For the past couple weeks I ve been plagued with bouts of lightheaded ness, nervousness. It last anywhere from a few minutes to maybe 5 or 10. Previously I was put on iron supplements but have since stopped. I have a rather large fibroid that does not cause pain but I m wondering if it could be the culprit. I m on a bp medication (lisoprin sp?). My ac1c was 6.1 but it was indicated that iron deficiency could cause it to be increased. Tomatoes seem to help as well as taking Allegra D. I m also into menopause so uncertain if that could be the cause too.
