What is the most common underlying cause of MODS?

• A. Sepsis and septic shock
• B. Dehydration
• C. Hypothyroidism
• D. Hyperglycemia

Answer: (A)

MODS happens when the body's response to a severe insult triggers widespread inflammation and poor tissue perfusion, leading to progressive dysfunction in several organs. The most common underlying cause is sepsis and septic shock, where a systemic infection sets off a cascade of inflammatory mediators that cause widespread vasodilation, capillary leak, and microthrombosis. This disrupts oxygen delivery across the body and drives organ injury in the lungs, kidneys, liver, heart, and other systems. Dehydration can worsen perfusion but is not the typical driver of MODS, and while metabolic disturbances like hyperglycemia can accompany critical illness or hypothyroidism can complicate recovery, they are not the usual initiating cause. Sepsis, therefore, remains the primary trigger behind most MODS cases.
