Bit of an odd one, and wasn't exactly sure where to put this.
Last night after dinner I was in the shower with DH (not doing anything other than showering, was pregame for a nice bath) and after about 15 minutes my vision went blurry and I grabbed his arm and said "I'm going to pass out". I don't know what happened after that but I hit the deck pretty hard and he moved quickly to get me out of the shower, and I remember "waking up" and crawling to the toilet because I thought I was going to be ill. Thankfully I wasn't physically sick or I probably would have called NHS 24, but I was faint and lightheaded for about an hour after getting out of the shower.
Does anyone know what this would have been? I'm in my twenties and no prior health conditions that I know of other than being a bit chubby. I have been getting a bit faint in the shower recently but I usually have enough time to hop out, whereas this time I fully lost consciousness.
(Not looking for expert medical opinions, just interested to see if anyone has had a similar experience and if it led to any diagnoses or medical conditions)
