Thyroid and low haemoglobin

I have been reading this forum but this is my post. I am in 200mcg of Thyroxine and still feel pretty dreadful and have researching on this forum about how to improve.

However last week, I went to donate blood and (for the third time) was refused due to too low haemoglobin - so low they told me to go to the GP.

So here I am... The GP ordered a FBC and has shown the following to be low -

Haemoglobin concentrate 104 g/L (120-150)

Mean cell haemoglobin 23 pg (27-32)

Mean cell volume 77 fL (83-101)

Also Harmatocrit 36% (36-46)

My TSH level 3.1 & T4 15.1

I haven't spoken to my GP yet - he sent me for ferritin blood test today.

So I think my question is, I'm obviously aneamic - do you think the years of symptoms that I assumed were due to my thyroid were in fact due to aneamia?

Thank you so much for your reply. Ok so the anaemia is due to the thyroid....

When you so I'm under medicated do you mean thyroxine?


Personally I stopped donating blood as soon as I discovered I had Hashimoto's ....I had been regular donor, but would hate to pass anything on.

Not sure what Blood service policy is on autoimmune diseases
