Causes Of Orthostatic Intolerance

Inadequate Fluid And Salt Intake

The body must be properly hydrated for effective blood circulation and blood oxygen levels in the body. When the body is dehydrated, blood vessels constrict and limit blood flow throughout the body, which also causes blood pressure and heart rate to lower. This means the heart is pumping less blood to the organs, tissue, and muscles, and the body is receiving less oxygen. A decrease in oxygen or a decrease in blood pressure can cause many issues, including nausea, lightheadedness, and diminished cognitive ability.

Salt has been associated with cardiovascular issues, but in proper amounts, it is essential for good health. Those who drastically restrict their salt intake may experience an increase in hormones and lipids in the blood, disrupting the volume of blood plasma needed for proper body function and tissue health. When salt levels reach low points, blood pressure also drops, which can cause lightheadedness and fainting. If changes are made to one's diet, it is important to not have inadequate fluid and salt intake.
