### input:
I have a question if someone can please help me, at age 17 I became pregnant off of the birth control yaz. at the time of my pregnancy I became very ill, getting dissy spells, fainting and losing my sight to spotty and blurred vision from a few seconds to a almost a minute. i never got checked out by a neurologist but my obgyn believed I had been experiencing episodes of epilepsy . after birth it stopped. now im 21, and when I have occasional drinks recently up to a certain point in the time frame while I am drinking I black out and am still awake and functioning to a certain limit but friends have said that s I complain of pain in my body like a major headache or telling them I feel exhausted and weak while im blacked out but they always thought I was just dehydrated. ive even thrown up and right after im incoherent, cannot speak or are not able to walk and a few minutes after thati fall asleep and I don t wake at all until the next morning they ve even thrown water on me and I would not wake up. my breathing and heart still beating they just assumed I passed out but the next morning Im completely confused because I can only remember up to a certain part of the night and after I cant recall anything at all. im wondering if maybe im having an episode of epilepsy which causes me to black out while im under the influence

### output:

Hello, The earlier episodes you describe of dizzy spells & grain of vision could be due to Syncope or pre syncope. The episodes are brief & lasting few seconds to a minute. The more recent episodes could be seizures or syncope. The prolonged period of unresponsiveness, lack of memory for the previous nights events and other accompanying symptoms raises the possibility of seizures. Visit a neurologist who will be able to perform an EEG, Brain imaging & other tests which can help in confirming the diagnosis. A cardiac evaluation for any cause of blackouts is also necessary. Hope this helps.
