Taking too long to recovery from iron deficiency (without anemia)
I know its ironic to ask about something not involving anemia in an anemic subreddit but i am sorry i am not sure where to put it.
When i was a teenager i had symptoms like brainfog, being bad at studies, motivation problems, heart palpitations, hair thinning etc but when i couldnt diagnose it because i wasnt anemic and no doctor bothered to check my ferritin.
Fast forward many years around 6 years and the symptoms persisted but i learned to live with it and at around age 21 i got a ferritin test and it was severely low (5.84ng/ml) and i started supplementing ferrous sulfate, in 4 months i got upto 40ng/ml but then i was impatient and had my doctor give me an IV (500mg ferric carboxymaltose) and 3 months after that i retested ferritin and it was 500ng/ml ! which is above normal range but it wasnt threatening.
its been now 6 months post IV yet i have only had minimal improvements, i did have improvements but they were very subtle and minimal, is this normal? should i test something else? should i wait more? its freaking me out.
If anyone has more questions i will specify
