This type is very specific to the person that is why when such situation comes, it is best to stay away from it to prevent fainting.

2.       Postural fainting- this happens when a person who suffered from dehydration, severe blood loss, medication side effects and a lot more experiences syncope after changing from one position to another. One main example of this is when a person who lies on bed for a long time abruptly stands up and faints. This is so because there is a blood pressure drop thus causing insufficient flow of blood to the brain. It is important to sit first on the bed before fully standing up to give time for the brain to have sufficient supply of blood.
