Ferritin 8, constant fatigue and brain fog led me to an iron infusion. Here’s my real recovery experience, symptoms, side effects and results.

If you’ve landed on this blog because you’re Googling things like “Do I need an iron infusion?”, “Ferritin 8 symptoms,” “Why am I exhausted all the time?” or “How long does an iron infusion take to work?” — trust me, I completely understand.

 

A few months ago, I was deep in the same internet spiral, trying to connect the dots between my constant fatigue, brain fog, low motivation, and the strange feeling that my body simply wasn’t functioning the way it used to. I kept convincing myself I was just stressed, overworked, or sleep-deprived. Like many women, I normalized feeling unwell because life keeps moving, responsibilities don’t pause, and exhaustion slowly becomes part of your personality.

What shocked me most was discovering how severe my iron deficiency actually was. My ferritin levels were critically low, my iron saturation was almost nonexistent, and suddenly all the symptoms I had been dismissing started making sense. Looking back, my body had been sending warning signs for months.

This blog is my honest and detailed iron infusion journey — from the symptoms I ignored and the blood test results that changed everything, to the anxiety before the infusion, the side effects I worried about, and what recovery genuinely felt like afterwards. If you’re nervous about getting an iron infusion, wondering whether low ferritin can really make you feel this awful, or simply searching for a real experience that feels human instead of clinical, I hope this helps.

The internet often makes recovery stories sound dramatic and instant. Mine wasn’t. I didn’t wake up glowing with limitless energy the next day. But I did slowly realize how much low iron had been affecting my daily life, my focus, my energy levels, and even my mental wellbeing. And honestly? That realization alone changed the way I look at women’s health forever.

One thing I wish someone had told me earlier is that iron deficiency can affect almost every aspect of your life. It doesn’t just make you feel tired. It can impact your ability to think clearly, exercise, stay motivated, manage stress, and even enjoy everyday activities. When your body lacks iron, it struggles to transport oxygen efficiently and maintain normal energy production. The result can be a collection of symptoms that seem unrelated at first but are actually connected by one underlying issue.

For me, the hardest part was not realizing how much I had adapted to feeling unwell. Because the symptoms developed gradually, I adjusted my expectations without noticing. I stopped expecting to feel energetic. I stopped expecting to wake up refreshed. I stopped expecting to have the same stamina I once had. Instead, I built my life around managing exhaustion. It wasn’t until I started treatment that I understood how abnormal my “normal” had become.

How I Found Out I Had Severe Iron Deficiency

For months, I felt exhausted in a way that didn’t feel normal anymore. Not just “I need another coffee” tired — but physically drained, mentally foggy, and emotionally depleted. I could sleep for hours and still wake up feeling heavy. Simple things like climbing stairs or getting through the day felt harder than they should have. I struggled with concentration, motivation, and energy levels, but because the symptoms developed gradually, I adapted to them without realizing how much worse I was actually feeling. That’s the dangerous thing about iron deficiency — it sneaks up on you slowly enough that exhaustion starts to feel like your default setting.

Initially, I blamed everything else. Stress. Motherhood. Hormones. Burnout. Lack of sleep. I even started wondering whether my partial thyroidectomy history could somehow be connected because once you start Googling symptoms at midnight, absolutely everything begins to sound possible. The surprising part was that I didn’t fit the typical narrative I associated with iron deficiency anemia. My periods weren’t unusually heavy, and I wasn’t expecting my iron studies to come back so abnormal. But when I finally did a full blood test, the results explained everything almost instantly.

The appointment itself was fairly routine. I described my symptoms to my doctor and expected to hear the usual advice about stress management, sleep, and self-care. Instead, blood work was ordered to investigate further. At the time, I almost felt guilty for pursuing testing because I had convinced myself I was probably overreacting. Looking back, I’m incredibly grateful that I listened to my instincts and followed through.

My Iron Deficiency Blood Test Results

These were my results before the iron infusion:

• Ferritin: 8
• Iron Saturation: 5%
• Iron: 19
• Haemoglobin: 11
• MCV: 70

My doctor explained that while my haemoglobin had not dropped dangerously low yet, my ferritin levels showed that my iron stores were severely depleted. In simple terms, my body had basically run out of backup reserves. That’s when the conversation about iron infusions began — and honestly, hearing the word “infusion” immediately made everything feel far more serious than I had expected.

I remember staring at the results and feeling both relieved and overwhelmed. Relieved because there was finally an explanation for how awful I felt. Overwhelmed because I realized this wasn’t something that would simply disappear with a few early nights and an extra cup of coffee. My body genuinely needed treatment.

Common Iron Deficiency Symptoms I Experienced

Looking back now, the signs of low iron and low ferritin were everywhere. At the time, though, I kept dismissing them because none of them felt dramatic enough individually. It was only when everything started adding up together that I realized how much iron deficiency had been affecting my body and daily life. I constantly felt physically tired no matter how much I rested. My brain felt slower, foggier, and less focused. Even basic tasks started feeling heavier mentally and physically, and I had this persistent sense that my energy levels were never fully recovering.

One of the most frustrating parts about iron deficiency symptoms is how easy they are to dismiss as “normal adult life.” Women especially are conditioned to push through exhaustion. We continue working, parenting, socializing, and functioning while quietly running on empty underneath it all. That’s why so many people don’t realize low ferritin can affect you long before severe anemia develops. You can technically still be functioning while your body is internally struggling to maintain basic energy production.

I also noticed that my patience was shorter than usual. Small tasks felt overwhelming. My productivity dropped significantly, and I often found myself staring at a screen unable to focus. At the time, I assumed I was simply burned out. Now I understand that my body was lacking the resources it needed to function properly.

Symptoms of low ferritin and iron deficiency:

• Extreme fatigue
• Brain fog
• Weakness
• Low energy levels
• Difficulty concentrating
• Feeling physically drained
• Breathlessness
• Poor stamina
• Lack of motivation
• Tiredness even after sleeping

The biggest surprise for me was learning that you can absolutely have significant iron deficiency symptoms even if your haemoglobin isn’t critically low yet. Low ferritin alone can make you feel awful. And because my periods were not excessively heavy, I never initially considered iron deficiency as the main explanation. That’s why I always tell people now: if you constantly feel exhausted, get proper blood work done instead of assuming it’s “just stress.”

Another symptom I experienced was exercise intolerance. Activities that used to feel manageable suddenly felt exhausting. I found myself avoiding workouts because I simply didn’t have the energy. Even walking longer distances felt more difficult than it should have. At the time, I blamed a lack of fitness. In reality, my body was struggling because it lacked adequate iron stores.

Why I Needed an Iron Infusion Instead of Iron Tablets

When my doctor first suggested an iron infusion, my immediate reaction was panic. In my head, iron deficiency meant taking supplements, eating more spinach, and maybe drinking orange juice for vitamin C. An IV iron infusion sounded intense and honestly made me feel like my situation was suddenly far more serious than I had realized. But because my ferritin levels were so low and my iron stores were almost depleted, my doctor explained that oral iron tablets would likely take a very long time to replenish my levels properly. An iron infusion would work faster and restore my iron reserves more effectively.

Naturally, I handled this information in the calmest and most rational way possible: by Googling every single side effect, reading endless Reddit threads, comparing Ferinject and Monofer experiences, and mentally preparing for catastrophic reactions that never actually happened. Health anxiety truly deserves its own full-time job category. I spent days overanalyzing every possible risk, convincing myself I would somehow experience the rarest side effect in medical history. Meanwhile, the nurses at the clinic later treated the entire procedure like the most routine thing in the world.

We discussed different IV iron options including Ferinject and Monofer, and after several rounds of overthinking, I finally booked the appointment. Looking back now, the anticipation and anxiety beforehand were genuinely worse than the actual iron infusion itself. The procedure was far simpler, calmer, and less dramatic than my imagination had prepared me for.

My doctor also explained that iron tablets can sometimes cause digestive side effects such as constipation, nausea, and stomach discomfort. Even when tolerated well, they often take months to significantly improve iron stores. Given how depleted my ferritin levels were, an infusion offered a more efficient solution.

My Iron Infusion Experience

On the day of the infusion, I arrived feeling nervous but hopeful. The clinic environment was calm and professional, which immediately helped ease some of my anxiety. The nurses explained the process, answered my questions, and reassured me that iron infusions are performed regularly.

The infusion itself involved inserting a small IV cannula into my arm. Once everything was connected, the iron solution was administered slowly. I spent most of the time sitting comfortably, scrolling on my phone, reading, and occasionally checking in with the nursing staff.

To my surprise, the procedure was uneventful. I didn’t experience any dramatic reactions or immediate complications. The staff monitored me throughout the infusion and for a short period afterwards to ensure everything was fine.

The entire experience was far less intimidating than I had imagined. If you’re feeling anxious about an upcoming iron infusion, I completely understand. But based on my experience, the anticipation was significantly worse than the reality.

Iron Infusion Side Effects

One of my biggest concerns before treatment was the possibility of side effects. After spending far too much time reading online forums, I was convinced something would go wrong.

Fortunately, my side effects were relatively mild. I experienced some fatigue and mild aches in the days following the infusion. I also felt slightly off for a short period, but nothing severe enough to interfere with daily life.

Common side effects that people may experience after an iron infusion can include:

• Headache
• Fatigue
• Muscle aches
• Joint pain
• Nausea
• Dizziness
• Temporary changes in taste
• Mild flu-like symptoms

Everyone responds differently, and some people experience no side effects at all. Others may notice temporary discomfort as their body adjusts. It’s always important to discuss any concerns with your healthcare provider and follow their advice regarding recovery and monitoring.

Recovery After My Iron Infusion

One of the most common questions people ask is how long it takes to feel better after an iron infusion. Unfortunately, there isn’t a universal answer.

For me, the improvement was gradual rather than immediate. During the first few days, I didn’t notice any dramatic changes. In fact, I was hyper-focused on analyzing every sensation and wondering whether the infusion was working.

After a couple of weeks, I started noticing subtle improvements. My energy levels felt more stable. I wasn’t crashing as hard in the afternoons. My concentration improved, and the constant mental fog began to lift.

Over the following weeks, the changes became more noticeable. Tasks that previously felt exhausting became easier. I felt more capable of handling daily responsibilities without constantly feeling depleted. The difference wasn’t magical or overnight, but it was meaningful.

Perhaps the most significant change was realizing how much low iron had been affecting my quality of life. Once my body started recovering, I could finally compare how I felt before and after treatment. The contrast was eye-opening.

What I Learned From This Experience

If there’s one lesson I took away from this journey, it’s that women often normalize symptoms they shouldn’t. We become so accustomed to functioning while exhausted that we stop questioning whether something deeper might be going on.

I spent months assuming my symptoms were simply part of a busy life. I told myself everyone felt this tired. I convinced myself I just needed more sleep, better routines, or stronger coffee. In reality, my body was trying to tell me something important.

Iron deficiency is incredibly common, yet it can have a profound impact on physical health, mental clarity, and overall wellbeing. The symptoms can be subtle at first, making them easy to overlook. That’s why proper testing is so important.

If you’re experiencing persistent fatigue, brain fog, weakness, or unexplained exhaustion, don’t ignore it. Advocate for yourself. Ask questions. Request blood work if appropriate. You deserve answers.

Final Thoughts

My iron infusion journey wasn’t dramatic, but it was life-changing. It taught me to pay closer attention to my body, to take symptoms seriously, and to stop assuming that constant exhaustion is simply part of being an adult.

Finding out my ferritin was 8 explained so much of what I had been experiencing. The infusion itself was straightforward, the recovery was gradual, and the improvements were absolutely worth it. Most importantly, it reminded me that feeling exhausted all the time is not something we should automatically accept as normal.

If you’re currently researching iron deficiency, low ferritin, or iron infusions, I hope sharing my experience has helped ease some of your concerns. While everyone’s journey is different, you’re not alone in wondering what’s wrong, feeling anxious about treatment, or searching for reassurance.

Sometimes the answer really is hidden in a blood test. And sometimes, getting that answer can be the first step toward feeling like yourself again.

Not all fatigue is caused by low iron, but constant exhaustion should never be ignored. Alongside addressing underlying health issues, these tips on How to Boost Energy as a Mother can help you build healthier daily habits and improve your overall wellbeing.

Lots of Love,
