What causes sudden fainting?

i vomited Sunday night, then i guessed i passed out because my husband said he heard me fall and got me up. I have NO recollection of it, but did go to hospital for several tests to check out. Not a stroke, but thought that the vasal-vegas (s.p.?) nerve caused it. Okay, but what are chances of recurrence and what should i watch out for?

Hello,

Vasovagal syncope occurs when you faint because your body overreacts to certain triggers, such as the sight of blood or extreme emotional stress.

So, to avoid recurrence you should avoid these triggers.

Recurrence rates can't be predicted.

Hope I have answered your question. Let me know if I can assist you further.

Regards,
Dr. Erion Spaho, Neurologist, Surgical
