Which type of shock is caused by loss of circulating fluids?

• A. Hypovolemic shock
• B. Cardiogenic shock
• C. Anaphylactic shock
• D. Neurogenic shock

Answer: (A)

Loss of circulating fluids causes hypovolemic shock. When intravascular volume falls, venous return drops, reducing preload, stroke volume, and cardiac output, which leads to inadequate tissue perfusion. This type of shock is typically due to hemorrhage, severe dehydration, burns with fluid loss, or gastrointestinal losses. The body responds with tachycardia and vasoconstriction to maintain perfusion, but blood pressure often declines as volume depletion worsens. Other shock types involve different mechanisms: cardiogenic shock stems from the heart’s inability to pump effectively; anaphylactic shock from widespread vasodilation and capillary leak; neurogenic shock from loss of vascular tone due to spinal injury. So the description fits hypovolemic shock because the primary issue is loss of circulating fluids.
