When I came back from Italy this happened a few times when I stood up from watching TV lying down. It stopped, but I'd like to know what this means.

Thanks everyone.

  1. This has happened to me, it never used to but it started happening when I was 14. I would take a few steps after laying down on my bed watching thee television and then sort of gradually my eye sight would darken but I could still manage to see, it still happens and I'm now 18.

    The worse was when I was in high school and we had been standing for a long time for the start of the new year, sorting out classes and getting time tables etc but not only did my eye sight darken to the point where I couldn't see nothing but black but while the principle was talking over the mic, my hearing had also begun to sort of weaken, I've never passed out before so I don't know what it's like but I was wondering if I was about to, that was two year ago. It was also very hot that day so maybe it is just dehydration like that other person said but the other times that it happened weren't hot days at all.

    I live in Australia, Sydney and have never traveled to Italy, let alone to another country so that's got nothing to do with it.


  2. Due to the liquid stuff in the ears that helps with balancing. Serious. If you get up to quickly it doesn't have time to level out.

    Balance depends on visual information, "feedback" from muscles and from an inner ear structure called the semicircular canal. The semicircular canal is a set of 3 fluid-filled canals that are aligned at right angles to each other. Within parts of the semicircular canal are hair cells. When the head is moved, the fluid in the canals moves the hair cells and a nerve impulse is generated in the vestibular nerve.

    Of course you know that if you spin around in circles you will get dizzy. But do you know why? When you spin, fluid in the semicircular canals of your ear moves around. This stimulates the hair cells. When you stop spinning, the fluid still moves a bit. Because the fluid is still activating hair cells, your brain stills gets a message that you are moving and you feel dizzy.

    same as when you suddenly stand up. The hair cells need to adjust.

    Balance, or one' s sense of equilibrium, is controlled through the vestibular system that is also contained in the inner ear. The vestibular organs share the temporal bone space with the cochlea. These organs also share the same fluid that is in the cochlea.

    Balance and equilibrium help us stay erect when standing, know where we are in relation to gravity, and help us walk, run, and move without falling. The functioning of the vestibular system depends on information from many systems, hearing as well as vision and muscle feedback.

  3. Don't stand up so quickly.

  4. You may have low blood pressure, which isnt very serious but if you're having full on black outs it's probably best to have a check up at your doctor. They often advise people who have low blood pressure to increase the amount of salt in their diet, however this may not be the reason you have low blood pressure or are getting dizzy. if it gets worse or continues for along time you should get checked out.  

  5. I have this problem and I went to the doctors to find out if there was anything wrong but they told me it could be due to High or Low blood pressure.Either way don't worry it's not life threatening..:)

  6. it could have been something in your system from Italy.. or maybe you weren't eating enough nutrients

  7. It happens to me all the time, usually from being fatigued.  I've also heard it's from being dehydrated.  Not sure if that one is true or not though.  :)  Don't worry, you're fine.
