Profuse sweating is another symptom of hypovolemic shock, though it is considered a fairly mild one. The severity of symptoms will depend on and coincide with the amount of blood or fluid lost. Some symptoms are more urgent than others, but mild symptoms like this one should still not be ignored or brushed under the rug.
Profuse sweating goes beyond the body ridding itself of excess water after rigorous activity or in the hot weather. You know your own body and when it is natural for you to sweat. If sweating comes about suddenly and is soaking through your clothes or bedding, you can be convinced it is not due to natural causes.
