What is it?

Hypovolemia is a term describing a situation when your body loses fluid volume, like blood or water. Fluids are vital to keep your organs functioning. There are many reasons for fluid loss. Losing blood can be due to a trauma or a major surgery, whereas losing water can be due to kidney diseases or low intake.

Signs & symptoms

Symptoms of hypovolemia may include weakness, fatigue, dizziness, dry mouth, pale and cold skin, confusion, unable to pee, and muscle cramps.


Diagnosis of hypovolemia is based on your medical history, your clinical condition, and a physical exam perform by a healthcare provider. Your heart rate, blood pressure, and pulse oximetry may suggest that you suffer from hypovolemia. Laboratory findings like sodium levels and your blood creatinine may also suggest your condition.


There are two routes in treating hypovolemia. One route is to treat the reason - if a trauma is the cause of losing blood then a procedure to stop the bleeding must take place. If a kidney disease is the reason to a water loss in urine then it must be investigated and treated. Simultaneously, the patient must receive fluids - blood or water - that he or she has lost.
