I eat anything. Yes you could be a little over replaced - but your ferritin is low. I was really struggling at 57, tried 3 lots of spatone a day for a month and it went down.
The endo I saw commented it was aclittle low at 57 but felt it would go up - however I was (I now know) over replaced. And this can drain iron too. This at the very least can make food shoot through you so you don't absorb food.
I've been taking 2x 200 mg iron tablets since January; it took 3 months to get to 80 ish, I'm not sure latest. But as my strength and muscles have improved I seem to be needing a little less thyroxine. Periods can be very heavy post baby draining iron as well as simply pregnancy too. You need iron to grow muscle etc, slight over replacement shouldn't be a big issue but could weaken you. Spatone has roughly 14-18 mg in comparison. (The daily amount)
Hair loss can happen post baby but also with low ferritin. In not a Dr, but I've gone through this recently, inc baby! My periods didn't return till 2 as I was bf but they really caused a lot of issues.
I really would look into trying to see which iron tablets you might be able to manage.
Regarding thyroxine, you could adjust by a 25 every other day. Eg 125/150.
But really best to discuss all with gp. I think it's reasonable to ask to try raising your ferritin. I've picked up from mn and elsewhere that 70-90 is best level for ferritin if you are on thyroxine.
And what your stools are like - eg my mil had very pale gassy stools. Have you been tested for other guy issues?
Also, vitamin d?
