Shock-Main causes, types and after effects

Shock is a condition characterized by a discrepancy between the circulating blood volume and the capacity of the vascular tree. It is of various types.

What are the causes of shock?

  1. Hypovolemic shock: it is due to loss of blood or fluid from the body. Thus it can be hemorrhagic or due to fluid loss.
  2. Hemorrhagic shock: whenever there is severe bleeding and the victim is not treated appropriately, the circulating blood volume falls significantly, and the patient develops shock. Such hemorrhage may be seen in the following conditions.
  • Severe injuries.
  • Obstetric hemorrhage.
  • Gastrointestinal hemorrhage due to diseases.
  • Bleeding disorders.
  • 3.Hypovolemic nonhemorrhagic shock: it is seen in cases that lose a lot of water from the body, as in tack: it is due to poor function of the heart, as after myocardial infarction.
  1. Neurogenic shock: it is due to dilatation of the blood vessels much more than the volume of the circulating blood under the influence of nervous activity. It is seen in the following conditions.
  • Severely painful condition.
  • Acute fear.
  • Hearing distressing news.
  1. 6. Endotoxic shock (septic shock): it is due to the action of endotoxins from bacteria in serious infections. These endotoxins cause dilatation of blood vessels. It is seen in the following conditions.
  • Septic abortion
  • . Kidney infections
  • .Septicemia: spread of infection in the blood.
  1. Anaphylactic shock: it is due to a severe allergic reaction to a foreign protein like injected substances or drugs. There is a sudden release of vasodilator substances into circulation, which cause shock.
  2. Metabolic shock: it is due to metabolic and endocrine diseases, such as the following.
  • Insulin shock.
  • Hypoadrenal shock.
