It's very good that your on top of this. I am a male and my Hg went to 8.5 (normal 14-18). I felt very tired, etc... I corrected it with OTC iron tablets for 6 months but it will never correct if one never stops flaring. I get my iron, B12 and folic acid checked once a year just to keep an eye on everthing. My iron levels dropped to 24-30 at one point so I know what you are talking about. 6 is crazy low. Good luck with this. Remeber that even though your numbers will normalize you should keep taking iron to build up your stores in the bone marrow. That usually takes 6 months after the numbers are normal.
