Septic shock is categorized as which type of shock?

• A. Obstructive shock
• B. Distributive shock
• C. Cardiogenic shock
• D. Hypovolemic shock

Answer: (B)

Septic shock is distributive shock. It happens when infection triggers widespread inflammation that causes blood vessels to dilate and become more permeable. This dilation and leakage redistribute blood flow and reduce the effective circulating volume, so tissues don’t get enough perfusion even if total blood volume isn’t low. The heart may still pump, and volume can be adequate, but the vessels are too large and leaky, leading to poor tissue perfusion. This contrasts with obstructive shock, where a physical blockage prevents blood flow; cardiogenic shock, where the heart itself can’t pump effectively; and hypovolemic shock, where there is an actual loss of blood or fluids.
