Dizziness and fainting

[Joycemarie528]

My 17 year old son started having spells of getting dizzy and then passing out, when he comes to, he is out of sorts and the last one fell and hurt his back.  Also he has a history of nose bleeds, the doctor tells me this is due to allergies.  The nose bleeds did stop for awhile and then these spells started and the nose bleeds have started again.
I would appreciate any feed back you might have.

If his Dr says it’s allergies then you should look into this. An allergic response is an inappropriate reaction (exaggerated response) of the body's immune system to a substance that is normally harmless to the body. The offending substance is called an allergen. Initial exposure to the allergen leads to the production of specific antibodies. These antibodies attach themselves to body cells (such as mast cells and basophils that form part of our immune system). On subsequent exposure, the allergens can then bind to the sensitised cells by bridging the antibodies, like a key fits into a lock. Once unlocked, the mast cells release histamine and other inflammatory chemicals. These chemicals are responsible for such symptoms as inflammation, swelling, redness, itching, dilatation of blood vessels, constriction of the airways and increased mucus secretion.  Typical allergic reactions include; asthma, hayfever, sinusitis, swelling of the throat (anaphylaxis), hives, eczema, migraine headaches and abdominal bloating and cramping. Allergies are related to poor liver function, which reduces the liver's efficiency in cleansing the blood of toxins (such as antibodies and chemicals).  Such toxins overstimulate the immune system causing it to pour out inflammatory chemicals (histamines, etc) which may cause;  itchy rashes, hives, etc. In my opinion, and I am not a doctor, but my belief is that if you help detox the liver which needs to be done multiple times, again based on personal research and personal experience. I am partial to a certain cleanse but I don’t want you to think I’m trying to push or sell something. I pray you are receiving some direction with all the responses. God bless

Did he have an ACTUAL testibular testing done or did the ENT doctor just check his eyes? When a person goes through this test it is VERY detailed, it's not just having your eyes checked. Sometimes, teens have problems with passing out and there is no reason found for that happening, I hope that that is the case for your son. Sometimes they can have arrhythmia problems that can cause them to pass out, which could be another reason behind what is happening. See if he can wear a 72 hour Holter Monitor or even an Event Monitor for 30 days. The difference between the two is the Holter will record his heartbeat straight for the 72 hour and the Event monitor he/or someone nearby would have to hit the button to record what is happening at the time he passes out. Have they even done an EKG (although that may not have caught the problem if it wasn't happening at the time)?

He was checked by an ENT, the hearing ,eye reactions and balance all came out okay, we are now getting an MRI and X-rays the next step is a cardioligist.  When this happens he just gets dizzy and blacks out, falls down and when he comes to he is disoriented, does know waht happened.  he doesn't say anything about lossing his hearing.

Hello again. If your son is dizzy, as you described, then it's probably not do to any heart problems as those are a reason for being light headed as opposed to having vertigo, which is what your son has. Ask your doctor about having him go through a testibular testing. I'm taking it that he is having problems with balance as well due to the vertigo. The test will check his hearing as well as his eye reactions and balance. It might be worth a try. The thing that doesn't make sense is vertigo will make a person sick to their stomach, but really doesn't make them pass out. Passing out is caused by a lack of blood flow to the brain which would be a heart related issue. Does he lose his eye sight or hearing just before he passes out? And in which order does he lose it, if he does? Does he ever feel like he is about to pass out, maybe with his hearing being 'off' or things getting dark? Has he been evaluated by a pediatric cardiologist yet?

Hi, thanks for your help, he is dizzy (spinning of the room) and we did have his ears checked by an ENT, and everthing is fine.  I also forgot to mention that he have lost 10 lbs. in the past year.  An his nose bleeds were under control, he hadn't had one in awhile, but has had two in the last week.

Have you had his CBC checked to see if he is anemic? Especially, if he has nosebleeds. (I'm considering a nosebleed like my daughter used to have where there is blood everywhere and he has to have pressure plugs put into his nose  to help stop the bleeding) There are many reasons for a teen to pass out; anything from too low blood sugar to low blood pressure. Dehydration can also cause someone to pass out. One question I have is he dizzy or lightheaded? There is a huge difference and it would help to know which he is actually having as one can be caused by ear problems, the other by low blood pressure.
