Hi John E, Cannot disagree with your observations about the sunlight being a possible contributing factor. I'm sure we all have seen others in out life, ot have heard of people passing out in the "parade ground" situation. It may well be that in your case, sunlight may be a more significant factor, but it is not for me. in fact, I cannot recall any instances occurring in exceesive heat or sunlight.

As for bowel movements, my specialist suggested two possibilities, one being that when unconcsious, the sphincter relaxes and therefore the motion is involuntary, second, that the body goes into an automatic survival mechanism, and in order to be prepared to defend itself, and make itself more efficient to flight, evacuates it's bowel, and in the case of those who vomit, the unnecessary contents of the stomach. Interesting theory. Certainly my experience is that I have had no bowel or stomach distress before the VV episode, and have had no urge to pass a motion until the VV episode is well progressed and I have been lying down for some time (Minutes I would say), and then I feel that happen.

Not withstanding all the above, John, I do recall once in the middle of the night where I went to the toilet and had a serious dizzy spell which I now know was an episode. No food, but I was a little constipated, and the effort was greated than normal.

As you have seen from the contributions to this forum, the episodes are many and varied. I offer these as my experiences and how I have understood or interpreted them. Yours could well be as you have experienced yours. I know that reading yours have made me think a little more ly of my episodes which is good, and I thank you for that.

Kind regards

John L.

pre attack warning signs

From: Blanche


I am a 41yr.old female smoker just diagnosed with veso vegal. I have had two episodes and prior to each of them I had a sudden feeling of exhaustion then I felt dizzy then my head started spinning the next thing I knew I was being picked up off the ground/concrete. This all happened in a three minute time frame. Does anybody else have prior warning signals or do they just pass out?

Vasovagal Episode

From: Carole


I am 45 years old, general good health, very hyper and stressed type of personality (female). About 4 weeks earlier, reclining at home watching television, felt a heat and pressure sensation in my head, mainly forehead, very hard to swallow, felt I had to make myself breathe, cold sweats, shaky, ....if I didn't make myself breathe and try to move, almost pushing myself, I felt I would lose it. Upon coming out of it, I was extremely shaky....swallowing started to get easier, couldn't keep my eyes open, very, very heavy and shortly afterwards a headache that lasted for hours. It is very scary and has happened several times to me since the first, all presenting with about the same symptoms. It is very scary and I don't know what to do or how to pull out of it. I have not fainted, but it is like I am stepping out of my body but have to step back into it or something terrifying is going to happen. It is very frightening. I have my first referred doctors' appointment for this condition next week....I hope there is something I can do for this.
