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.
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.
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.
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.
