Hypovolemic shock The most common cause of shock is severe blood loss. If the blood loss exceeds 1.2 litres (this is about one-fifth of the normal blood volume of an adult), shock may occur. The blood loss may occur due to external and/or internal bleedings. Loss of other body fluids can also result in shock. Conditions that cause heavy fluid losses include diarrhoea, severe burns, etc. Cardiogenic shock In addition, shock may occur when an adequate volume of blood is available, but the heart is unable to pump the blood around. This problem can be due to severe heart diseases, heart attack or acute heart failure. Other types of shock Other causes of shock include overwhelming infections (septic shock), lack of certain hormones, low blood sugar level (hypoglycaemia) (metabolic shock), under-cooling (hypothermia), injuries to the respiratory track or lungs (respiratory shock), severe allergic reactions (anaphylactic shock), drug overdose or spinal cord injuries (neurogenic shock).
