MY HEART BEAT VERY FAST AND THEN I GET SHORTNESS OF BREATH AND A BIT DIZZY. WHAT SHOULD I DO. DOE THIS HAVE ANYTHING TO DO WITH LOW HB OR ANEMEA?

Yes can be anemia. Your heart beating fast can be related to anemia and there is a simple test for that. Your heart can beat fast from exercise, and medications, or even nerves. But if it beats so fast that you get dizzy you should see a doctor and have a heart rhythm check. Sometimes this is something that can happen periodically and that can be tested with a monitor. I would suggest having this checked. .
