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.
Hills, horses, and the 241
Yorba Linda is hills, larger lots, and a trail culture that includes horses as well as hikers. Black Gold and the canyon edges mean repeated time in a saddle or on a grade. The 241 is how a lot of the city reaches south county for work. Sitting the toll road and then riding, or the reverse, is a specific week. Hip and SI pain, low back pain, and neck pain all show up in that combination. A saddle and a car seat are not the same posture, and the exam should not pretend they are.
Brush-canyon fire season and hot training days also change hydration and headaches. Headaches still get a neurologic screen. We do not blame every headache on the Santa Ana winds. Knee pain on the descents gets a loading plan that includes the hill you live on.
Using the 241 instead of crossing the county sideways
The 241 south is the route that makes Yorba Linda to Mission Viejo rational. It is a toll road, about 28 miles, often 35 to 55 minutes depending on where in town you start and whether you hit the 91 first. Exit toward La Alameda and come to 26400 La Alameda, Suite 100, Mission Viejo, CA 92691. Monday through Thursday, 9 to 6. Parking at the building.
If you already take the 241 toward Irvine for work, a Mission Viejo appointment can sit on the south end of a day you were driving anyway. Say so when you book. Call (949) 312-1754. The 20-minute consultation is reasonable before you commit a toll-road morning to a full evaluation.
Rehab that respects the hill and the saddle
Gait and posture and corrective exercise are more useful than a generic core list. Joint mobilization is often kinder than a hard thrust when a hip or spine is already irritable from the week's riding. ART is there for specific soft-tissue restrictions, not as a standing massage appointment.
Hormone and sleep questions from this commute are real. Perimenopause and sleep pages describe the limits of what we take on. The Yorba Linda chiropractor page is the hub.
The non-negotiables
Out of network, superbill, HSA/FSA. No referral. We do not replace your physician, your vet is not our department, and we do not give riding clearance against another clinician's restriction. Bring that restriction with you.
Drs. Sani and Tara Kohen practice at the Mission Viejo suite. The about page and office page introduce them and the building.
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.
