Tired All the Time? It’s Not Just Your Age
If you’ve ever been told:
“Well, you’re just getting older…”
…but you’re in your 30s or 40s and feel like you're dragging yourself through the day, this post is for you.
Because chronic exhaustion isn’t normal.
And it’s definitely not something you should just accept.
So let’s talk about what’s actually behind that “always tired” feeling, and why age has less to do with it than you think.
Fatigue Is a Signal — Not a Personality Flaw
When patients come to me saying they’re tired all the time, I don’t just blame age or say “try sleeping more.”
We investigate.
Here’s what I see most often underneath that fatigue:
5 Common Root Causes of Fatigue
1. Nutrient Depletion
Low ferritin, low B12, low magnesium, low Vitamin D = low energy output.
Modern life depletes us. So does stress. So does under-eating.
If your cells don’t have the raw materials, they can’t make energy. It’s not your mindset, it’s your mitochondria.
2. Thyroid Sluggishness
You can have “normal” TSH and still be functionally hypothyroid.
Low Free T3 or high Reverse T3 = brain fog, fatigue, cold hands, slow metabolism.
(And spoiler: most docs only check TSH, not enough.)
3. Blood Sugar Crashes
If you’re doing coffee-only mornings, skipping meals, or snacking on carbs without protein…
…you’re riding the blood sugar rollercoaster.
That crash at 11am or 3pm? It’s not just life, it’s your glucose tanking.
4. Cortisol Imbalance
Too much stress for too long = a flattened cortisol rhythm.
You wake up groggy, feel “okay-ish” mid-day, then get a second wind at 10pm.
That’s not a personal flaw. It’s a nervous system pattern, and it’s fixable.
5. Postpartum or Hormone Shifts
If you’ve had a baby, lost your period, hit perimenopause, or stopped birth control, you’re likely feeling the hormone whiplash.
Low estrogen, low testosterone, or low progesterone all impact energy, mood, and recovery.
The Real Problem? You’ve Been Dismissed
You were probably told:
“Your labs are normal”
“Try melatonin”
“It’s just stress”
“Maybe it’s anxiety?”
No one asked about your ferritin.
No one checked your cortisol rhythm.
No one asked why you were tired.
The Fix: Rebuild, Don’t Just Push Through
You don’t need more caffeine.
You need fuel.
You need regulation.
You need root-cause labs and the right support.
Because being tired all the time isn’t normal.
It’s a sign your body needs help.
