Why your bloodwork says “normal” but you feel anything but

The cellular-energy piece: why standard bloods can read normal while you feel depleted.

You did the sensible thing. You went to the doctor, said you were exhausted, and they ran your bloods. The results came back normal. And somehow that made it worse — because now you're just as tired, with a piece of paper implying it's all in your head.

It isn't. The test isn't lying — but it's answering a much narrower question than the one you're asking.

"Normal" means "not diseased" — not "well"

Standard reference ranges are built to catch disease. They flag you when a number falls below a floor set for outright illness — not the level at which a woman actually feels well. Between those two points sits an enormous grey zone: technically in range, nowhere near thriving. That grey zone is where a huge number of exhausted women quietly live.

The number that usually gets missed

When a GP checks your iron, the headline number is haemoglobin — the iron circulating in your blood right now, carrying oxygen. Your body defends that number fiercely. To keep it looking respectable, it quietly drains your stored iron — ferritin — first. Ferritin can empty for months or years before haemoglobin ever drops. Yet most standard panels don't measure it unless someone asks, and when they do, a level barely above the disease floor still gets stamped "normal." Many practitioners consider a ferritin around 50 the realistic floor for steady energy, clear thinking and stable mood — and plenty of women don't feel themselves until they're comfortably above it.

What to ask for at your next appointment

Don't ask "is my iron normal?" Ask "what is my ferritin — the actual number?" Ask for a copy of your results. Numbers put the information back in your hands, and they let you watch the trend over time, which tells you far more than any single reading.

Feeling is data too

The most useful assessment isn't only on paper. How you wake, how you climb stairs, how your cycle behaves, whether your words come when you call for them — that's data. If your bloods say fine and your body says otherwise, the answer isn't to dismiss your body. It's to ask better questions of the bloods.

If this sounds like you, take the quiz on the homepage — Are you depleted? — or bring your results along and begin with a consultation; I'll read them with you.
