A Female Officer’s Fatigue Was Iron Deficiency, Not Stress

The following account was shared with us by an anonymous patrol officer in Michigan. We hear versions of this story constantly from women in public safety. We’re publishing it because it deserves to be said out loud.

I’m 33, six years on patrol, and for about two of those years I felt like I was moving through wet cement.

It wasn’t dramatic. I just couldn’t do the things I used to do. I’d finish a foot pursuit — maybe forty yards — and my heart would be slamming for ten minutes afterward. I stopped lifting because I’d get lightheaded standing up from a bench. My hands were always cold in the car, even in June. I was chewing ice constantly. My partner started buying the crushed-ice bags at the gas station for me as a joke.

My cycles had been getting heavier for years. Seven, eight days. I’d plan my shifts around it. I mentioned it at my annual, along with the exhaustion, and my doctor ran a CBC. Hemoglobin came back at 12.1. She looked at the screen and said, “Your blood count is normal. Honestly, with your job, this is probably just stress. Have you thought about cutting back on caffeine?”

That was it. Two years of feeling like I was eighty years old, and the answer was less coffee.

I finally paid out of pocket for my own panel after a friend in the fire service told me to ask for ferritin specifically. Mine was 7. Seven. The nurse who called me said she was surprised I was upright, let alone chasing people.

What Actually Happened Clinically

Her hemoglobin was normal, so the workup stopped. That’s the entire failure in one sentence.

Hemoglobin is the last thing to drop. Your body burns through stored iron first — the iron sitting in your liver, spleen, and bone marrow — and only when those stores are gone does it start shorting red blood cell production. Ferritin measures the stores. Hemoglobin measures the end product. By the time hemoglobin falls out of range, you’ve been running on empty for a long time.

This is called iron deficiency without anemia, and it’s increasingly recognized as its own clinical problem, not a “pre-anemia” curiosity. It causes fatigue, exercise intolerance, poor concentration, cold intolerance, hair shedding, restless legs, and — yes — pagophagia, the compulsive ice chewing that is one of the most specific and most-ignored signs in medicine.

The physical findings in her story track exactly: a heart rate that won’t settle after brief exertion (less oxygen-carrying reserve), cold hands, and a strength ceiling that keeps dropping.

There’s also the lab-range trap. Many labs flag ferritin as abnormal only below 10–15 ng/mL, a threshold built around preventing anemia, not around feeling and performing normally. Recent work using physiologically based thresholds — the point at which the body actually starts showing signs of iron-restricted red cell production — puts the cutoff meaningfully higher, in the mid-20s for premenopausal women. Plenty of clinicians use 30 ng/mL as a floor and prefer symptomatic athletes and heavy-exertion workers to sit well above it. A ferritin of 7 isn’t borderline anything. It’s a diagnosis.

Why This Keeps Happening to Women in Public Safety

Three things stack up.

Heavy menstrual bleeding is underestimated by everyone, including the person having it. Most women have no reference point for what’s normal. If your cycles have always been heavy, they feel normal to you, so you don’t report them as a problem — you report the fatigue. And “heavy periods” rarely gets translated into “chronic iron loss” in a seven-minute visit.

Occupational health for women in fire and law enforcement is still an afterthought. Department physicals were designed around a male-dominated workforce and the cardiac risk that kills that workforce. Ferritin isn’t on the standard panel. Nobody asks about cycle length at a fit-for-duty exam.

Fatigue in a first responder is the easiest symptom in the world to explain away. You work rotating shifts. You see terrible things. You don’t sleep. Any provider can attribute exhaustion to the job and be plausibly right — which means real, treatable, measurable causes go unexamined for years. Shift work and iron deficiency are not mutually exclusive. She had both.

What a Better Workup Looks Like

If you’re a woman in public safety and you’re tired in a way that sleep doesn’t fix, this is the conversation to have.

Labs to ask for by name:

1. Ferritin — the single most important one. Ask for the number, not “normal.” Write it down.
2. CBC with differential, including MCV and RDW. A rising RDW with a normal hemoglobin is an early tell.
3. Iron, TIBC, and transferrin saturation — TSAT under about 20% supports the diagnosis.
4. CRP — ferritin is an acute-phase reactant and rises with inflammation, so a “normal” ferritin alongside a high CRP can be falsely reassuring.
5. TSH, free T4, and free T3 — thyroid disease and iron deficiency mimic each other and often travel together.
6. Vitamin B12 and folate, and vitamin D, especially if you’re indoors or on nights.

Questions worth asking directly:

• “My hemoglobin is normal — can we check my iron stores specifically?”
• “What was my actual ferritin number?”
• “Given how much I’m losing each cycle, is there a gynecologic cause we should evaluate?” (Fibroids, adenomyosis, and IUD-related bleeding are common and treatable.)
• “If oral iron wrecks my stomach, what are my options?” Every-other-day dosing with vitamin C on an empty stomach absorbs better than daily dosing for many people — hepcidin blunts absorption for roughly a day after a dose. IV iron is a real option for people who can’t tolerate or can’t absorb oral.

Set expectations on the timeline. Hemoglobin can normalize in weeks, but rebuilding stores takes three to six months of consistent repletion. Recheck ferritin at the three-month mark. And if you’re not looking for the source of the loss, you’re just refilling a leaking tank.

The Bottom Line

You know your own baseline better than any panel does. If you used to be able to do something and now you can’t, that’s data — and “your blood count is normal” is not an answer to it. One inexpensive lab, ordered by name, closed a two-year gap in this officer’s care.

Women are a growing share of the fire service and law enforcement, and the occupational health infrastructure hasn’t caught up. Until it does, you’ll have to ask for the test yourself. Ask for it.
