CONDITION
Chronic Fatigue & Low Energy
When it isn't just 'stress' — the hormonal, thyroid, metabolic, and mitochondrial causes we actually test for.
The short answer
Symptoms that go beyond 'tired'
- Waking unrefreshed even after 8+ hours of sleep
- Afternoon energy crash requiring caffeine or a nap
- Brain fog, poor focus, word-finding difficulty
- Loss of motivation for exercise, hobbies, or work
- Poor exercise recovery — soreness that lasts days
- Cold hands and feet, hair thinning, dry skin
- Low libido, mood changes, irritability
The most common root causes
Suboptimal sex hormones
Low testosterone in men, and declining estrogen/progesterone/testosterone in perimenopausal women, disrupts sleep, mood, and cellular energy production simultaneously. Often the first system to check.
Thyroid dysfunction
Even mildly elevated TSH or low free T3 causes profound fatigue. Standard workups often miss it because only TSH is ordered. A full thyroid panel is essential.
Insulin resistance & metabolic dysfunction
Blood sugar swings drive energy crashes. Elevated fasting insulin can appear years before HbA1c moves — and is a fixable cause of chronic fatigue.
Cortisol dysregulation
Chronic stress flattens the natural cortisol curve, producing 'tired but wired' — hard to fall asleep, hard to wake up, no midday energy.
Nutrient deficiency
Low ferritin (iron stores), B12, vitamin D, and magnesium are common, cheap to test, and dramatically fatiguing when depleted.
Chronic low-grade inflammation
Elevated hs-CRP or homocysteine signals inflammation that suppresses mitochondrial energy production. Often addressable with lifestyle and targeted therapy.
How we work it up
Our comprehensive panel goes well beyond a standard physical. We assess total and free testosterone, estradiol, progesterone (women), SHBG, full thyroid (TSH, free T3, free T4, reverse T3, TPO/TG antibodies), fasting insulin, HbA1c, lipids, hs-CRP, homocysteine, ferritin, B12, vitamin D, and a comprehensive metabolic panel. Results are reviewed against optimal ranges — not just 'normal.'
Treatment options
- Hormone optimization (TRT for men, bioidentical HRT for women)
- Thyroid support when indicated
- GLP-1 or metabolic support for insulin resistance
- Peptide therapy (BPC-157, thymosin, growth-hormone-releasing peptides)
- NAD+ IV therapy for mitochondrial support
- Targeted micronutrient IVs (Myers' cocktail, B-complex, magnesium)
- Sleep, stress, and training protocol coaching
Frequently asked questions
What's the difference between 'being tired' and chronic fatigue?+
Ordinary tiredness resolves with sleep, rest, and a lighter week. Chronic fatigue persists for months, isn't relieved by rest, and interferes with work, exercise, and relationships. When fatigue lasts more than 6 months without a clear cause, it deserves a real medical workup — not another cup of coffee.
Can low testosterone cause fatigue?+
Absolutely. Low testosterone in men — and increasingly in perimenopausal women — is one of the most under-diagnosed drivers of chronic fatigue. It affects sleep quality, mood, motivation, and recovery from exercise all at once.
Could my thyroid be causing this?+
Yes. Subclinical hypothyroidism (TSH in the 'normal' range but with symptoms) is extremely common and often missed when providers only order TSH. A full panel — TSH, free T3, free T4, reverse T3, thyroid antibodies — gives a much clearer picture.
What is 'adrenal fatigue' and is it real?+
The term 'adrenal fatigue' isn't a recognized medical diagnosis, but dysregulated cortisol rhythms — from chronic stress, poor sleep, and overtraining — are real and measurable. We assess cortisol pattern alongside thyroid, sex hormones, and metabolic function rather than treating a buzzword.
Do IV therapy or peptides help with fatigue?+
They can, when the underlying cause is identified. NAD+ therapy, targeted peptides, and vitamin/mineral IV protocols address mitochondrial function, cellular repair, and nutrient status — but they work best on top of correcting the root hormonal or metabolic driver.
