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.
A wide city, the 22, and work that is often on your feet
Garden Grove stretches from neighborhoods near the 22 to the edge of Little Saigon and the streets around Brookhurst and Westminster. Many patients stand for work, drive the 22, and take care of parents or kids in the same day. That is a lot of load before anyone mentions exercise. Low back pain and neck pain are often traffic-plus-work stories. Knee pain is often a standing-shift story. We would rather hear the shift length than a vague activity score.
Food is also part of the week in a way that matters for gut visits. If you are coming for gut health or food sensitivities, bring the real pattern of meals, not a cleaned-up version. A sensitivity panel is not an automatic first step.
Why the drive is long, and how to make it reasonable
The 22 east to the 55 south, then the 73 or local freeway connections toward Mission Viejo, is the common path. About 22 miles. Thirty-five minutes is a gift. Fifty is normal at the wrong time of day. The suite is 26400 La Alameda, Suite 100, Mission Viejo, CA 92691. Parking on site. Monday through Thursday, 9 to 6.
Because the trip is long, we try not to waste it. You should leave with a plan you can run at home so you are not commuting for a three-minute adjustment. Call (949) 312-1754 to pick a time that is not the peak of the 22. The free consultation is 20 minutes if you want to confirm the trip is worth a full evaluation.
What we can do on that visit
Hands-on options include mobilization, myofascial release, neurodynamics, and exercise. Sciatica is examined as nerve-root pain, not as any pain near the hip. Headaches are screened for urgent features first.
Systemic visits use advanced bloodwork or GI-MAP only when the question requires them. The Garden Grove chiropractor page lists the local links.
Cost of a longer drive
Travel time is the main cost on top of care. The fees are out of network, with superbills and HSA/FSA. We will tell you if a closer clinician is the smarter next step for what you described. We would rather say that on the phone than have you sit on the 22 for a problem we do not treat.
The chiropractors are Drs. Sani and Tara Kohen. See the about page and the office page.
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.
