Black out? Hypertension? Blood pressure change?

[anki_gos]

I am a 23 yr old female. I have been experienced a sort of 'black out' of late. This hasnt happened often, though... just 4 times till date. The first time was when i was about 19, I suppose. I dont remember exactly.
What happens is initially I start feeling a bit 'off' like slight light headedness. This is followed by increasingly blurred vision (a colourful one) and a pressure in my ears, which after a certain point results in total loss of hearing and I lose consciousness for a while.. say about 5-10 seconds. I sweat a lot and cant control my movements for a while..
The last time this happened I was slightly intoxicated, but all other times I was completely sober.
I'd never really taken this seriously but now i'm beginning to wonder if i should. Please advise.

Hi, Thank you for your question. Your symptoms might be due to postural hypotension or vasovagal syncope. This is triggered by stress, sudden onset of extreme emotions, sudden standing-up, prolonged physical activity with hyperthermia, and even seeing non-pleasurable event etc. This pre-syncope (like lightheadedness and dizziness) is very early stage of syncope which may last for few seconds to minutes and can be prevented by early interventions measures like lying down, elevation of legs, deep breathing, immediate glucose drink and inhalation of any stimulant like spirit of ammonia etc. Please arrange an appointment with a neurologist who will evaluate the further prognosis here and can provide you an appropriate treatment. Hope this helps.
