A common cause of shock is significant blood loss, also known as hemorrhagic or hypovolemic shock. Other common causes include severe allergic reactions (anaphylactic shock), heart problems (cardiogenic shock), infections leading to sepsis (septic shock), and physical obstruction to blood flow (obstructive shock).
Common Causes of Shock
- Hypovolemic (Low blood volume): Severe bleeding from trauma, internal injuries, or dehydration.
- Cardiogenic: Damage to the heart muscle, such as from a heart attack.
- Distributive: Severe infections (sepsis), allergic reactions (anaphylaxis), or nerve damage affecting blood vessels.
- Obstructive: Conditions impeding blood flow, such as pulmonary embolism or cardiac tamponade.
Among these, the most frequent cause overall is hypovolemic shock due to hemorrhage or fluid loss.
