Hi all, I don't have hypothyroidism but my thyroid is beginning to struggle (see previous posts) and as a result I am having absorption issues. I was anaemic in March and had a ferritin level of 8. I posted my last blood test results 8 days ago as my ferritin and B12 had dropped by over half in about 2 and 1/2 months after stopping supplementing when the anaemia was sorted out.
Ferritin June - 111 (13-150)
Ferritin Sept - 55 (13-150)
I'd also had a FBC and my serum iron levels were well within range (all slap bang in the middle of range) but I'd started having symptoms again and didn't want to slide back into anaemia and have read that ferritin needs to be at least 70 for the thyroid to function well. Anyway, I still had some ferrous sulphate (200mg) tablets left so have been taking one a day for the last 8 days. A few days ago I started getting mild stomach gripes. Yesterday I spent the whole day in pain with really nasty stomach cramps that had me doubled up and I felt really sick and generally tired and lethargic. The cramps and nausea kept me awake for a lot of last night. I still feel pretty horrible this morning and am afraid to eat anything.
Could I have overdosed on iron in 8 days? Should I not have taken iron when my serum iron was fine? I'm hoping it's a bug but the extreme nature of the stomach cramps are making me worried.
