Leaky Gut Treatment in Tustin, CA

People say leaky gut when they mean the gut barrier might be letting more through than it should. The plainer name is intestinal permeability. Testing can explore that question. It cannot prove the barrier caused an autoimmune disease, and it is not the same workup as a breath test or a food panel. For patients coming from Tustin, the office is about 16 miles away, 25–40 minutes, by the 55 south to the 73 toward Mission Viejo.

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.

Old Town, the Legacy, and the North Tustin hills

Tustin has three different weeks. Old Town is walkable, with short blocks and a lot of sitting in cafes and small offices. Tustin Legacy, on the old base, is wide, new, and built around a car. North Tustin and the hills toward Foothill are grades, older homes, and a drive down to the 55. A low back from Legacy commuting is not a knee from a North Tustin hill. We ask which one you live in before we guess at a load.

The District and the shopping around the Legacy add standing errands on top of desk jobs. Neck pain and headaches often belong to the screen. Knee pain and hip pain show up when hill residents add steps without a plan. Plantar fasciitis shows up in people whose walking is almost all concrete between the car and a door.

South on the 55

The 55 south to the 73 is the usual path to La Alameda. About 16 miles. Twenty-five minutes is a good day. Forty is a 55 that is not cooperating. Address: 26400 La Alameda, Suite 100, Mission Viejo, CA 92691. Parking at the building. Monday through Thursday, 9 to 6.

Do not book the visit as a gap between school pickup in Old Town and a meeting. The exam needs you present, not halfway back on the freeway in your head. Call (949) 312-1754. A complimentary 20-minute consultation is available if you want to meet the doctors before an evaluation.

Chiropractic, rehab, and labs from Tustin

McKenzie Method work is a strong fit when back or neck pain has a direction that makes it better or worse. Corrective exercise is the homework. Adjustments are used when a specific joint is restricted, after the screen that says a thrust is appropriate.

Functional medicine visits cover thyroid, sleep, and gut health when those are the actual complaint. The Tustin chiropractor page collects the local routes into the three pillars.

Fees, referrals, and the doctors

Out of network. Superbill. HSA and FSA. No referral required. We will not change a prescription from your physician. Emergency symptoms, including sudden neurologic loss, go to the ER rather than to La Alameda.

Drs. Sani and Tara Kohen practice at FRI. Their backgrounds are on the about page. The suite and gym are on the office page.

Extra context on Leaky Gut

Describe symptoms without using the slogan first. Say whether you bloat, which foods seem to set you off, whether stool changed, and whether skin or joints flared in the same month. Add NSAID use, recent antibiotics, and alcohol pattern, because those details belong in a barrier conversation. If a physician already diagnosed celiac disease or inflammatory bowel disease, bring that record. FRI will not re-diagnose it and will not tell you to leave that specialist. The useful outcome of this visit is a clear decision: stool test, different test, or no test yet.

Tight junctions are a real piece of anatomy, and they are also easy to oversell. A marker on a stool report is a clue about the sample, not a photograph of your intestinal wall. You should hear that limit out loud. If food reactions are the louder problem, the plan shifts to that page. If fermentation is louder, the plan shifts to a breath test. Neuromuscular Rehabilitation does not repair a lining. It is there when pain changes how you move and eat while the gut question is being sorted with your physicians.

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.
