Dallas nutritionist discusses fainting causes and fighting it. Â Fainting is a temporary loss of consciousness followed by a usually rapid recovery to normal functioning.Â Â Never the less, fainting can be concerning.
Normally, fainting is caused by a lack of blood flow to the brain.Â Because the brain does not store energy, it requires a constant supply of sugar and oxygen.Â Â A short period of no blood flowÂ causes the brain to go into an energy-conserving shutdown mode.Â This causes a cessation of impulses to nerves and muscles and the victim slumps to the ground.
Non-cardiac causes are generally triggered when the signals between the brain and the vagus nerve are crossed.Â The vagus nerve regulates blood pressure and heart rate.Â Because of some trigger, the vessels in your legs relax and blood pools in the legs, making it difficult for the heart to pump enough blood to the brain. There are many triggers for non-cardiac fainting including but not limited to emotional stress, fear or pain.Â Some people faint when rising from a chair or getting out of bed.Â Dehydration which causes less fluid can trigger a faint as can eating, which draws extra blood to the stomach and intestines in order to aid digestion.
Cardiac realated fainting can be caused by a rhythmic problem.Â The heart may beat to slowly or too quickly.Â Any obstruction that effects the blood flow through the heart can lead to fainting.Â These obstructions could be a clot or tumor.Â A severely enlarged heart or a tear in the aorta or damage to the heart muscle can also cause fainting.
If one is fortunate enough to get a warning that he might faint, there is a method that may help to ward off the faint.Â Squating and tensing the legs can help to get the blood pressure back to normal levels and avoid an episode.Â Sitting or lying down may help.Â Crossing the legs and tensing the muscles in the lower body whileÂ clasping your hands behind your back and pulling is another option if the victim is alert enough.
There is also a preventative method called tilt training wherein one stands 6 inches from the wall and leans against the wall for 3 to 5 minutes twice a day. Add a minute or two every few days until this position can be held for 20 to 30 minutes without feeling faint.Â After that, this should be done 3 or 4 times a week.
While fainting is generally harmless, but disconcerting, one should always discuss it with a physician, as it could be a warning of a potentially dangerous heart problem.
