Dehydration is a lack of adequate fluid in the body. Dehydration is a dangerous complication of various infections, and can be especially dangerous to infants and the elderly. Hot weather or excessive exercise or exertion can contribute to dehydration. Dehydration is a concern with any condition causing high fever, diarrhea, vomiting, or blood loss. Insidious forms of dehydration can arise in undiagnosed diseases such as internal bleeding, diabetes mellitus, diabetes insipidus, and kidney failure. Dehydration can cause dangerous electrolyte imbalance, and can even be life-threatening. Treatment is by replacement of water along with special drinks to replace lost electrolytes (salts, glucose, etc.), or hospitalization and intravenous fluids in severe cases.
