Useful Notes on the different Types of Shock

Shock may be due to excessive loss of blood as occurs after internal or external haemorrhage, head injury, chest injury, dehydration due to severe diarrhoea or vomiting, burns, electric shock, poisoning, severe bacterial infection (bacteremic shock), a severe allergic reaction (anaphylactic shock), overdoses with certain drugs like narcotics or barbiturates, or emotional shock due to personal happiness or sadness. Sometimes shock may result from a combination of any of these causes.

Shock is a very serious condition and if not handled promptly and properly may lead to death. So prompt and efficient first aid treatment is of paramount importance.
