SIBO Breath Testing in Garden Grove, CA

You give a baseline breath sample, drink a measured amount of lactulose or glucose, and then collect breath at timed intervals. Microbes that ferment the substrate produce hydrogen or methane. Those gases enter the blood and leave in the breath, where the kit measures them. The pattern of the rise, and when it happens, is the result. A single number without a timeline is not the test.

SIBO breath testing takes a few hours of your morning. You do not eat during the collections, and you do not exercise through them. The review visit afterward often runs 30 to 60 minutes depending on the plan. The test itself is the longer, quieter part, done at home with a timer.

Lactulose and glucose are different substrates. Glucose is absorbed earlier in the small intestine, so it may miss a problem farther down. Lactulose travels farther and can be fermented by ordinary colon bacteria if transit is fast, which is one way a graph gets confusing. Dr. Tara Kohen picks the substrate from the question, not from whichever kit is on the shelf.

The day before is a prep diet, plain foods the instructions list, then a fast. The prep exists so leftover fermentable food does not light up the baseline. Skipping the prep is a common reason a graph is unreadable. If you cannot do the diet because of another medical need, say so before you start. A botched prep is worse than a delayed test.

A rise in hydrogen or methane after the drink means fermentation happened, and the timing suggests where along the gut that fermentation was likely. An early rise is the pattern people mean when they say small intestinal bacterial overgrowth. A late rise can be ordinary colon fermentation, especially with lactulose. Methane is associated, in many people, with slower transit and constipation. Hydrogen is often discussed with looser stools.

SIBO as a label should follow the graph and the symptoms together. Bloating that is clearly tied to meals is part of the story. Brain fog by itself is not a reason to declare overgrowth. GI-MAP stool testing looks at stool organisms and inflammation markers. It does not draw this gas curve. The two tests are allowed to disagree, and the disagreement is discussed rather than averaged.

False positives happen. A fast transit time can make colon gas look early. A prep that was not followed can raise the baseline. A substrate that does not match the question can overcall or undercall. Dr. Sani Kohen will say when the graph is messy. A messy graph is not rounded up into a treatment just so the test feels worth the fee.

Symptoms decide whether a borderline rise is acted on. A dramatic rise with a matching story is more useful than a small wiggle in someone who feels well. The lab fee is an additional cost, explained before you order, without a fictional price. A free 20-minute consultation can decide if breath testing is the right question. FRI is out of network, accepts HSA and FSA cards, and provides a superbill for the visit.

Expect a quiet morning at home with a timer, a drink that may taste plain or slightly sweet, and tubes or a device you breathe into on schedule. The prep diet the day before is part of the test. Set the day aside. Results are reviewed in person so the timing of the rise can be explained on the graph, not in a one-line message.

You should leave the review knowing whether the pattern was early, late, hydrogen, methane, or too messy to use. Next steps, if any, are matched to that pattern and to how you actually feel. A test that does not match the story is allowed to be set aside.

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.

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.

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.
