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.
Finding the suite if you already live in town
26400 La Alameda is on the La Alameda corridor in Mission Viejo, Suite 100. If you are coming from the lake, it is a short cross-town drive, not a freeway project. Parking is at the building. Hours are Monday through Thursday, 9 to 6. People who work in Irvine or Santa Ana and live here often want the first appointment or the last. Say which commute you are protecting. Call (949) 312-1754.
The complimentary 20-minute consultation is available even if you can see the building from your errands. It is a conversation about fit. It is not a treatment and it is not a membership pitch. If you already know you want an evaluation, book that instead so we have time to test movement rather than only talk about it.
Using all three pillars without leaving the city
Chiropractic Sports Medicine in this office means assessment plus the tool that fits: adjustment, joint mobilization, Active Release, McKenzie Method, or tape and cups when they serve the plan. Neuromuscular Rehabilitation means DNS, neurodynamics, and corrective exercise after the exam, not a random circuit.
Functional Medicine is for the problems that do not yield to a joint exam alone: thyroid questions, gut symptoms, perimenopause, sleep, and energy. Labs such as DUTCH and GI-MAP are selected from the history. The Mission Viejo chiropractor page is the local hub, and the office page shows the rooms.
What neighbors should know before the first visit
You do not need a referral. Bring prior records if they exist. Red-flag spine symptoms, including new bowel or bladder changes, saddle numbness, or a leg that is rapidly getting weaker, belong in emergency care. We will help you sort ordinary back pain. We will not keep you in the suite if the story is an emergency.
FRI is out of network. Mission Viejo patients use HSA and FSA cards and superbills like everyone else. Drs. Sani and Tara Kohen are both chiropractors. Their training, including Dr. Sani's sports and functional medicine background and Dr. Tara's rehabilitation and imaging background, is on the about page.
Lake loops, youth sports, and the Oso corridor
Mission Viejo's body load is local. The Lake Mission Viejo path is flat and popular, which makes it a useful test: pain that shows up on that loop is not a hill problem. Marguerite Parkway and Olympiad Road are where a lot of the driving and the school traffic actually happen. Saddleback College and the commercial strips along Crown Valley add standing and sitting in the same afternoon. Florence Joyner Olympiad and the sports parks mean a city full of youth sports parents who also sit for work. We ask which of those you did this week.
Because you live here, follow-up is easy to schedule and easy to waste. A plan that depends on you coming in forever is a weak plan. We would rather teach you the movement or the drill that belongs to your actual week, whether that is a lake walk, a desk on La Paz, or a weekend tournament at one of the parks. Lower back pain and neck pain are the complaints we hear most from this pattern.
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.
