Exhaustion that outlasts a hard week
You may sleep and still wake unrefreshed, cancel plans by noon, or feel flu-like after a walk that used to be easy. Brain fog often rides along. That experience is real. It is also not, by itself, a diagnosis this office will rename on the first visit.
Drs. Sani Kohen, D.C. and Tara Kohen, D.C. ask how long it has lasted, what makes it worse, and what physicians have already ruled out. Functional Medicine here does not claim to treat myalgic encephalomyelitis or chronic fatigue syndrome as a specialty protocol.
Thyroid, iron, and metabolic markers come first
A slow thyroid, low iron, and unstable glucose can each produce a tiredness that feels total. Those are common, testable questions, and they belong early. Advanced bloodwork can include iron studies and metabolic markers your physician may already be watching.
The thyroid dysfunction page explains why TSH alone can miss the question. A fuller panel is considered when temperature, bowels, and hair changed along with energy. Medication, if you take it, stays with the prescriber. FRI does not raise a dose from fatigue alone.
Sleep and gut are next, not a grab bag
Sleep and insomnia covers pain, caffeine, and a cortisol curve when nights are the obvious hole in the story. If you snore, gasp, or wake with headaches, a physician should evaluate sleep apnea. This office is not a sleep laboratory.
Gut symptoms earn a stool or breath test only when you have them. An organic acids test is sometimes used as a urine look at metabolic clues. It is not ordered because you are tired. It is ordered when the history makes that specific question worth the sample.
Mold or metals only if the history fits
A water-damaged building, a job with solvent or metal exposure, or a diet very high in certain fish can justify those workups. They are not the default explanation for fatigue. FRI will not tell you that all exhaustion is mold, and it will not open with a chelation plan.
Functional medicine at FRI does not replace a primary physician, endocrinologist, gastroenterologist, or mental health clinician. If mood, grief, or a medication is part of the exhaustion, keep those clinicians involved. Nutrition and supplementation follows the labs, without a brand protocol.
What to expect when you are seen for Chronic Fatigue
A complimentary 20-minute consultation is the place to see whether this workup fits. FRI is out of network. Superbills are available, and HSA or FSA funds are accepted. Hours are Monday–Thursday, 9–6.
Bring prior bloodwork, a medication list, and a short note on what a typical crashed day looks like. Testing starts with the most plausible drivers. You will not be enrolled in an ME/CFS protocol. Describe whether a short walk, a flight of stairs, or a full workday is what flattens you, because that scale changes which test is worth doing first.
Getting to Mission Viejo without donating the day
From central Anaheim and the resort area, I-5 south toward Mission Viejo is the direct freeway. From Anaheim Hills, the 55 south is often cleaner than fighting across to the 5. About 26 miles. Thirty-five minutes is off-peak. Fifty-five is rush hour, especially if you start on the 91. The office is 26400 La Alameda, Suite 100, Mission Viejo, CA 92691. Monday through Thursday, 9 to 6. Building parking.
Book the first appointment you can stand if you are coming from the Hills in the morning or returning north in the afternoon. Call (949) 312-1754. A 20-minute consultation can be scheduled before you invest in a full evaluation and a long freeway day.
Care after a long freeway
We build home programs specifically because you should not need to live on I-5. Corrective exercise, McKenzie self-treatment, and a small number of hands-on visits beat a permanent weekly commute for a crack. Sciatica care includes nerve testing and clear red flags. Bowel or bladder change with leg pain is an emergency, not a drive to south county.
Metabolic syndrome and weight questions are handled with labs and food, without a promised number of pounds, and beside your physician. The Anaheim chiropractor page is the index.
Practical policies
Out of network, superbill, HSA/FSA. No referral. We do not manage work injuries as a legal case. We will examine the injury. Bring any restrictions your employer or physician already wrote down.
Drs. Sani and Tara Kohen's training is on the about page. The clinic is on the office page.
The resort district, the Colony, and Anaheim Hills
Anaheim contains a resort economy and a hill suburb that do not share a skeleton. The resort district and the streets around it mean hospitality shifts, standing, and odd hours. The Colony and central Anaheim mean older neighborhoods and short local trips piled onto I-5. Anaheim Hills means grades, trails, and the 91 or the 55. Low back and neck pain from resort shifts are a standing-and-sleep story. Knee pain from the Hills is a descent story. Tell us which Anaheim.
Shift work also wrecks sleep, and sleep wrecks pain tolerance. If you work nights near the resort and you are also asking about sleep or headaches, bring the schedule. We will not hand you a sunrise routine you cannot use.
Extra context on Chronic Fatigue
Write a week of energy in plain numbers you understand: the hour you got up, the hour you had to stop, and what you did just before a crash. Note fevers, sore throats, and how long recovery takes after a short walk. Bring ferritin and thyroid labs if you have them so the first visit does not repeat a draw from last month. List every medication, including blood pressure pills and antihistamines, because several common drugs feel like fatigue. If a building smells musty, mention it, and also mention if it does not. Absence of an exposure is useful information.
The aim is a short list of tests that could change a decision, not a binder. You should know which question each tube or kit is asking. If results are ordinary, that is still a result, and the next step is not an automatic toxin story. Keep your primary physician in the loop. Functional Medicine can sit beside that care. It does not replace it, and it will not tell you the exhaustion has one hidden cause waiting in a single narrow panel. Ordinary explanations stay on the list until they are ruled out.
Questions patients ask
Do you treat ME/CFS with a set protocol?
No. FRI does not claim a specialty protocol for myalgic encephalomyelitis or chronic fatigue syndrome. Persistent exhaustion is taken seriously, and the visit looks for contributors such as thyroid pace, iron, glucose, sleep, and, when the history fits, gut or exposure questions. Your physicians remain in charge of any formal diagnosis and of medications.
Which labs come before a toxin test?
Thyroid testing and advanced bloodwork for iron and metabolic markers usually come before mold or metal testing. Those common drivers can look exactly like a mysterious fatigue. Exposure testing is added when a building, a job, or a diet makes it plausible. Ordering a scare panel first is not the approach.
What if I crash after exercise?
Say so. Post-exertional worsening changes how training is discussed, and it is a reason not to push a generic fitness plan. Neuromuscular Rehabilitation and Chiropractic Sports Medicine can still help pain, with load kept inside what you can repay. FRI will not promise that a supplement prevents a crash.
Can sleep apnea be sorted here?
No. If apnea is suspected, a physician should evaluate it. FRI is not a sleep-medicine lab. The office can look at pain that wakes you, caffeine, thyroid pace, and a cortisol curve on a DUTCH test when those questions fit. Those findings do not replace a sleep study your physician orders.
