I have on and off for the past couple of years i will just black out where i get really dizzy and lightheaded and my vision goes black where i cant see anything its not like i have a migrane cuase my head doesnt hurt. I used to think it was nothing until i went to the Kottonmouth Kings Concert and blacked out during it and had to sit in the bathroom for the rest of the concert, i have blacked out a few times since but it was nothing serious and then today i was taking a shower with my boyfriend and had to get out cause i couldnt see and could barely walk almost completely fainted i couldnt even think straight i could hear him talking to me but i wasnt totally there.

i know my family has some history of heart problems in it and things like this worry me so much.

    If this has been happening for years I wouldn't panic. I bet you passed out from the crowd at the concert and you were hot, like in the shower. I agree it can be low blood sugar. My sister faints whenever she has a medical procedure, not matter how minor. My whole family faints. I fainted once on a subway and went to the doctor and he said I had fluid in my ears and to take cholortrimiton or some allergy pills. It seemed to work. I would get checked too though, just to see if he has a better idea.

    There are a number of things for you to think about. Have you had your blood pressure checked? Too high or too low of blood pressure can cause fainting. Are you on any medications? A number of medications can throw your pressure off whack or cause fainting when changing positions from sitting to standing. There are also disorders that are not harmful but cause random fainting spells. Either way, I would be concerned enough to make a visit to your family physician. You need some tests run, especially with your family history. Get an answer so you can stop worrying and start doing something about it!

    OK, first if you need a medical opinion, get to a doctor.

    Second, you can have migraines without pain.

    But if sounds like one of two things to me. Because it happened in the shower, it could be dehydration. It used to happen to me a lot if I got the flu or a cold cause I only drank sodas, etc. Try drinking half of your weight in ounces a day - so if you weigh 130 lbs, you would drink 65 ounces of water a day - that's 2 big nalgene bottles, or about 5 regular sized store bought bottles.

    Second, it could be low blood pressure - that was happening to me for a while and once I got it under control with medicine it stopped right away. Try standing up and sitting up slowly too and see if that helps at all.

    Go see the doctor this week and tell him what you have told us. He might give you a halter monitor that you press a button when you are having a "spell" so he can see what is going on with your heart when it happens. He might do an EKG to see if your heart rhythm is normal. It could be a thyroid problem, or your blood sugar could be off. It is hard to say at this point, but blood tests among other things will help your doctor get to the bottom of it.

    What's happening to you could be due to a number of things but getting a diagnosis from the internet is a very bad idea. It could be something as simple as low blood sugar or it could be a brain tumor. You need to see a doctor as soon as possible so you can find out, once and for all, what is causing this. Good luck!! : /

    Blacking out/fainting for no reason is not good. Do you eat properly? (thinking low blood sugar-hypoglyemia). take meds, drugs? I would not be so much worried about heart as neurological. But who knows. I think this is serious enough to see a Dr. about - You could black out driving. Have an aneurysm. I suggest you get checked out -

    If you haven't gone to a doctor, you should..while it could be dehydration, it could be something much worse or even something underlying to cause the dehydration. Make an appointment with your doctor, if it isn't anything horrible at least you went it and found out what it was. Better to be safe then sorry later

    go to a DOCTOR.

    brain needs sugar to metabolise and oxygen and others to keep working and active. if any reduction in these you faint.

    blood loss -can lead to anemia and one can faint if he does more work and less nutrient and rest to brain.

    blood flow reduction to brain by vaso vagal phenomenon- causes faint.

    blood circulation restriction to brain due to heart problems can lead to fainting spell

    heart arrhythmia's- leading to temporary stopping of blood supply to brain can cause fainting

    blockage in teh carotid arteries, which is a route to brain cause fainting

    fits can present as fainting

    and many more. so go to a doctor.

    This used to happen to me and I'm pretty sure that it was because I was dehydrated. I had not been drinking enough fluids throughout the day. After I started drinking more water it stopped.
