Bloating, stool changes, and food reactions
You might bloat by evening, swing between loose stool and constipation, or feel fine until a specific meal. Reflux, nausea, and a noisy abdomen belong in the same history. So does the week the pattern started, after travel, an antibiotic, or a stretch of high stress.
FRI treats that timeline as the map. Drs. Sani Kohen, D.C. and Tara Kohen, D.C. ask what you eat, how fast you eat it, and whether pain, not food, is what ruins your appetite. Functional Medicine does not start by forbidding half the grocery store.
Tests are chosen from the history
Not everyone needs every gut test. A person with gas an hour after fruit is a different case from someone with blood in the stool, and the second of those needs a physician promptly. The kit is picked to match the question, not to fill a panel.
GI-MAP stool testing looks at organisms and digestion markers in the stool. SIBO breath testing asks about fermentation in the small intestine. Food sensitivity testing is a separate question about immune reactivity, not a substitute for either of those.
Three neighbor problems, three different pages
Small intestinal bacterial overgrowth, intestinal permeability, and food reactivity get mixed together online. They are neighbors, not copies. The SIBO page is about breath testing and fermentation. The leaky gut page is about the barrier question. Food sensitivities covers IgG and IgA, which are not an allergy diagnosis.
You might need one of those conversations, or more than one, but only if the history points there. Ordering all three on the first day is not the default. A clear question beats a thick stack of paper you cannot use.
Digestion, energy, and the rest of care
Poor digestion can sit beside fatigue, skin changes, or joint stiffness. That overlap is a reason to look, not a reason to blame the gut for every symptom you have. Sleep, thyroid pace, and medications belong in the differential your physicians are already managing.
Functional medicine at FRI does not replace a primary physician, endocrinologist, gastroenterologist, or mental health clinician. Bleeding, black stool, unexplained weight loss, or trouble swallowing goes to a gastroenterologist. Nutrition and supplementation here follows the test you actually needed.
What to expect when you are seen for Gut Health
A complimentary 20-minute consultation is available if you want to describe the pattern before testing. FRI is out of network, provides superbills, and accepts HSA and FSA funds. Hours are Monday–Thursday, 9–6.
You will be asked about stool form, timing of bloating, antibiotics, and travel. One test may be enough to start. Results are read with symptoms, not as a list of foods banned for life.
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 Gut Health
Before the visit, note three days of meals and the hour bloating or urgency shows up. Mark antibiotics, antacids, and any recent stomach bug. Say whether symptoms cluster at breakfast, after fruit, or only when you are traveling. That level of detail decides which test is even worth opening. If you already had a colonoscopy or a celiac test, bring the result so FRI does not talk past it. The overview visit is allowed to end with no kit at all when the history points to meal timing, a medication, or a physician's workup still in progress.
People often want one root cause. Digestion is usually a set of questions. Organisms in a stool sample, fermentation on a breath test, and an IgG or IgA pattern are not interchangeable findings. Treating them as one word, gut, leads to a plan that does not fit. You should leave knowing which question was asked. Neuromuscular Rehabilitation is there if abdominal wall pain or a back problem is changing how you eat and train, but it is not a treatment for an infection. You should be able to name the question a kit is meant to answer.
Questions patients ask
Do I need GI-MAP, a breath test, and a food panel?
Usually no. Each test answers a different question, and FRI picks from your history rather than dumping a panel on everyone. Stool testing looks at what is in the colon sample. Breath testing looks at fermentation related to the small intestine. A food sensitivity panel is another decision. You should know why a kit was chosen.
When should I see a gastroenterologist first?
Blood in the stool, black stool, trouble swallowing, persistent vomiting, or unintentional weight loss needs a physician, often a gastroenterologist, before a functional kit. Functional medicine at FRI does not replace that clinician, your primary physician, an endocrinologist, or a mental health clinician. Come here for the pattern that remains after urgent problems are ruled out, or alongside that care.
Can gut symptoms affect energy?
They can travel with fatigue, brain fog, and joint stiffness. That does not mean the gut is the only cause. Thyroid, sleep, mood, and medications are still on the list. FRI will say so. If a stool or breath test is used, it is to answer a digestion question you can describe, not to explain your entire health in one report.
Will you put me on a strict diet immediately?
No. A long forbidden-food list on day one is not the plan. Food changes, if any, come after the history and after the test that matches it. They are individualized and revisited. There is no brand protocol and no supplement dose on this page. Chiropractic Sports Medicine is separate care if pain, not digestion, is the main limit.
