Ischemia/reperfusion can trigger which systemic condition?

Ischemia/reperfusion can trigger which systemic condition?

• A. MODS
• B. MI
• C. Stroke
• D. Hypoglycemia

Answer: (A)

Ischemia followed by reperfusion can ignite a body-wide inflammatory response that damages multiple organs. When blood flow returns, reactive oxygen species, pro‑inflammatory cytokines, neutrophils, and complement activation surge, injuring the endothelium and increasing vascular leak. This systemic inflammatory cascade impairs microcirculation and perfusion across several organs, leading to dysfunction in the lungs, kidneys, liver, heart, and gut—collectively known as multi-organ dysfunction syndrome. While localized ischemia underpins conditions like myocardial infarction or a cerebrovascular stroke, and hypoglycemia is a metabolic issue, the systemic consequence of global ischemia/reperfusion is MODS.
