What Your Chronic Fatigue Is Really Telling You

If it feels like you’re dragging yourself through the day—no matter how early you go to bed or how many cups of coffee you drink—you’re not imagining it, and you’re definitely not alone.

Chronic fatigue is something I hear about a lot from the clients I work with, and it's more than just being tired. It can feel like your body is running on empty, your brain is stuck in fog, and no matter what you try—nothing seems to work.

It’s frustrating. It’s isolating. And maybe worst of all, it often gets dismissed.

You’ve probably heard:
“Just get more sleep.”
“Try cutting out sugar.”
“Maybe it’s just stress.”

And while yes, sleep and nutrition and stress management all matter… the reality is that persistent fatigue is often your body’s way of waving a red flag. It’s trying to get your attention.

In functional medicine, we see fatigue not as the problem—but as the symptom of a deeper imbalance. Your energy isn't just about sleep or willpower—it’s connected to your hormones, gut health, nutrient stores, mitochondrial function, and how well your body is able to adapt to stress.

Let’s break down what might really be going on—and how we can begin to restore your energy from the inside out.

Chronic Fatigue Isn’t Just About Feeling Tired

Fatigue shows up differently for everyone. Sometimes it’s that classic bone-deep exhaustion that no nap can fix. But often, it’s more subtle.

Here are some signs you might be dealing with chronic fatigue or an energy imbalance—even if you’re technically “sleeping enough”:

• You struggle to get out of bed, even after 8+ hours of sleep

• You crash hard in the afternoon or get a second wind at night and can’t fall asleep

• You feel mentally foggy or have trouble focusing

• You get easily overwhelmed or feel emotionally flat

• You rely on caffeine or sugar just to function

• You don’t feel motivated, even when you want to be

If any of these sound familiar, I want you to know: this isn’t laziness, and you’re not broken.

These symptoms are your body’s way of saying: Hey, something’s off. And when we listen, we can begin to shift things—gently and intentionally—back toward balance.

What Causes Fatigue? Let’s Talk Root Causes

The truth is, fatigue doesn’t have a one-size-fits-all solution because it doesn’t have a one-size-fits-all cause. In functional medicine, we don’t just ask, “How can we fix this?”—we ask, “Why is this happening in the first place?”

Here are some of the most common root causes we uncover when someone is dealing with persistent fatigue:

1. Hormonal Imbalances

Hormones are your body’s internal messengers, and they play a huge role in your energy.

• Cortisol, your primary stress hormone, can be too high or too low (or both at the wrong times).

• Thyroid hormones regulate your metabolism—if they’re sluggish, you feel sluggish.

• Estrogen, progesterone, and testosterone imbalances can all contribute to poor sleep, low motivation, or that “wired but tired” feeling.

Here’s the kicker: many people are told their hormone labs are “normal,” even when they clearly don’t feel normal. That’s why we look beyond standard lab ranges to see what’s really going on functionally.

2. Nutrient Deficiencies

Even if you eat a balanced diet, your body may not be absorbing what it needs—or chronic stress may be depleting your stores faster than you can replace them.

We often see low levels of:

• B vitamins, especially B12 (critical for energy and focus)

• Magnesium (supports over 300 biochemical processes, including sleep and stress response)

• Iron and ferritin (not just for anemia—low iron can zap energy, especially in women)

• Vitamin D (key for immune and mood regulation)

Functional testing helps us identify these subtle depletions early, before they turn into bigger issues.

3. Gut Health Imbalances

Your gut is where you digest, absorb, and eliminate. If it’s not functioning well, your entire body pays the price.

Chronic constipation, bloating, reflux, or IBS-like symptoms are often signs of:

• Dysbiosis (imbalanced gut bacteria)

• Candida overgrowth

• Leaky gut (intestinal permeability)

• Poor absorption of key nutrients

Gut health is also directly tied to inflammation, which is one of the biggest energy drains there is.

4. Poor Sleep Quality

You might be in bed for 8 hours, but if you’re tossing and turning, waking up frequently, or waking up feeling more tired—you’re not truly getting restorative sleep.

Root causes of poor sleep include:

• Blood sugar instability overnight

• Elevated evening cortisol

• Histamine sensitivity (yes, this can spike at night!)

• Nutrient deficiencies (like magnesium or glycine)

Sleep is when your body heals and resets—so we always look at what’s disrupting that process.

5. Mitochondrial Dysfunction

Your mitochondria are the powerhouses of your cells—they produce the energy your body needs to function. When they’re sluggish or damaged (from toxins, chronic stress, or inflammation), your energy suffers at a cellular level.

We support mitochondria with targeted nutrients like CoQ10, acetyl-L-carnitine, and alpha-lipoic acid, as well as strategies to reduce oxidative stress.

How We Approach Fatigue in Functional Medicine

There’s no one magic pill—but there is a process.

We start by getting curious. What’s your story? What patterns have been missed? What testing could help us understand your symptoms more deeply?

Then, we build a personalized plan focused on:

• Functional labs to evaluate hormone balance, gut health, mitochondrial function, and nutrient status

• Food-as-medicine to stabilize blood sugar, reduce inflammation, and nourish your body

• Targeted supplementation to replenish what’s been depleted

• Lifestyle adjustments to support sleep, reduce stress, and regulate circadian rhythms

• Detox support to ease the burden on your liver, lymph, and mitochondria

Our goal is never just to “get you through the day”—it’s to restore the energy and vitality you deserve.

Quick Tips to Start Rebuilding Energy Today

While we always individualize care, there are a few foundational shifts that nearly everyone can benefit from:

✅ Prioritize protein and healthy fat at breakfast – This helps stabilize blood sugar and keeps energy steady throughout the day.

✅ Get sunlight within 30 minutes of waking – Natural light helps reset your circadian clock and boosts cortisol at the right time.

✅ Cut caffeine after noon – It can disrupt your body’s natural rhythm and delay melatonin release.

✅ Hydrate! Aim for half your body weight in ounces of water daily (add a pinch of sea salt if needed).

✅ Create a wind-down ritual – Think: herbal tea, blue light blockers, a warm bath, or gentle stretching. Your body needs cues to shift into rest mode.

Foods + Teas to Promote Restorative Sleep

What you eat in the second half of your day can set the stage for deeper, more restorative sleep. A few of my favorite evening options:

Sleep-Supportive Foods:

• Tart cherries – naturally high in melatonin

• Pumpkin seeds – full of magnesium and tryptophan

• Banana with almond butter – calming combo of magnesium, potassium, and fat

• Wild-caught salmon – omega-3s + vitamin D = sleep win

• Cooked leafy greens – gentle source of calming minerals

Herbal Teas:

• Chamomile – classic nervine for stress and tension

• Lemon balm – eases anxious thoughts

• Passionflower – improves sleep quality

• Tulsi (holy basil) – balances stress hormones

• Lavender & spearmint – soothing and fragrant, perfect for unwinding

You don’t have to do all of these. Start small. Add one calming tea or nutrient-dense evening snack. The body responds to consistency over perfection.

Fatigue Isn’t Your Fault—But It Is a Signal

If you’ve been feeling chronically exhausted, burned out, or just “off,” I want you to know this:

You don’t have to accept fatigue as your new normal.

You deserve to feel vibrant, focused, and alive in your body again—and that begins with identifying what’s really going on beneath the surface.

Functional medicine gives us the tools and framework to do just that. It’s not about slapping a label on your symptoms or giving you a temporary energy boost—it’s about supporting your body’s natural healing processes so energy becomes sustainable.
