Fatigue Treatment
You're not lazy. You're not just getting older. Fatigue that doesn't resolve with sleep has a cause, and it's testable. We run a full panel of hormones, thyroid, iron, vitamin D, B12, cortisol, metabolic markers, and inflammatory markers to find what's draining your energy.
Why You're Still Tired After 8 Hours of Sleep
Chronic fatigue is one of the most common reasons people walk into Med Matrix. They've been tired for months, sometimes years. They sleep a full night and wake up feeling like they didn't. Coffee stops working. Exercise makes it worse. Their primary care doctor ran a basic panel, said everything looks normal, and offered an antidepressant or told them to sleep more.
That basic panel usually includes a CBC, metabolic panel, and maybe TSH. That's it. It misses the things that actually cause persistent exhaustion: suboptimal thyroid function (free T3, free T4, reverse T3, thyroid antibodies), hormone imbalances (low testosterone in men, progesterone drops in women), cortisol dysfunction from chronic stress, iron and ferritin depletion, vitamin D insufficiency, B12 deficiency, blood sugar instability, and chronic inflammation.
We test all of it. Over 80 biomarkers in a single draw. Because fatigue isn't a diagnosis. It's a symptom of something measurable that your other doctor didn't look for.

Patient Story
“There were things on there that I hadn't known. For example, Hashimoto's disease. I had asked my physician to test me for that and they didn't. And that did come up on there.”

Patient Story
“These glands have a complex relationship with each other. In conventional medicine there's this idea that the thyroid is off on an island, the adrenal glands are off by themselves, and the ovaries are separate. All of these hormones are in the blood together.”

“I was so anxious that I was really looking at getting on an anxiety medication, and then I know now that that was a function of my hormones. I don't feel like that anymore. I feel great.”

What We Actually Find
In our experience treating over 3,000 patients, fatigue almost always traces back to one or more of these root causes:
- Thyroid dysfunction. Not just hypothyroidism. Subclinical patterns where TSH looks "normal" but free T3 is low, reverse T3 is high, or antibodies are elevated. This is the most commonly missed cause of fatigue in women.
- Hormone imbalance. Low testosterone causes fatigue in both men and women. Progesterone drops, estrogen dominance, and cortisol burnout all tank energy.
- Nutrient depletion. Iron, ferritin, B12, vitamin D, magnesium. These are cheap to test and easy to fix, but they have to be found first.
- Gut dysfunction. Poor absorption, bacterial imbalance, chronic low-grade inflammation starting in the gut. If your body can't absorb nutrients from food, supplements alone won't fix the fatigue.
- Chronic stress response. HPA axis dysfunction (often called "adrenal fatigue"). Your cortisol rhythm is off, you can't wake up properly, and you crash mid-afternoon.
Once we identify the cause, the treatment plan is specific to you. Hormone optimization, targeted supplementation, gut repair protocols, lifestyle interventions. Not guesswork. Not a one-size-fits-all vitamin pack.
What Causes Chronic Fatigue That Won't Go Away?
Fatigue that persists for weeks or months is your body signaling that something measurable is wrong. It's not laziness, and it's not "just stress." The causes fall into a few categories that standard blood work almost never tests for.
Thyroid dysfunction beyond TSH. Your primary care doctor probably checked TSH and called your thyroid normal. But TSH is a signaling hormone from the brain. It doesn't tell you what's happening at the tissue level. Free T3 (the active hormone), reverse T3 (which blocks thyroid receptors), and thyroid antibodies (which indicate autoimmune attack) all need to be tested. A patient can have a "normal" TSH while their free T3 is tanked and reverse T3 is through the roof. That's a fatigue pattern we see multiple times a week in our South Portland clinic.
HPA axis dysfunction. Chronic stress rewires your cortisol rhythm. Instead of peaking in the morning (when you need to wake up) and dropping at night (when you need to sleep), cortisol flatlines or inverts. The result: you drag yourself out of bed, crash at 2pm, then feel wired at midnight. This is testable through cortisol pattern analysis, and it responds to targeted treatment. Learn more about the thyroid and adrenal connection.
Hidden nutrient gaps. Iron and ferritin are the most commonly missed. A ferritin of 15 is technically "in range" but far below the 50-80 range where most people feel energized. Vitamin D below 40, B12 under 500, and depleted magnesium all contribute to persistent tiredness. These are inexpensive to test and straightforward to correct once identified.
Gut-driven inflammation. Your gut produces most of your body's serotonin and plays a direct role in nutrient absorption. Bacterial imbalance, intestinal permeability, or chronic low-grade infection in the gut creates systemic inflammation that drains energy. Patients often describe this as feeling "heavy" or "inflamed" alongside their fatigue. If your body can't properly absorb the nutrients you eat, no amount of supplements will fix the problem until the gut is addressed.
What Does a Chronic Fatigue Treatment Plan Look Like?
Every patient's fatigue has a different driver, so every treatment plan looks different. That said, there's a consistent process we follow.
It starts with testing. We draw 80+ biomarkers in a single blood panel: full thyroid panel, sex hormones, cortisol, metabolic markers, inflammatory markers, and nutrient levels. We also run an InBody 770 body composition scan. Most patients tell us it's the most thorough health assessment they've ever had.
Your provider (typically Dr. Sasha Rose or Dr. Paul Laband for fatigue cases) reviews everything before your 60-minute consultation. No rushing. No five-minute appointment. They walk through every result, explain what's off, and build a protocol targeting your specific root causes.
Common interventions include:
- Thyroid medication adjustment or optimization (T4/T3 combination when conversion is poor)
- Hormone restoration for testosterone, progesterone, or DHEA when labs confirm deficiency
- Targeted nutrient repletion (iron, B12, vitamin D, magnesium) at therapeutic doses
- Cortisol rhythm restoration through adaptogen protocols and lifestyle changes
- Gut repair when absorption or inflammation is identified as a factor
Most patients notice a shift within 2 to 4 weeks. Some, particularly those with complex multi-system fatigue, need 6 to 12 weeks to fully resolve. We monitor labs and adjust the plan as your body responds. The goal isn't just "less tired." It's sustained, consistent energy from morning through evening.
Common Symptoms We See
- Waking up exhausted after a full night of sleep
- Afternoon energy crash between 2pm and 4pm
- Relying on caffeine just to function
- Brain fog, poor concentration, or forgetfulness
- Exercise making you more tired instead of energized
- Feeling physically heavy or inflamed
- Irritability or mood changes tied to energy dips
- Low motivation or losing interest in activities you used to enjoy
- Getting sick more often than usual
- Unexplained weight gain alongside fatigue
What We Test for This Condition
Free T3
The active thyroid hormone that drives cellular energy production. Low free T3 is the most common missed cause of fatigue.
Reverse T3
Blocks thyroid receptors even when other thyroid numbers look normal. Elevated in chronic stress and inflammation.
TPO Antibodies
Detects autoimmune thyroid attack (Hashimoto's) that can cause fatigue years before TSH goes out of range.
Ferritin
Iron storage marker. Can be technically 'in range' at 15 while optimal is 50 to 80. Low ferritin is one of the easiest fatigue fixes.
Vitamin D (25-OH)
Below 40 ng/mL is associated with fatigue, poor immune function, and mood changes. Most people in Maine are deficient.
B12
Essential for nerve function and red blood cell production. Deficiency causes fatigue, brain fog, and numbness.
Cortisol
Your primary stress hormone. Dysregulated cortisol patterns cause morning exhaustion and afternoon crashes.
Fasting Insulin
Identifies insulin resistance and blood sugar instability, a hidden driver of energy crashes and metabolic fatigue.
hs-CRP
Measures systemic inflammation. Chronic low-grade inflammation drains energy and impairs recovery.
Testosterone (Total + Free)
Low testosterone causes fatigue in both men and women. Often dismissed in women and undertested in men under 50.

Real Patient Stories
Hear from patients who came to Med Matrix with this condition.
Jonathan
Jonathan, a nurse with over 10 years of experience, came to Med Matrix despite healthy lifestyle habits (non-drinker, non-smoker) because he was waking up tired, crashing by mid-afternoon, and relying on caffeine to get through shifts. Originally interested in peptides, he found TRT made the biggest difference. After roughly 10 to 15 weeks on TRT and supplements, he gained nearly 6 pounds of muscle, dropped about 2.5% body fat, improved his focus at work, and stopped relying on caffeine.
“Normal labs does not mean well.”
Peggi
Peggi came to Med Matrix knowing she was not operating at her best, with low energy and poor sleep, and wanted real answers instead of guesswork. The in-depth lab work and one-hour review gave her clarity and validation about what was actually happening in her body. After targeted changes, her energy and sleep improved significantly and she feels more balanced overall.
“What stood out to me the most was how personal the experience was, from the discovery call all the way to the in-depth lab and the one-hour review which explained everything that was going on. I wasn't making it up in my mind. I finally understood what was going on.”
