+**Hypoxia** is a critical condition where the body, or a specific region, is deprived of adequate [Oxygen](/wiki/oxygen) at the tissue level. This deficiency can profoundly impair cellular function and, if severe or prolonged, lead to significant organ damage and even death, often resulting from issues in [Circulation](/wiki/circulation) or gas exchange. It represents a fundamental threat to life processes that rely on consistent oxygen delivery.
