Hypovolemia is a reduction of the volume of the blood circulating in the body. At the base there may be bleeding or loss of body fluids other than blood data arising from diarrhea, vomiting or excessive sweating. Hypovolemia can however also be caused by severe burns, use of diuretics or by insufficient fluid intake.

The first problem is dryness of the mouth, nose and other mucous membranes. The skin loses elasticity and the production of urine decreases. If the loss of blood or fluids is not adequately compensated you can get the hypovolemic shock, a condition that occurs when you lose one-fifth of the volume of blood. At this point symptoms like cold sweats, pale skin, rapid breathing and heart rate, weakness, anxiety, confusion and loss of consciousness may appear.
