Intestinal permeability, in plain language
The lining of the intestine has a job: let nutrients across, and keep larger fragments and microbes on the inside of the tube. When that sorting gets sloppy, people call it leaky gut. FRI treats intestinal permeability as a question, not as a slogan that explains every symptom you have ever had.
You might notice bloating, food reactions that seem new, skin flares, or joint stiffness in the same season. Those clues can justify a look. They do not prove a porous gut, and they do not prove the gut created an autoimmune disease. Many autoimmune conditions have nothing to do with this mechanism.
Tight junctions are the seals between cells
Cells lining the intestine sit side by side. Tight junctions are the protein seals between them. When the seals are snug, traffic is selective. When they loosen, more material may cross. That is the idea behind the phrase you may already be using. It is a description of a barrier, not a diagnosis FRI stamps on day one.
Illness, some medications, heavy alcohol, and poorly digested food are among the stories people bring. Dr. Tara Kohen, D.C. and Dr. Sani Kohen, D.C. want that history before a kit. Functional Medicine does not open with a supplement stack aimed at junctions.
What a GI-MAP can and cannot prove
GI-MAP stool testing can describe organisms in the stool, signs of inflammation, and clues about digestion. Some reports include markers people associate with the barrier. None of that proves the lining is open, and none of it proves permeability caused your diagnosis.
A breath test asks a SIBO question. A food panel asks a sensitivity question. The gut health page explains why those are ordered separately. This visit stays on the barrier question. Food sensitivities are discussed only when reactions, not a theory, are in your history.
A different question from SIBO or a food list
Bloating an hour after carbohydrates points toward fermentation and belongs on the SIBO page. A single food that swells your lips is an allergy question for a physician. A vague sense that many foods now bother you might lead here, or it might lead to a simpler meal-timing problem. The history chooses.
Functional medicine at FRI does not replace a primary physician, endocrinologist, gastroenterologist, or mental health clinician. Nutrition and supplementation follows what the stool test and your symptoms support. There is no brand protocol, and sealing the gut is not described as the source of autoimmunity.
What to expect when you are seen for Leaky Gut
Book a complimentary 20-minute consultation if you want the barrier question sorted from the others. FRI is out of network. Superbills and HSA or FSA payment are available. Hours run Monday–Thursday, 9–6.
Expect a history of infections, medications, and which symptoms you think are gut-related. A stool test is not automatic. You will not be told that every autoimmune disease starts in the intestine.
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.
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.
Questions patients ask
Is leaky gut a diagnosis FRI makes?
People use that phrase, and FRI translates it into a question about intestinal permeability. A visit does not stamp leaky gut as a formal diagnosis that explains your whole chart. GI-MAP stool testing can add organism and inflammation clues. It cannot prove the barrier is open, and it cannot prove the gut caused an autoimmune disease.
Can a leaky gut cause every autoimmune disease?
No. FRI does not claim intestinal permeability causes every autoimmune disease, or even most of them. Some people with autoimmunity have gut symptoms worth testing. Many do not. If you have a diagnosed autoimmune condition, your rheumatologist or other specialist remains in charge. Gut testing is optional context, not proof of a single root cause.
How is this different from SIBO?
SIBO is about microbes fermenting in the small intestine, usually explored with a breath test. Permeability is about the barrier between the tube and the bloodstream, explored in part with stool clues that still cannot prove the lining is open. You can have one question without the other. FRI will not merge them into a single protocol.
Will one test give me a permanent food list?
No. A food sensitivity panel, if it is used at all, is not a lifelong ban list. It is discussed on its own page. Here the focus is the barrier question and what stool testing can actually show. Nutrition changes are individualized and revisited. Chiropractic Sports Medicine is unrelated to sealing a gut lining.
