10 Causes of Orthostatic Hypotension
Reviewed: Dr. Gromatzky
Cause #1: Low Blood Volume
Low blood volume or hypovolemia occurs when there is blood loss, loss of plasma, and loss of sodium and intravascular water. These symptoms can be seen in bleeding, blood donation, severe burns, diarrhea, vomiting, and dehydration. Symptoms of hypovolemia include headache, profuse sweating, fatigue, nausea, and dizziness. There can also be orthostatic hypotension.
Hypovolemia can be treated by controlling the bleeding or compensating the deficit of blood volume using intravenous fluids, blood, or blood substitutes.
