart unable to pump enough blood to the body.
Neurogenic shock is caused by spinal cord injury, usually as a result of a traumatic accident or injury.
