You wake up tired. You push through your day on caffeine and grit. You cancel plans, forget things, and wonder if you’re burning out—or worse, broken.

“If you’ve ever been told your fatigue is just stress, age, or hormones—this post is your roadmap to real answers.”

At PureHealth Primary Care, we believe your body whispers before it screams. And when you feel tired all the time, it’s not just about sleep—it’s about systems.

Fatigue is One of the Most Ignored Medical Symptoms

It’s one of the top reasons for primary care visits across Canada. It disrupts work, relationships, and mental health—but often gets written off as “normal.”

• You wake up exhausted, even after 8 hours of sleep.
• Your brain feels foggy by mid-afternoon.
• You’ve been told “your labs look normal,” but you don’t feel normal.
• Your life is on pause, and no one’s giving you the full picture.

This post will show you what to check, what to ask for, and how to get your energy back—without being dismissed.

Top 7 Root Causes of Chronic Fatigue (And What Tests Actually Matter)

Fatigue isn’t a diagnosis—it’s a signal. Here are the most common, correctable causes we see every week at PureHealth, backed by clinical evidence:

1. Iron Deficiency
   Ferritin below 30 μg/L is not optimal, even if hemoglobin is normal. If your periods are heavy or you follow a plant-based diet, ask for a ferritin test.
2. Vitamin B12 Deficiency
   B12 below 250 pmol/L may cause fatigue, tingling, low mood, or brain fog. Early deficiency is often missed.
3. Thyroid Dysfunction
   TSH above 4.0 with low Free T4 = hypothyroidism. Symptoms may include hair thinning, constipation, cold sensitivity, and low drive.
4. Blood Sugar Imbalance
   An HbA1c of 6.0–6.4% means prediabetes. Fatigue + crashes after meals? Ask for a fasting glucose or continuous glucose monitoring.
5. Sleep Apnea
   Especially if you snore, wake up with a dry mouth or headache, or urinate at night. You can feel exhausted and never suspect this is the cause.
6. Chronic Inflammation
   CRP or ESR blood markers can uncover post-viral syndromes, long COVID, or autoimmune fatigue.
7. Hidden Mental Load
   PTSD. Anxiety. Depression. Burnout. These aren’t just mental—they’re physical drains. If you’re always “on,” your nervous system never recovers.

What Labs Should You Ask For?

A truly fatigue-focused workup should include:

• CBC: To rule out anemia and infection
• Ferritin + Iron Panel
• Vitamin B12 and Folate
• TSH and Free T4
• HbA1c or Fasting Glucose
• CRP and/or ESR
• Liver Enzymes + Creatinine

“Your labs are normal” means nothing unless you ask: “What was tested? What were the actual numbers?”

Fatigue Symptom Tracker

If you’re unsure whether your fatigue is “normal,” try this self-check. If you answer YES to 3 or more, it’s time for a medical workup.

1. I sleep 7+ hours, but still wake up tired.
2. I need caffeine just to function during the day.
3. My brain feels foggy or slow—especially by afternoon.
4. Rest doesn’t feel restorative.
5. I’ve noticed changes in mood, weight, or motivation.
6. I’ve had these symptoms for more than 2 weeks.
7. I feel like no one’s taking it seriously.

How to Talk to Your Provider Without Being Dismissed

Fatigue is often brushed off unless you speak its language. Here’s how to make sure your voice is heard:

• Say this: “This fatigue is affecting my quality of life.”
• Bring this: A list of your symptoms and when they started.
• Ask this: “Can we check my thyroid, iron, and B12 just to be thorough?”
• Clarify this: “Can I get a copy of my lab results for my records?”
• Remember this: It’s okay to seek a second opinion.

“You don’t have to be aggressive to be assertive. Your job is not to convince them you’re sick. Your job is to advocate for answers.”

6 Steps to Start Your Recovery Today

You don’t need a diagnosis to start healing. These science-backed habits can support your energy, mood, and cellular function while we work toward answers:

1. Start with sleep hygiene: Lights off by 10:30 PM. No screens 1 hour before bed. Try magnesium glycinate, breathing exercises, or guided sleep meditations.
2. Eat for energy: Whole foods. Iron-rich proteins. B-vitamins. Omega-3s. Avoid sugar crashes. Fuel your cells, not just your cravings.
3. Move daily—gently: Walking, yoga, or even 10 minutes of stretching improves circulation and nervous system tone.
4. Track your inputs: Notice what drains vs. restores you. Certain environments, people, or tasks may be depleting you more than you realize.
5. Test and treat what matters: Book with a provider who will explore the root cause—iron, thyroid, hormones, B12, inflammation, insulin resistance.
6. Redefine rest: It’s not just sleep. It’s nervous system down-regulation. That might mean less hustle, more stillness. Permission granted.

You’re Not Lazy. You’re Not Weak. You’re Not Alone.

“Fatigue is not just about energy. It’s about chemistry. About nervous system bandwidth. About biology and burnout. And it’s fixable.”

At PureHealth Primary Care, we don’t gaslight fatigue. We investigate it. We take you seriously. And we work with you to build back what’s missing—mentally, physically, emotionally, and cellularly.

Your life isn’t supposed to feel like survival. Let’s change that together.
