X50-X57: Overexertion, travel and privation

X54: Lack of water

Lack of water, also known as dehydration, represents a spectrum of conditions characterized by the body's loss of water and electrolytes beyond its intake leading to disruption of metabolic processes. This condition often occurs when your body loses more fluids, usually through excessive sweating, diarrhea, or vomiting, than you take in. Initial symptoms may include dry mouth, thirst, and diminished urine output, followed by more severe signs such as rapid heart rate, lack of sweat, extremely dry skin, and low blood pressure. Dehydration can be severe and immediate enough, resulting in delirium, unconsciousness, and in extreme cases, death. Long-term, recurring bouts of dehydration affect virtually every system in the body including urinary, digestive, circulatory, nervous systems and may lead to complications such as urinary tract infections, kidney stones, and even kidney failure.
