What causes light-headedness?

Question

At work I have to squat down and stand up often. When I stand up I get a head rush or light-headedness. Other people I've asked don't experience this. Could this be to poor circulation or smoking, or what?

Answer 1

Iron deficency test: Go to the mirror and pull your lower eyelid and see if the color is red or flesh color. If its flesh colored you are lacking enough iron and should take a herbal iron like Floradix. It will take a month to see a difference. Iron carrys oxygen in your blood and if you dont have it you will feel tired, cold hands and feet, headaches, RLS, dull brittle hair, brittle nails, poor sleep, pale skin (see thru), shortness of breath, fatigue, poor concentration, low mood, ringing in the ears, irregular heart beats, cracks in the corner of the mouth, dizziness, fainting, sore tongue and canker sores. Add b12 and folic acid for best results
