Today, my company conducted an initiative for employee health welfare, wherein a thorough physical and biochemical examination of each employee would be done.
There were a series of non-invasive tests conducted (parameters noted) for each employee (height, weight, body fat, visceral fat, BMI etc). I was more or less within 'normal' range, except for the blood pressure which was 103/72. And, when it came to blood tests, I fainted (literally blacked out) as soon as they pricked me for drawing blood. I didn't remember anything thereafter, until I woke up to the scene of whole staff surrounding me (I was made to lie down on the floor with my feet elevated). After waking up, I was back to normal (feeling little drained off energy though).
Upon some research I found out that it is Neurally Mediated Syncope (also referred to as vasovagal syncope or a vasovagal response) wherein one's blood pressure drops abruptly, and brain doesn't receive required amount of oxygen to stay active. Triggers are often anxiety/ emotional distress,or even a sight of blood during the blood draw (for me I wasn't looking at the blood being drawn; anxiety/ stress is something one can't be conclusive about).
I hope there is nothing serious associated with it. Anyone experienced similar episode?
