In brief: Syncope

Most probably a sudden drop in blood pressure.
Your blood pressure needs to be checked sitting and standing to see if there is a drop. One simple maneuver you can try is to stand up with your head down then gradually bring your head up.

In brief: Fainting

When you feel like you are going to pass out after a sudden change in position, you could be experiencing a rapid drop in your blood pressure.
This can be due to dehydration, anemia, medication problems, heart problems, or other issues. You should be seen by a physician to have this evaluated and get some blood tests run.

In brief: Blood flow

Benign condition such as transient orthostatic hypotension refers to a drop in blood pressure that occurs with the position change of either lying/sitting to standing.
Standing causes the blood in the body to move downward due to gravity and pool in the legs. This results in decrease blood to the brain and a sense of fainting. Medications can also cause similar symptoms. Please see your doctor.
