Last night I passed out which I have never in my life done before. I got out the bath, put my bath robe on and as I was walking to my bedroom I started feeling weak and dizzy, had blurred vision and ringing in my ears. I went and sat on my bed with a bin near me as I thought I was going to throw up. Next thing I remember, I was kneeling on the floor not knowing where I was or what had happened. It took me a several seconds before I realised I'd passed out. Don't know how long I was out for but it really shook me.
There could be so many reasons for this and I'm afraid that the account that you have given is inadequate, that nobody could make a reasonable guess as to the cause.
My advice......no need to see a Dr at the moment, just monitor the situation for the next couple of weeks and if there is a recurrence then see your GP.
I've felt faint before after getting out of a hot bath but never actually passed out.
I've also had a couple of days off work and been mostly lounging about and eating leftover buffet food from Monday. I didn't go into work today as I still feel a bit queezy. Maybe I should've drunk more water.
A hot bath makes the blood vessels expand which causes the blood pressure to fall so you got postural hypotension when you got out. Maybe take it slowly and sit on the side of the bath for a few minutes before walking away
tigger......i am not criticising your description, but the fact that it doesn't fit into the picture of postural hypotension.
However your GP will question you more thoroughly.
