Answer 98, views. It would be a good idea to see your GP and make sure there is nothing that could be causing this. It may be vasovagal syncope, which is a common cause of fainting, when your body over reacts to certain triggers. Often this can occur if people get a fright, such as the sight of blood or emotional triggers.
Your heart rate and blood pressure drops meaning you get less blood flow to your brain causing you to faint. Vasovagal syncope is usually harmless and your GP will check that there are no other problems.
