Yeah, I’ve had long-standing ferritin issues since hypothyroidism( not other iron tests which are fine ). Yes, low ferritin, hypothyroidism and menopause all have similar symptoms although over time I’ve developed a way of identifying the differences for me. It is also true that hypothyroidism, untreated or poorly managed, can be the cause of low ferritin due to an issue with something else that I’ve forgotten the name of right now, that may affect the ability to store iron. Even when I had iron infusions I didn’t get my ferritin up much because my thyroid condition wasn’t treated.
In my opinion, based on studies I’ve read and some experts explaining, I don’t think our ferritin needs to be that high at all. There is always, always, conflicting info on this kind of thing, and when I look at studies I try and look at the study design and compare with other studies to figure out what makes sense to me. After years of stressing about my ferritin, after discussing it with the various specialists I’ve seen, I’m happy if I’m between 30-60. I don’t want to be higher than that, lower and I get symptoms. I’ve tried everything anyway and I cannot get it higher than 45 and now I don’t want to. My husband has same diet and lifestyle and his is 110, which actually concerns me and I’m keeping an eye on that.
