1 Dehydration can sometimes cause blood pressure to drop. 2  However, dehydration does not automatically signal low blood pressure. 3  Fever, vomiting, severe diarrhea, overuse of diuretics and strenuous exercise can all lead to dehydration, a potentially serious condition in which your body loses more water than you take in.
1 Low blood pressure, also called hypotension, is blood pressure low enough that the flow of blood to the organs of the body is inadequate and symptoms and/or signs of low blood flow develop shock.2  Low pressure alone, without symptoms or signs, usually is not unhealthy. These symptoms are most prominent when individuals go from the lying or sitting position to the standing position (orthostatic hypotension). 2  Low blood pressure that causes an inadequate flow of blood to the body's organs can cause strokes, heart attacks, and kidney failure.
