Fatigue and brain fog when the blood work comes back normal

You wake up tired no matter how much you sleep, the words won't come, and every blood test is normal. They keep saying it's anxiety.

What people say about fatigue and brain fog

"Waking up tired no matter how much you sleep"

"I feel awful all the time. Physically, mentally."

"They just keep saying it's anxiety because the blood tests aren't identifying anything."

Why it is often missed. Blood work looks for disease. When it finds none, tiredness and brain fog are often put down to anxiety, and how hard your nervous system is working is never checked.

Why the upper neck may be involved. When the nervous system is stuck on, the body braces for an emergency that never ends. Digestion, healing, sleep and clear thinking get pushed aside, and fatigue and fog are often what's left. The brainstem, surrounded by the top bone of the neck, is part of the system that decides which mode you're in.

what the research looked at

One published study on fatigue and brain fog

Published 2012. The strongest design among them: cohort, pilot or before-and-after study. Each one is summarized in plain words in our research library: who was studied, what was measured, what was found, and where it falls short.

  • 2012 · Prospective studyNineteen people with chronic fatigue syndrome, six months after a NUCCA correction

One small study with no control group and one practitioner, from a journal PubMed does not index. Quality of life and sleep scores improved; that is not the same as showing the fatigue itself changed, or that it would for you. Persistent fatigue deserves a full medical workup as well.

1 study, published 2012. Strongest design: cohort, pilot or before-and-after study. 1 in the NUCCA lineage, ringed.

how we measure

The Lazar Method™ measures first

Everyone else told you what might work. We measure before anything is decided. Muscle tone shows how much energy your posture is costing you, and heart rate variability shows how much reserve your nervous system has.

Before any correction we measure how your nervous system is regulating your body: heart rate variability, thermal and muscle tone scans, PostureIQ™, and digital X-ray of the upper neck. Dr. Jonathan Lazar, D.C., or someone personally trained by him, will go over your scans and images with you. QSM3, the method used at our office, is a progression of NUCCA, and the correction is gentle and specific: no cracking, no twisting.

If we can help, we'll tell you. If we can't, we'll help you find someone who can.

  3. Clarify

  5. Restore

Please note: Ongoing fatigue deserves a full medical workup, including thyroid, iron and blood sugar.

Sample heart rate variability chart: autonomic activity against balance
A sample heart rate variability chart: how the nervous system balances fight or flight with rest and digest.
Heart rate variability, in plain words. The small, healthy change in time between heartbeats. It reflects how your nervous system balances fight or flight with rest and digest, and low variability can mean there is little reserve. It is a measurement, not a diagnosis, and not a condition in itself. What the research on heart rate variability looked at.

traveling for care

Coming from another state, or hours away?

People drive from across Michigan because nothing closer worked. If you live hours away, or in another state, working out the days, the hotel and the records shouldn't be yours to carry alone. Our office is at 203 S. Zeeb Rd, Ann Arbor, Michigan.

Why am I so tired when my blood tests are normal?

Blood tests look for disease, such as anemia or a thyroid problem, and they should be done. When they come back normal, a different question is often missed: how hard your nervous system is working. A system stuck in fight or flight uses energy all day, and that can be measured.

Can a chiropractor help with brain fog?

It depends on what is driving the fog, and no one can tell that from a symptom list. Published upper cervical research is thin: one small NUCCA study of chronic fatigue, and nothing on brain fog itself. What we can do is measure how your nervous system is regulating your body. If we can't help, we'll tell you.

What do you measure for fatigue?

Heart rate variability shows how much reserve your nervous system has and whether it is stuck in fight or flight. Muscle tone scans show how much energy your posture is costing you, and where. Together they turn tired all the time into numbers you can see, and compare on later re-scans.

Is it worth traveling for an assessment?

Only if your case makes sense for it, and we work that out before you book anything. Our team hears your story on a 15-minute Clarity Call, and for an intensive we read your records first. If you can't travel at all, Dr. Lazar works with a small number of remote patients.
