I just had a pap smear and afterwards felt like i was going to pass out and got nausous.. not my first pap, why did this happen?

Hypotension: When you have a procedure like this, an automatic message goes into the brain. The brain processes this message to decide whether some form of adjustment is necessary. This is how we adapt to any form of stress. Because the processing by your brain was abnormal, your adaptive adjustment was also abnormal. The easiest way to do this is by poor diet, particularly the intake of sugar and sweeteners.
