When “just tired” turns into a daily struggle
Fatigue is more than needing a nap. It can look like brain fog at work, low motivation to exercise, relying on caffeine to get through the afternoon, or feeling like your “battery” never fully charges. Medically, fatigue is a symptom—not a diagnosis—so the most helpful next step is identifying what’s driving it and building a plan that supports your whole system: sleep, hormones, nutrients, stress response, digestion, inflammation, and recovery.
At La Mer Holistic Medicine, we approach persistent fatigue the way it behaves in real life: multi-factorial. That means we blend integrative medical insight with mind-body support and individualized testing when appropriate—so you’re not left guessing.
Why fatigue happens (and why quick fixes usually fail)
Many people are told their labs are “normal” and sent home with generic advice. But fatigue can come from overlapping root causes—some obvious, some subtle. Conventional medicine is excellent at ruling out emergencies and major disease; functional and holistic care can be especially helpful when symptoms persist and your quality of life is shrinking.
Common contributors we consider
If fatigue doesn’t improve after several weeks, it’s worth a clinical evaluation to identify underlying causes and determine the right labs and next steps. (medlineplus.gov)
A functional medicine-style “map”: symptoms + patterns + targeted testing
The goal isn’t to run every test—it’s to match your story to smart, clinically relevant data. That includes your timeline (when fatigue began), triggers (illness, stress, hormonal shifts), and your specific pattern (sleepy vs. wired-and-tired vs. post-exertional “crash”).
When fatigue has a “crash after exertion” pattern
Some people notice that a workout, a busy workday, or even a social event wipes them out for days. That post-exertional worsening is discussed in ME/CFS guidance as a key symptom called post-exertional malaise (PEM). If this sounds familiar, pacing and gentle, individualized recovery strategies matter more than pushing harder. (cdc.gov)
Optional table: fatigue patterns and what they can suggest
| What you notice | Often worth exploring | First helpful steps |
|---|---|---|
| Energy dip after lunch; cravings; shaky if meals are delayed | Blood sugar variability, insulin resistance, meal composition | Protein-forward breakfast; balanced meals; reduce liquid sugar |
| Wired at night, tired in the morning | Stress load, sleep timing, stimulant habits | Consistent wake time; evening light reduction; nervous system downshifting |
| Low mood + low drive + “heavy body” fatigue | Mood/sleep interplay, inflammation, nutrient status | Sleep hygiene; daily outdoor light; check iron/B12/vitamin D when indicated |
| Hot flashes, night sweats, sleep disruption, mental fog | Perimenopause/menopause symptom support options | Discuss lifestyle + medical options; personalize based on history |
Note: This table is educational—not diagnostic. Persistent fatigue should be evaluated by a licensed clinician. (medlineplus.gov)
Hormones & fatigue: what to know (without hype)
Hormonal transitions can significantly affect energy—especially when sleep is disrupted. During perimenopause and menopause, symptoms like hot flashes and “mental fogginess” are common, and lack of sleep can amplify mood changes and fatigue. (support.endocrine.org)
Where Bioidentical hormone optimization may fit
If your symptoms and history point toward a hormone contribution, options may include lifestyle strategies, non-hormonal medications for certain symptoms, or carefully selected hormone therapy. Risks and benefits vary based on age, timing, health history, and the type of therapy used. If you have a uterus, estrogen is typically paired with a progestogen to protect the uterine lining. (mayoclinic.org)
If hormone support is part of your plan, our goal is the same as yours: improved energy, steadier mood, better sleep, and results that feel like “you,” not overcorrected.
A practical, step-by-step reset for low energy
1) Clarify what “fatigue” means for you
Is it sleepiness, low motivation, muscle heaviness, brain fog, or post-exertional crashes? Different patterns point to different next steps. Fatigue isn’t the same as drowsiness, and that distinction matters clinically. (medlineplus.gov)
2) Build “sleep protection,” not just sleep hygiene
Start with the one habit that creates the biggest ripple effect: a consistent wake time (even on weekends). Then add evening light reduction, a caffeine cutoff, and a 10-minute nervous-system downshift (breathing, gentle stretching, or Reiki-style relaxation).
3) Stabilize blood sugar with “3 anchors”
Protein at breakfast, fiber at lunch, and an earlier dinner help many people reduce energy crashes. This is especially relevant in high-demand professional schedules when meals get rushed.
4) Move in a way that restores (not depletes)
If you feel better after movement, build consistency with walking, mobility, and strength training at a sustainable dose. If you crash after exertion, focus on pacing and symptom-guided activity instead of “no pain, no gain.” (cdc.gov)
5) Consider targeted labs and “special testing” when it’s truly helpful
If fatigue persists despite foundational changes—or if you have red flags, new symptoms, or significant life disruption—testing can help clarify direction. This can include standard labs and, when appropriate, advanced evaluations to look deeper at contributing factors.

FAQ: Fatigue & integrative care
How long is “too long” to feel fatigued?
If fatigue doesn’t improve after a few weeks of reasonable rest and lifestyle support—or if it’s worsening—get evaluated. Persistent fatigue can signal medical, mental health, sleep, or medication-related contributors that are treatable. (medlineplus.gov)
What’s the difference between fatigue and sleepiness?
Sleepiness is the urge to fall asleep. Fatigue is more like low energy and reduced capacity, even if you’re not “nodding off.” They often overlap, but they can point to different causes. (medlineplus.gov)
Can hormones really cause fatigue?
Hormones can contribute—often through sleep disruption, mood changes, and metabolic shifts. Perimenopause and menopause can include symptoms like hot flashes, mood changes, and “mental fogginess,” which can cascade into daytime fatigue. (support.endocrine.org)
If my labs are “normal,” does that mean nothing is wrong?
Not necessarily. “Normal” ranges can be broad, and symptoms can come from multiple small imbalances rather than one dramatic abnormality. A functional approach looks at patterns, trends, and the full clinical picture—while still respecting medical safety and evidence.
When should I seek urgent care for fatigue?
Seek urgent evaluation for sudden severe fatigue with chest pain, shortness of breath, fainting, new neurological symptoms, black/bloody stools, or rapid unexplained weight loss. If you’re unsure, it’s safer to get checked promptly.
