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.
South on the 5 or the 73 from Irvine
From central and north Irvine, I-5 south toward Mission Viejo is the simple drive. From the south villages and from many business parks, the 133 to the 73 toll road is often cleaner. About 12 miles. Twenty minutes is realistic off peak. Thirty-five is realistic when the 5 is slow through Lake Forest. The office is 26400 La Alameda, Suite 100, Mission Viejo, CA 92691. Building parking. Monday through Thursday, 9 to 6.
Irvine patients are used to efficient clinics. This one is deliberately less efficient. An exam takes time. If you need to be back on Jamboree for a meeting, book a morning visit and leave a buffer. Phone (949) 312-1754. The 20-minute consultation is the right first step if you are shopping for a style of care rather than ready for testing.
Desk symptoms and training symptoms, handled separately
Corrective exercise and DNS are how we retrain sitting and breathing patterns after the exam shows they matter. Chiropractic adjustments are used when a joint is not moving, not as a subscription. Carpal tunnel symptoms get a neck screen and a nerve exam, because a keyboard is not automatically the wrist.
The same city asks functional medicine questions: thyroid, burnout-style fatigue people want explained, and gut symptoms after years of desk lunches. Those are history-first visits. The hub page is the Irvine chiropractor page.
Insurance and coordination
Many Irvine employers offer HSA or FSA accounts. Those cards work here. We are still out of network and we still give a superbill rather than billing your plan directly. Lab work is quoted before it is ordered. We will not tell you to stop a medication from your Irvine physician.
Drs. Sani and Tara Kohen lead the clinic. Training details are on the about page. If you want to see the rehab gym before you drive the 5, use the office page.
Business parks, village trails, and a city built for sitting
Irvine's villages do not share a body. Woodbridge and University Park are older loops and pools. Turtle Rock and Quail Hill have more grade. The Spectrum and the Great Park are newer and more spread out. The job, for a lot of patients, is a campus along Jamboree, Barranca, or the Irvine Business Complex: long meetings, a badge, and a walk that is only from the garage. Neck, upper back, and headache complaints often start there. Knee and hip complaints often start on the village trails people use to undo the job.
We do not treat Irvine as a single activity level. A cyclist on the San Diego Creek trail and a software lead who has not exercised since a move from Woodbridge need different exams. Neck pain and headaches are common desk presentations. Hip and SI pain shows up when someone adds mileage fast. Say which village and which campus.
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.
