It is really unfortunate that you have pernicious anemia
, the only solution is iron supplements
which you have to take life long. Ask your GP for easily absorbable iron tablets which increases the gastric uptake. Low Hb along with hypothyroidism
makes you exhausted and sleepy all the time. If you have not got a thyroid profile recently make sure you do one and visit the endocrinologist
to up your medicines if required.
I hope you found my response to be helpful and informative. If you have any additional concerns I would be happy to address them.
