Dizziness Causes & Orthostatic Hypotension Why Do I Get Dizzy
Sometimes When I Stand Up? When standing quickly, it may take a
second or two for the body to make adjustments to constrict
blood vessels and push blood up to the brain. If there is a
delay, then this time of relative low blood pressure may cause
symptoms. It can be exacerbated or seen more often in women who
are pregnant, people with diabetes, those who become dehydrated,
or are taking high blood pressure medications. Symptoms include
of dizziness upon standing (orthostatic hypotension) include: -
nausea, and - fainting or passing out. There may also be
weakness, blurred vision, and shaking or tremulousness. These
symptoms may resolve quickly as the body slowly adjusts to the
standing position, but in some cases the person has to sit or
lie down quickly to prevent passing out or falling.
