As usual after your expect advice as doctor is away.
About 6 months endo suggested checking Ferritin due to extreme tirdeness and hairloss. Ferritin was 25 at time - range (20-250) doc said normal 😡endo said waaaay to low so I started ferrous sulphate 200mg a day.
3 months on, ferritin improved to 54 and so did my tiredness.
However, another 3 months on and it's DECREASED and now down to 41???
WHATS GOING ON?
Nb: I am convinced I have fructose malabsorption (doc says IBS😡) if I'm right could this be causing me to not absorb vitamns?
