General & Family Physician,  's  Response
Hi.
There are several reasons that one may pass out or lose consciousness.

The common reasons involve the heart and the blood supply. When one stands up suddenly or when there is a sudden stimulation of the vagus system, blood would move away from the arms and head and move to the legs.

This causes pooling of the blood in the legs and may present with tingling and numbness. One would start to feel dizzy as the blood supply to the brain reduces. After this, one may faint or lose consciousness.

To confirm this, one would need a turn table test to confirm if changes in the body position would cause one to faint. Once confirmed, the doctor may suggest medication or suggest that you get up slowly to prevent episodes of fainting. Avoiding prolonged standing may also be useful.

Hope I have answered your query. Let me know if I can assist you further.

Take care

Regards,
Dr. Vignan Rachabattuni
