Mine was 18, but I know it went below that as I was becoming short of breath in the 2 weeks after the blood test.
I lost about half the volume of my hair in about 6 weeks.
Extremely tiredness and some days would fall asleep during the day.
Becoming out of breath very easily, even just sitting still I would have moments where it would feel i had been holding my breath,and after walking up the stairs.
I only realised after the iron kicked in (took about 1-2 weeks) but I had barely been smiling, because I was constantly so wiped out.
As someone who always felt the need to go out everyday, I was suddenly very content staying at home. Certainly not normal for someone in their mid thirties!
Running around became plodding around. I'm really annoyed my OH didn't flag to me sooner, because i think at the time it's far more obvious to someone else than yourself.
Started taking fumerous ferate, and honestly the difference is astonishing. I feel like sonic the hedgehog, it's quite scary how a person can steadily go downhill and not realise until half their hair has gone!
My doctor has been useless, I've had to self medicate, in his eyes my result was classed as normal. Anyone with a brain could put two and two together and see it was causing my symptoms.
I've pushed them for a stool sample test to rule out any internal blood loss , that is probably going to be the most I'm going to get. Anything else I will have to go privately for they said.
For now it seems, I will just continue on with the iron supplements and have no idea what will happen if I stop....
