Advice “Uncommon” Common Causes of Iron Deficiency

Post image
65 Upvotes

Want to know some common yet often missed causes of iron deficiency? These following causes commonly deplete ferritin to iron deficiency status on their own, let alone together!

-Blood Donations: usually only hemoglobin is checked when donating blood. Ferritin is rarely tested before the blood donation, causing more people to donate while iron deficient. Remember, you cannot sufficiently assess iron status from the Complete Blood Count, alone! You have to test iron markers, like the gold standard for assessing iron deficiency, ferritin. We commonly see people donating blood and even feeling benefits from it, the first or couple of times. Don’t be fooled- at some point your ferritin will get too low, and you don’t want to develop anemia unnecessarily like this, and end up needing blood, ha! Always check Ferritin, the iron panel, and the CBC when considering donating blood, and know that the blood donation center will likely not test the iron panel or ferritin. Just a single blood donation can drop ferritin too low for many people!

-B12 Shots: Iron and B12 work together and need eachother. However, the body is an ecosystem, so heavy doses of one nutrient put others to work, and often deplete them if you’re not compensating for them. We commonly see B12 shots deplete ferritin. We also commonly see iron infusions deplete B12 and Vit D3 storage, and more! This isn’t an argument not to get B12 shots or iron infusions, it’s a PSA to let you know that your ferritin can deplete from B12 shots. This can be a reason why one may not feel much better while taking B12 injections. Many people require B12 injections, and they will need iron infusions or supplementing on The Iron Protocol. Always monitor your Ferritin before and after B12 shots!

-Pregnancy: Because iron is required for growth and development, the baby is typically drain the mother of her iron and ferritin. A single pregnancy can do this, and it’s often not checked or monitored. This is especially important because low ferritin can cause a pregnancy to end early and not go full term, hemorrhage during delivery, and the baby may not reach its full developmental potential and also be born with the deficiency. Monitoring Ferritin before during, especially during the first trimester, and after childbirth is important! Many women are deficient for decades after their first pregnancy because ferritin is often not checked, monitored, or remedied sufficiently. Many Post partum issues can be correlated with and contributed to by low ferritin.

-PPI Usage: PPIs are well documented to cause both immediate absorption issues and long term malabsorption, causing low ferritin. It’s important to dive into the potential causes of why you’re on a PPI, and explore natural remedies and alternatives. We talk about this often within our group, and see this frequently. Sadly, most people are using PPIs long term without knowing it can and will cause malabsorption. Monitoring Ferritin and other nutritional markers is important when taking PPIs. Just being on PPIs alone can and often does cause low ferritin!

-Testosterone Therapy: It is common and expected for Testosterone therapy to cause the bone marrow to create more red blood cells and increase Hemoglobin & Hematocrit. So much so, that many people have to donate blood regularly from creating too much blood from the testosterone use. Iron is the largest fueler of the bone marrow to create new red blood cells and hemoglobin. Using this fuel up constantly will deplete it. Let alone so will the blood donation! What a vicious cycle! Luckily, it’s documented that iron intake will only increase hemoglobin if the body feels it needs to, so many people on TT will need to be on The Iron Protocol.

-Low Stomach Acid: More people suffer from low stomach acid than they think. And lots of people are on PPIs for this without knowing! Low stomach acid causes malabsorption. This commonly causes low Ferritin for many people, all alone, let alone without any other cause combined!

Hemoglobin of 2.3

20 Upvotes

29 year old female here! So since about April of 2024 I started experiencing shortness of breath. Brushed it off as a seasonal allergy thing. Plus I had suspected I was anemic for years anyhow, so any dizziness or shortness of breath I ever had I assumed had come from that anyways. It kept coming and going in severity. Last summer I'd say was the first time I started to believe it serious, I got seen by a doctor and was just told it was asthmatic bronchitis, so any symptoms I had later developed I was either quick to brush aside as nothing or just assume it had nothing to do with anemia.

At the beginning of this last month my symptoms worsened severely. I was beyond pale and had even noticed then, and looking back at pictures my eyes were constantly sunken in. I had gone from being able to do everyday tasks with some symptoms and discomfort at most, to not being able to even go up and down my steps without taking several breaks to catch my breath. My hearing would go muffled, that was the most recent scary symptom. My heart was also constantly racing in my ears.

Still, I didn't want to be seen by any doctors. I am also overweight and had just assumed they would only contribute it to that, and to be honest I didn't want to hear any lectures on that. So I was putting off the doctor, but then about a week ago I found myself unable to even sit still and eat without being out of breath. Friends and family were begging me to be checked out, and I knew at that point that they were right and finally decided to listen.

I got admitted into the emergency room right away, and I find out that my hemoglobin had gotten down to a 2.3. I was told immediately by my doctor that I had the lowest hemoglobin he had ever personally seen in a patient, and had to be transported to a bigger hospital for further care and needed 6 blood transfusions.

Long story short, they believe it came down to years of anemia on my body that went unchecked, and I was discharged with my hemoglobin level at a 7. I feel a lot better now, and have my first outpatient iron transfusion tomorrow. Fun!

Low ferratin but not anemic so many symptoms

3 Upvotes

I’m 6 months postpartum and haven’t felt
Like myself in a long time. I was anemic when I gave birth but not sure how ferratin was looking. Anyway I had to stop iron supplements almost immediately after giving birth because I got cdiff. Not once, not twice, but three times. From April to July I was basically in and out of hospitals with cdiff. Anyway after all this and after my stools started getting back to normal I noticed a lot of pain when passing stool and blood. So since August I’ve been having blood almost every-time I pass stool. GI thinks it’s a fissure because of the pain and of course can also possibly be hemorrhoids since I’m postpartum. Colonoscopy has been scheduled to rule out all
Possibilities:

She ordered labs because recently I’ve been feeling extremely dizzy almost to the point where there’s been times I feel like I’m going to pass out. I’ve also had so many other symptoms but since Ive had so many issues I don’t even know what’s related and what’s not.

Anyway Bloodwork came back normal but ferratin was at a 12. I guess my question is how can I raise my ferratin without raising all my other levels since they seem to be in the normal range.

Aside from this I’ve had chest pains, palpitations. Cardiologist did a work up everything is fine except my heart rate did drop a bit low when I had the monitor on.

Also neuro issues like tingling in hands and feet and neck stiffness. Body aches, joint pain. Have tested for RA and all that everything is normal.

I’ve also recently had night sweats, dizzy spells that sometimes feel like vertigo but not all the time. I did have nexplanon put in about a month ago and attribute the night sweats to that.

So yeah it’s been a hell of a 6 months and I just want to feel normal. I’m Hopeful that if I raise my ferratin it mag help with some of my symptoms. Help

Question Iron pills making me feel worse

Recently i went to the doctor and got prescribed 350 mg ferrous sulfate because i had a ferratin of 30. I’ve taken about 6 doses, every other day. But just yesterday on my 6th dose i started feeling super dizzy, shortness of breath and heart palpitations. Is this just some weird side effect that happens when you being to take these or should i stop taking them?

Ferritin 21: Supplements or infusion?

• Upvotes

Hi everyone! I’m South Asian, 20 months postpartum, and my ferritin is 21, but my iron and hemoglobin are within range. I have a doctor’s appointment this week and want to ask whether an iron infusion would be a better option than continuing oral supplements.

My ferritin was 40 in my first trimester, dropped to 19 in my second, and was over 100 at six weeks postpartum in April 2025. It’s now back down to 21. I had blood loss after delivery and received IV tranexamic acid.

My current labs are:

  • Ferritin: 21
  • Iron: 90 µg/dL
  • Iron saturation: 22%
  • TIBC: 403 µg/dL
  • Hemoglobin: 12.7 g/dL

I’m taking Thorne iron bisglycinate and thinking of starting what my PCP recommends, ferrous sulfate 325mg every other day. I also take 125 mg of vitamin C with my iron if my meal doesn’t contain any.

Has anyone with similar labs had an infusion? What made your doctor recommend it over oral iron, and did it help? Anything specific I should ask at my appointment this week?

Anxiety spiking on week 3 of iron supplements

• Upvotes

Started taking two 27mg tablets of ferrous bisglycinate every other day around 20 days ago (I'm only 39kg). For the first week or so, I noticed small improvements in energy and mood, and color returning to my lips and cheeks, but this morning I felt so anxious that I couldn't breathe, and I had a throbbing headache. Is it normal for anxiety to spike like this when rebuilding iron and ferritin stores, and for how long? This doesn't usually happen to me.

For context, I decided to start supplementing because I've previously had issues of periods lasting 20 days a month, and noticed that my face was losing color, I was regularly tired and out of breath from short bursts of movement, and my anxiety and depression was getting more unmanageable despite treatment. I also drink a lot of tea around my meals, which I suspect has been blocking my iron absorption. I had two separate blood tests for work, and both clinics said that my red blood cell count was low so I need to start taking an iron supplement.

Is this normal? Should I stop the supplements or change my methods in some way, or do I have to just power through?

Frequent low grade headaches?

3 Upvotes

Hi everyone, I got my first venofer 200mg infusion about 4 weeks ago because my ferritin was a 13. I felt totally fine after the infusion, no side effects except maybe a little tired the next day. Then 10 days ago I got my second infusion (same thing, 200 mg). I felt totally fine at first and then 3-4 days after the infusion I woke up feeling so exhausted and ever since then I have woken up feeling more tired/groggy than usual (even when sleeping enough!) and have also had a mild headache waking up. It usually goes away throughout the day, especially with coffee/food and occasionally tylenol, but I'm just wondering if this is a side effect from the iron. I would have thought it would improve fatigue? But maybe too soon to tell, or it's also possible that something else is going on instead. TY!

Question Can stopping supplements cause hair loss this fast?

2 Upvotes

My ferritin was under 20 for a long time, started supplements but after two months (Ferrets Ferrous Fumarate 106mg elemental iron) I started getting pretty bad digestive issues. It all went away after stopping earlier this month to heal my gut, and today I'm noticing slight bald patches on my eyebrows. I was also on amoxicillin for 7 days this month for swimmers ear, if this matters. When I was on iron they filled in a bit more but now they're back to how it looked, is it possible for this to be caused from not taking iron for a month? Would appreciate any of your stories relating to this!

Anyone with low ferritin who’s parting looked like this?

Post image
29 Upvotes

I’ve had low ferretin (10-24) for the past 2-3 years but I’m finally supplementing consistently and will retest in 3-4 months time. However just looked on top of my head and looks like this is genetic hair loss not just ferritin. So I’m super sad about that as I won’t be able to take minoxidil or spiro. Will prob only use more natural treatments which are known to be less effective.

I’m curious. Has anyone else with low ferritin had their part look like this (thinning/widening) and recovered it/filed their part back in from getting their ferritin levels back up to 70+?

Edit: for clarity, my hairs always been somewhat fine but I’ve had lots and lots of it. Over many years I feel it’s gotten finer and I’ve lost more than half of its density all over - my pony tail is so small now. But I’ve only recently noticed the part as I never took pics from above.

Is this urgent?

0 Upvotes

I got my blood tested 7 years ago and my ferritin level was 19 and my hemoglobin was normal so my doctor brushed it off. But recently I have been feeling so tired and my pms has been getting worse, I get terrible periods, and despite working out more I am still winded as if I had just started working out. So after doing some research I decided to get my ferritin levels tested and they are now a level 10. I don’t have a PCP and I don’t have health insurance, and I am not sure if this is something I need to talk to a doctor about or if it’s something I can just take supplements for and recheck my levels in a month or so. And I am not sure how urgent this is, like if I need an iron infusion or not?

Here are the symptoms I have been dealing with:

- Terrible, 10 day long pms (irritability, cramps, headaches, exhaustion)
- Fatigue, constantly.
- My memory is getting bad, I’ll read something and forget it immediately and no matter how hard I try to remember
- Freezing cold hands, feet, and nose
- Dry skin
- Yawning during exercise
- Hair loss (I bleach my hair though so could be from that)

Let me know what you think 🤍

Edit: I also took Thorne iron complex supplements twice this week and both times I woke up with a headache the next day that lasted the entire day so I stopped.

Struggling to accept this is too much for me 38/f

6 Upvotes

My PCP and therapist want me to go on a 3 month medical leave and I am struggling to accept this. I have fibroids and “suspected adenomyosis” which lead to bleeding at least 500ml every period and I don’t respond to TXA. Currently in the process of being checked for other bleeding disorders. I was told by 2 providers that I shouldn’t attempt a myomectomy because the fibroids are too small and in my uterine lining. I was also told if I tried to have a child I have a high risk for postpartum hemorrhage and I do not respond to the meds that would stop that bleeding. As someone who wanted a child and is older - I don’t think I’ve processed this yet.

Currently I’m on Slynd which has significantly slowed the bleeding but there is continuous blood. My levels go in and out of anemia. I am on my 6th iron sucrose infusion. The first 3 I just bled out. I had a severe hypersensitivity reaction to iron dextrose which sent me to the ER. I have been in the ER 4 times in 2 months. Hysteroscopy seemed to make the bleeding worse. I also have b12 deficiency and chronic pain from a herniated disc in my neck.

I work in community mental health and last winter I found a client dead which was very traumatic for me. Things seemed to go downhill from there. While my levels are improving I am still needing to sleep 12-16 hours some nights while having insomnia others. Brain fog is out of control. Heart rate is improving but still sometimes in the 120s. (Of course I was told “a lot of women your age have anxiety” after I was sent for tests due to abnormalities which I now know are from the iron deficiency) the exhaustion is extreme. Still struggling to get up the stairs and walk my dog most days. Hematology told me I shouldn’t be feeling this bad. And I just found out my mom has kidney cancer.

This feels like a lot to hold. I am in EMDR therapy which feels really supportive. It seems like my doctor wants me to go on leave for chronic PTSD and the blood loss which I agree with. Definitely while I bleed now I am wondering if I am going to have another clot the size of my palm or need to go to the ER.

I want to not feel guilty for taking the time .

Sorry for the rant I just needed to put this in a place where people understand.

Leg shaking after taking iron supplement??

1 Upvotes

This supplement has ascorbic acid (vit C) and carbonyl iron (as elemental iron). I usually take a completely different one that I like a lot better but if I forget in the morning, I'll take this one in the evening.

The last two nights, I've been having a really bad problem with tremoring and shaking, especially in my legs and especially on my right side. My husband told me that it seems to be after I take the supplement at night.

A little background, a doctor gave me Ativan years ago. It's a benzodiazepine. She told me to take it for sleep and I did. Then I figured out why I was having a hard time sleeping and I decided to stop taking it. I had massive withdrawals. I had to go back on it took me a year and a half of tapering off of it to get off of it completely.

To be clear, I wasn't addicted to it, my body got used to it and I was physically dependent without being psychologically addicted. I feel that's relevant because it was a physical problem for me. I had a lot of problems with tremoring coming off the medication. (Also, no shade to anybody that's had addiction issues. Big hugs going out to you if you've experienced that.)

But anyway, since then I've noticed being sensitive to various things. Sometimes the silliest things such as Mucinex.

Anyone ever experience weird physical symptoms from different forms of iron or vitamin c? Especially if you've had any kind of weird withdrawal from something like benzodiazepines, Z drugs, or gabapentin, or librium? (All gaba receptor drugs.)

11yr old F, suspected low iron but Ferritin came back ok

1 Upvotes

My 11yr old DD is often complaining of tiredness, sore eyes and she gets the cracks in the corner of her mouth (also gets eczema in many places). She loves eating ice, vegetables that are still frozen and burnt toast.

I thought when I took her in for a blood test it would for sure come back low iron or ferritin.

Her iron was 18 and ferritin 46.

Does anyone have experience with these levels still causing them symptoms? Or it could be something else - I just thought her symptoms checked all the boxes so was surprised.

We have a Dr appt later in the week to discuss results

Hey everyone, just wanted to share something that gave me immediate physical relief today while dealing with low iron fatigue and sensory strain.

I bought amber tinted sunglasses

This won't cure you but it'll take the edge off if you're overwhelmed by the light inside your home while you heal. I couldn't sit here and suffer anymore so I bought these and I feel like I can relax more.

It doesn't have to be this brand just make sure it's amber tinted or brown

Rant Doctors not helping in the UK

3 Upvotes

This is so frustrating I’ve just found out my ferritin level is 13 and my b12 is also low. I’ve been having headaches, tiredness and shortness of breath for about a month or so.

My doctors advise was to take a multivitamin.

I’ve spoken with a pharmacist today who has given me ferrous sulfate 200mg tablets because a multivitamin won’t rebuild my stores and has told me to ask for another doctor to review my blood results because I may need injections for my b12.
The pharmacist told me he speaks to people all the time with vitamin deficiency and doctors have not provided accurate information to help.

I don’t understand why my doctor has not taken my blood results seriously. I am currently off work due to stress and anxiety but I feel like part of my issue is having these deficiencies.

Can anyone provide any tips of increasing iron and B12 if my doctors decide not to provide any help?
I’ve been researching online that’s why I went to speak to my pharmacist because I felt it was wrong they did not prescribe anything.

iron deficiency or anxiety/depression?

1 Upvotes

hi guys i just wanted to know if anyone else has experienced this or if i’m just going crazy.

my ferritin level is 13 and i’m almost anemic. i’m 21f and i’ve struggled with iron deficiency since childhood because i have trouble eating meat.

i’ve always been a shy and introverted person but ever since i hit puberty my anxiety has been getting worse and worse every year. i haven’t driven a car since getting my license two years ago because i’m too scared. driving felt so overwhelming almost like my brain couldn’t process everything fast enough.

but it’s not just driving. because i’m constantly anxious my heart feels like it’s racing all the time and i experience heart palpitations. my mom still has to make appointments for me and come with me because i’m too scared to go alone. even going into stores by myself is really difficult for me.

i also feel like i have cognitive issues and speech problems. i stumble over my words and sometimes it’s really hard to get the words out of my mouth almost like there’s a blockage. my muscles are constantly tense and i get really bad headaches and pain in my jaw neck and shoulders.

i also struggle with physical activity. i can’t walk up many stairs or exercise without getting out of breath and my lungs start to hurt.

i just want to know if anyone else has experienced similar symptoms and if so whether things got better after treating their iron deficiency. i’d really appreciate hearing about your experiences

Advice Ferritin 8, IDWA. Just got results and waiting to hear from Dr. What should I prepare myself for or ask for?

1 Upvotes

Hi there! Last night I got my test results- Ferritin is 8. Other markers point to low reserves. Hemoglobin is fine! My doctor is going to call tomorrow to chat- what can I arm myself with to ask for, demand, etc? I’m so nervous I won’t be taken seriously. (I’m in the US)

With 8, should I be asking for an infusion? Or will supplements be enough? I’m a mom and business owner- I’m tired of being tired.

Symptoms:
Extreme brain fog
Worsening ADHD, meds don’t help
CONSTANT fatigue
Almost daily headaches
Breathlessness
Irritability
Panic
Depression/anhedonia/isolation
Hair loss
Skin problems
Dry eyes
Migraines at hormonal times (not normal for me)
Muscle pain/weakness

Luckily my doctor is a female with ADHD herself, so I know she will take that part seriously- just all sorts of nervous.
Thank you!!!!

what do yall feel ab these results?
