Severe dehydration can lead to which of the following conditions?

Severe dehydration can lead to kidney failure due to the significant reduction in fluid levels within the body, which hampers the kidneys' ability to filter waste from the bloodstream effectively. The kidneys require adequate hydration to perform their filtration role; when fluid intake is inadequate, or when there is excessive fluid loss (due to things like sweating, vomiting, or diarrhea), the kidneys can become compromised. This situation can progress to acute kidney injury or even acute kidney failure if not addressed promptly, highlighting the critical importance of maintaining proper hydration levels for overall health and organ function.

While sluggishness, fatigue, and nausea can also result from dehydration, they are typically symptoms that can occur at milder stages of dehydration, whereas kidney failure represents a more severe and life-threatening consequence that can arise from prolonged or severe dehydration.
