Try webmd.com I'm sure they can tell you what you need to know for a fact.\nGuessing, I'd say it's due to a lack of blood to the brain while standing or under stress or shock. When they hit the floor and are laying down, it allows the blood to flow easier and it gets to the brain again and they wake up again.

First of all, learn how to type the english language.\n\nWhen you feel dizzy, sit down immediately.  If you're really hot, try to cool yourself down.  Get something cold to drink, like water.\n\nGo see a doctor.  \nI've been fainting all my life so I'm used to it.  Since it's only been happening to you for a month, you need to go see a doctor because something could seriously be wrong.

It's called orthostats, try this...  Lie down and relax for about 10 minutes and then take your pulse.  Slowly stand up and then after a minute take your pulse again.  If there is a huge difference, say more than 20 beats, you're probably dehydrated...

Get the victim out of the water if you can do so safely. \nMonitor for breathing and pulse. If no breathing and no pulse, do CPR. If no breathing, but there is a pulse, do rescue breathing.If victim is breathing and has a pulse, put him or her in the recovery position. This position keeps the airway clear and allows swallowed water or vomit to drain. \nTake cold, wet clothes off the victim and cover him or her with something warm to prevent hypothermia.Get Emergency Care and give first aid before emergency care:

Dizzyness can be caused be many things.  One of the most common is low blood surgar, the other is being anemic.  If you are passing out completely is could be a seizure.  It sounds like you might just have low blood sugar or could be anemic you should ask your doctor about the symptoms and they can give you a better answer.

People that faint in the face of danger, are suffering from a suddenly and significant drop in blood pressure.\n\nFainting is actually a valuable self protective response.When blood pressure drops this way, there is a chance the brain won't get enough blood, because it's at the highest point of the body. That's no good - your brain needs a steady supply of the oxygen the blood carries. So when your body can't get enough blood to your brain because of low blood pressure, it protects you by bringing your brain down to the blood. In other words, the purpose of a faint is to ensure a blood supply to the brain by bringing your head down to the ground, so your heart doesn't have to overcome gravity.

That is called orthostatic hypotension.  Actually, it is because the blood is rushing out of your head that you are dizzy.  This can be the result of a number of medical problems, or developing problems, including anemia and hypothyroidism.  It can also have something to do with not drinking enough liquids or not enough salt.  Your diet may very well be contributing to it.\n\nNow, as for the question about splotches of white, you are indeed on the way to passing out.  The pressure sensors (called baroreceptors) trigger your heart to pump harder, but they don't always catch things in time.  It is possible to pass out from this condition.  It's best to get up slowly.\n\nTalk with your doctor about it.  This is something that should be taken care of before you get hurt with it.

Definitely Consult a doctor.\n\nHowever... most fainting is as a result of lack of BLOOD FLOW.  This may seem WEIRD... but it's a technique that ASTRONAUTS use and TEST PILOTS\n\nSometimes, due to EXTREME Velocities.. the blood rushes from their brain.  If you think it's EMBARRASSING to black out when your scared... it can be DEADLY to these guys.\n\nHere is a technique.. and I'm NOT kidding.. or being disrespectful.. what they do... when they feel they are getting LIGHT HEADED... is CLENCH their BUTT CHEEK as hard as they can.  (I mean it)... there is a lot of blood in the tissue... that gets infused into your blood stream when you do this.\n\nIt add as much as a few ounces and increases your blood pressure momentarily... maybe long enough to remain conscience...  These TEST PILOTS do it all the time.\n\nI know it sound strange... but it really works.\n\nPLEASE see a doctor.  At 14, nobody should be blacking out.\n\n&tan

Good question. You need to find out quickly.\nThere are many causes of black outs or syncopal attacks. \n\nThe most common is a vaso-vagal attack which is induced by stress or fear among others. This is the usual fainting episode most people would have witnessed.\n\nFainting or blackouts can also be associated with urinating, pressure on the neck from clothing etc, some heart problems and it could also be the result of prolonged standing. Soldiers sometimes suffer from this on parade grounds.\n\nThere are a few other causes but the best answer in the light of the above is to see your doctor because he is equipped to find out why and show you what you could do about it.

It may be a vagus nerve disorder rather than cardiac.  Go to the internet and read about vaso-vagal fainting to find further information.

Schedule an apointment with a doctor. So far, it sounds like the flu. However, if he does actually pass out, or he gets any more symptoms that make him seem worse, you should go to the ER as soon as you can. This could be a sign of something more serious than just the flu. Until then, get plenty of rest and lots of fluids. Try giving him some pieces of banana also if he has been throwing up. He might need potassium.

Generally common in young people , but low blood pressure is vague term, importantly if your blood pressure is generally low and you are asymptomatic, that means its not causing you any problems, only thing your doctor can advise is to increase caffeine/salt intake, But low blood pressure which has come on suddenly and causing you dizziness and fainting needs to be investigated by your doctor. In nutshell, if you have low blood pressure and no symptoms, consider yourself lucky and maintain healthy lifestyle, if on other hand, its come on recently and its giving you problems, you need to see doctor

If you feel like you are going to pass out, many times it is due to a sudden loss of blood pressure, like from getting up from the couch after watching a movie. \n\nYou will feel light-headed, or slightly dizzy.\nImmediately take a breath and force it slowly out.  In other words as if blowing up a strong balloon. This will tighten up your diaphragm, and raise your blood pressure, hopefully in time to prevent passing out.\n\nI have heard anecdotal stories that coughing really hard may also help.  Same principle, it creates pressure in your upper diaphragm, thus temporarily raising blood pressure.
