What Is Functional Medicine for Fatigue?
If you’ve been feeling tired all thetime—dragging yourself through the day, relying on caffeine to function, andcrashing before dinner—only to be told your labs are “normal,” you’re notalone.
Fatigue is one of the most commonsymptoms people report, yet it's often dismissed in conventional care. Many patients are left without answers, feeling like their exhaustion is just something they have to live with.
But at Caring for the Body, PLLC, we view fatigue differently.
In functional medicine, fatigue is not adiagnosis—it’s a clue. A message from your body that something deeper is out ofbalance.
Rather than masking your symptoms with aquick fix, Dr. Cynthia Libert takesthe time to ask why. Why is your bodystruggling to generate energy? What systems are overloaded, undernourished, orout of sync? And what can we do to restore optimal function so you can feeltruly well again?
If you’re ready for a compassionate,root-cause approach that looks at the wholeyou—body, mind, and spirit—you’re in the right place. Healing is possible,and we’re here to help you get your energy and your life back.
What Is Functional Medicine?
Functional medicine is a modern,science-based approach to healthcare that focuses on identifying and addressingthe root causes of illness—not justmanaging symptoms. It’s deeply personalized, systems-oriented, and designed totreat the whole person, not just adiagnosis.
Instead of asking, “What drug matchesthis disease?” functional medicine asks, “Whyis this symptom happening?” and “How can we help the body heal?”
Through in-depth testing, carefullistening, and ongoing partnership, Dr. Cynthia Libert helps patients uncoverhow inflammation, nutrient deficiencies, toxins, infections, sleep disruptions,or stress may be silently draining their energy.
Functional medicine is not an alternative to conventional medicine—it’san evolution of it. It works beautifully alongside traditional care and canoften help reduce reliance on medications by restoring balance naturally.
Why Functional Medicine Works forFatigue
If you’ve ever left a doctor’s officewith a prescription for an antidepressant or a sleep aid—but still no clearanswer for your fatigue—you’ve experienced the limits of symptom-basedmedicine.
Conventional care often aims to managefatigue by masking the symptoms. But in functional medicine, we ask deeperquestions:
What’sdisrupting your body’s energy production?
Which systems are under strain—and why?
We take a comprehensive, systems-basedapproach to assess and restore energy by evaluating key areas such as:
Mitochondrial Function
Yourmitochondria are your body’s cellular “power plants.” When they’re inflamed orundernourished, energy crashes—and so do you.
Thyroidand Adrenal Balance
Fatigue isoften linked to underactive thyroid function or cortisol imbalances caused bychronic stress.
Nutrient Absorption
Even a healthydiet won’t help if your gut isn’t absorbing key nutrients like B12, iron,magnesium, or CoQ10—all essential for energy production.
Sleep Quality and Circadian Rhythm
Functionalmedicine explores sleep architecture,not just hours of sleep—looking at melatonin, cortisol patterns, anddisruptions that rob you of true rest.
Stress,Trauma, and Mindset
Unresolvedtrauma, burnout, or negative thought patterns can contribute to deep,persistent fatigue—especially when the nervous system is in survival mode.
Root Causes of Fatigue WeInvestigate
Thyroid Dysfunction
Even“borderline” or subclinical hypothyroidism can cause profound fatigue,especially if thyroid hormone conversion or receptor sensitivity is impaired.
Adrenal Fatigue / Cortisol Imbalance
Chronic stresscan dysregulate your cortisol rhythm, leading to crashes, wired-but-tiredenergy, and burnout.
Chronic Infections
Underlyinginfections like Epstein-Barr virus (EBV),Lyme disease, or mold/mycotoxin exposure can keep yourimmune system stuck in overdrive and drain your energy reserves.
Gut Issues & Nutrient Malabsorption
Your gut iscentral to energy production. Inflammation, SIBO, leaky gut, or microbiomeimbalances can block the absorption of energy-boosting nutrients like iron,B12, magnesium, and CoQ10.
Hormone Imbalance
Low estrogen,progesterone, testosterone, or DHEA (especially during perimenopause orandropause) can contribute to physical and mental fatigue.
Mitochondrial Dysfunction
When yourmitochondria—your body’s cellular powerhouses—are damaged by toxins,infections, or oxidative stress, energy production slows to a crawl.
Sleep Apnea or Poor Sleep Hygiene
Even if youthink you're getting enough sleep, hidden sleep disruptions may be robbing yourbody of true rest and repair.
Food Sensitivities & Blood Sugar Instability
Unstable bloodsugar levels, gluten sensitivity, or inflammation triggered by food can lead toenergy crashes and brain fog.
Toxic Burden & Liver Stress
Exposure toenvironmental toxins (like pesticides, plastics, or heavy metals) can burdenyour detox pathways and lead to chronic fatigue.
Trauma,Grief, or Burnout
Emotionalwounds, spiritual exhaustion, and unresolved stress can deeply impact yournervous system, immunity, and energy levels.
