Hmm... You are describing two different situations, actually.
First, as to the ordinary blackouts. I have had them all of my life... Sometimes 1 or 2 on the same day, but generally weeks or months in between. This usually occurs when I have been sitting or lying down, and am relaxed.. Then I get up quickly and maybe stretch. Usually I just get a little dizzy, sometimes vision closes in and I go blind. Generally it clears away within a couple of seconds, but there have been a few times I wound up on the floor, and only 2 times I went fully unconscious. I think this is caused mainly by the body responding slowly in raising my blood pressure when I stand.. Depriving the brain of blood for a couple of seconds.
As to the situation when she was getting a tattoo... I did tattooing for many years and that is a common occurrence. Usually people get a little "psyched up" before getting a tattoo. They are anticipating possible pain, are nervous, and this triggers an adrenalin response. Pain further triggers adrenalin release. However, the person has to sit very still, usually under a warm light, listening to the drone of the tattoo gun. The body does not have the opportunity to burn off the adrenaline, and it causes a blood pressure drop. There is no predicting who it will happen to. I did a tattoo on a guy who had full sleeve tattoos.. He had had LOTS of tattoo work before. Then for some reason, when getting this one tattoo.. I noticed he looked pale and felt clammy. I told him to take a break.. He got up, took two steps, and fell flat on his face. He said he had never had it happen before, and most of my customers have commented that my tattoos do not hurt as much as most tattooists do (most tattooists go WAY deeper than they need to).
