What is a dangerous hb range? mine is 6, i eat a healthy diet and i have been on mirena (levonorgestrel) with no periods for years?

Hgb <8: A hemoglobin of 6 is very low. There are many causes of anemia including bleeding (seen or unseen=occult), vitamin deficiencies, and lack of production from bone marrow problems. Initial workup includes (at least): complete blood count (CBC) with differential, reticulocyte count, EPO level, peripheral blood smear. Additional studies from there...

See doctor: If your hemoglobin is really 6, you really need to see a doctor or hematologist immediately to figure out why. There are many causes of anemia (low red blood cell number), some very serious. You are approaching a dangerous range with respect to your hemoglobin.
