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.
Santa Margarita Parkway to La Alameda
Santa Margarita Parkway into Mission Viejo, or Antonio Parkway to local streets, covers the trip. About 7 miles and 12 to 20 minutes when the parkway is moving. School traffic changes that. The suite is 26400 La Alameda, Suite 100, Mission Viejo, CA 92691. Park at the building. Monday through Thursday, 9 to 6.
You are close enough to do a real course of care without giving up half a day. Use that. Spacing visits so you can practice the home plan is more valuable than stacking them. Call (949) 312-1754 or begin with the free 20-minute consultation.
Hands-on care and the lab side
Functional movement screening and gait analysis fit a town that hikes and then sits. ART is the soft-tissue option for overuse from sport, not a spa massage. Neurodynamics belongs when leg or arm pain behaves like a nerve.
For non-joint problems, sleep, hormonal imbalance, and gut health each have a page. The city starting point is the Rancho Santa Margarita chiropractor page.
Policies that do not change because you are close
Out of network. Superbill. HSA and FSA accepted. No referral required. We coordinate with physicians and we do not edit their prescriptions. Emergency spine and neurologic symptoms go to the ER.
Drs. Sani and Tara Kohen practice together at FRI. Read the about page and the office page if you want the people and the building before you drive Santa Margarita Parkway.
Dove Canyon, O'Neill trails, and a planned-town schedule
Rancho Santa Margarita spreads into Dove Canyon, Robinson Ranch, Tijeras Creek, and the central town. O'Neill Regional Park and the surrounding trails add climbing that a map of the shopping district does not show. Golf and youth sports fill weekends. Weekdays are often a drive out Antonio or Santa Margarita toward a desk somewhere else. Knees and hips meet the trails. Necks and low backs meet the car. We ask which village you live in because the grade and the drive are not the same in Dove Canyon as they are next to the lake in town.
Lower back pain after the drive out of the hills, and knee pain after O'Neill, are typical reasons to come to La Alameda. Scoliosis questions come from parents who want movement help without a promise that exercise will straighten a structural curve. We will not make that promise.
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.
