Has anyone ever passed out suddenly without much warning, only some lightheadedness. All blood, brain & heart tests came back normal. Any ideas?

  • If you are male then I have to ask if you are wearing shirts with collars that are too small, tight or do you wear your necktie too tight. This has caused some men to pass out.

  • similar thing happens with autostatic hypotension/intolerance. You feel a whirring sound in your brain - feels like all the blood leaving your head, feel lightheaded then suddenly pass out. Comes on if stood up for too long, after a heavy meal, etc

  • My teenage son did this off and on for over 2 years before we finally got into Texas Children's in Houston. It got to the point he was "blacking out" five times a day...no real warning signs and when he did pass out it was just for a few seconds....He "blacked out" during the exam and we ran lots of tests but it was diagnosed as BAM's - basilar artery migraines....He had 11 out of all the other symptoms but never at the same time. It occurs mostly in teenage girls but can occur in about 25% of males with migraines....It's pretty scary but with medication, it's almost completely gone away....

  • Please see a cardiologist about possibly having Prolonged QT syndrome. It is a heart arythmia that can be difficult to detect. Mine was detected only after cardiac arrest. I had a history of "passing out". Please get checked.

  • I am very interested in learning more about these "black outs". Did they occur after he had the migraines? How did he discribe the feeling? My husband had been experiencing similiar. What medication did they put your son on? He had an episode in the Neurologist's office last week. The Dr. has never seen anything like this. He has had a series of tests. From Cardio to all the Neuro tests. Nothing shows up on those. My teenage son did this off and on for over 2 years before we finally got into Texas Children's in Houston.

  • Did they do a cortisol check??? If the adrenal glands were to be going it would cause black out spots.

  • has anyone here passed out for very long periods of time? My son has been doing this for 1 year...usually out for at least an hour, sometimes up to 2 hours. We have been to many, many dr's...still no answers. These usually occur with physical activity, although last week, just while standing

  • One time back in March/April of 2006, I passed out while working on my computer. I had several tests: MRI, CT with/without contrast, blood work ups, etc. All was negative for any condition or disorder.Over time, I developed more symptoms. I was initially diagnosed with Atypical Migraine.Seven months later, I was diagnosed with Narrow-Angle Glaucoma and treated with laser surgery. I haven't had a symptom since my diagnosis.

  • I've been passing out cold ever since I was 14. People used to think that I was doing it for attention, but it soon came to a stop when I passed out in the middle of the street. As of now (27), I am still passing out and doctors haven't a clue as to what could be going on. I'm surprised that I do not have any broken bones! Praise God, He always has His angels around me!!

  • Has anyone ever passed out suddenly without much warning, only some lightheadedness. All blood, brain & heart tests came back normal. Any ideas? I first experienced this when I was 12 or 13. I was sitting in a barber's chair on a very hot summer's day. About half way through the procedure I felt slightly dizzy, then passed out. I woke up out of the chair and covered in perspiration. Scary for the people around me, but once I woke up I was perfectly OK (if a little tired). I'm 53 now and have been living with it ever since. The cause was never diagnosed as all my vitals were perfectly normal whenever a doctor would check me out. I never knew when it would hit. Always with a minor injury (not significant injuries, like broken bones, I'd stay awake for these) like jamming a finger in a door. Occasionally it would happen for no apparent reason: sitting on a train, shopping, just walking around. Once I'd had an episode I'd be right for months, maybe a year or more. I've been a long distance runner since I was 18. About 5 years ago I started suffering headaches if I skipped a run for a couple of days. A couple of years ago I was diagnosed with hypertension (140/120). I was prescribed Coversil (don't know the chemical composition) which includes a diuretic and have a blood pressure of 120/70. Since starting the medication two and a half years ago, I've had no headaches (unless otherwise ill with a cold or something) and no blackouts. My theory is that the medication regulates the highs and lows. The highs were causing the headaches and the lows the blackouts.

  • Today I passed out in history class. My eyes started rolling in the back of my head, and then I saw double vision, after that I think I passed out in my seat and then it took like 5 minutes for my history teacher to wake me up.

  • i faint, 20 times this month, anything from a few minutes to over four hours. often i wake up slowly, my eyes open but unresponsive for a few minutes to half an hour. Then i start to come round. I'm often weak after and can't walk for half an hour to a few days.It could be caused by orthostatic hypotension (low blood pressure) which could be general or postural (occurs after standong up). It could be cardiac, caused by a bundle branch block, or a slow or fast heart beat. It could be caused by secreased oxygen levels from breathing too fast or too slow. It could be from

  • ANSWER: You CAN pass out if you place your Laptop computer on your belly while laying down in bed. What happens is the pressure from the laptop on your belly affects the blood-flow on the "Inferior Mesenteric Vein" located on your belly, This would affect blood flow to your brain and cause you to get lightheaded and pass-out for up to a minute, several times and can cause temporarily mild memory loss. Its rare in overweight men, But does affect pregnant women.
