I AM A 54 YEAR OLD FEMALE AND HAVE HAD THE SAME THING SINCE I WAS A SMALL CHILD..ALSO MY DAUGHTE DOES THE SAME THING. WE HAVE WHAT THEY CALL RENEGADE REFLEX...VASOVAGAL REFLEX. IT IS NOT A SIGN OF SERIOUS HEALTH PROBLEM.. THIS IS HOW IT WORKS..LEG VEINS DILATE AND BLOOD POOLS IN THEM, ESSENTIALLY DRAINIG THE CIRCULATION OF A LARGE VOLUME OF BLOOD. THE VASO PART OF VASOVAGAL REFLEX. THEN THE VAGUS NERVE KICKS IN WHEN IT SHOULDNT.. THEHEART SPEEDS UP TO KEEP BLOOD CIRCULATING TO THE BRAIN. HERE THE VAGUS NERVE SENDS SIGNALS TO THE HEART TO SLOW DOWN. EXACTLY THE OPPOSITE ACTION OF WHAT IS NEEDED. THATS THE VAGAL PART OF VASOVAGAL REFLEX...WITHOUT ENOUGH BLOOD REACHING THE BRAIN, THE BODY SLUMPS TO THE GROUND. A PROTECTIVE MECHANISM. THENTHE BLOOD GETS BACK INTO CIRCULATION.SOMETHING IT COULD NOT DO IF A PERSON REMAINED STANDING. THEN THE PERSON REVIVES. I HAVE SUFFER A VERY LONG TIME WITH THIS. THIS MIGHT BE WHAT YOUR DAUGHTER HAS. LIKE I SAID IT NOT A SIGN FOR SERIOUS HEALTH.. ITS JUST SOMETHING THAT HAPPENS THAT YOU CAN NOT CONTROL.. WHEN I GET SICK IS WHEN THIS HAPPENS TO ME. I HATE IT BUT THERES NOTHING I CAN DO...HOPE THIS HELPS YOU SOME... I BELIEVE IT IS INHERITED BECAUSE MY DAUGHTER HAS IT ALSO.. SHE STARTED WITH IT AT THREE YEARS OF AGE AND STLL DOES IT..SHE IS NOW THIRTY.. GOD BLESS, HOPE THIS HELPS. SOMEONE WHO CARES AND UNDERSTANDS. BARBARA
