How Anna, a Denver art teacher, cured her IBS after six years and every diet.
Six years of post-infectious IBS-D after spring-break food poisoning in Mexico. Two colonoscopies. Two years of a formal Low FODMAP diet. Two $2,800 courses of rifaximin for SIBO. $2,800 in functional medicine supplements. Fourteen probiotics. Roughly $9,400 out of pocket. Then an Instagram ad and an $89 app her second GI had already named in his plan of care.
Anna is a 29-year-old Denver art teacher. She got IBS after food poisoning in Mexico in 2019. Six years later, after a Low FODMAP diet, two rounds of rifaximin for SIBO, four months of functional medicine supplements, two colonoscopies, and about $9,400 spent, she tried gut-directed hypnotherapy through an $89 app. Ten months later her symptoms were gone. In a 2024 randomized trial of the Nerva app in 240 IBS patients, 81% met the primary endpoint for meaningful symptom improvement, compared to 63% of the active control group.
Halmos et al., 2024, American Journal of GastroenterologySix years of diets, supplements, antibiotics, and two colonoscopies that came back perfect.
Anna was 23. Spring break 2019, senior year. She flew from Chicago to Playa del Carmen with three friends. On day four she ate street tacos her friends said were fine. By that night she was in the hotel bathroom with food poisoning. Fourteen hours of vomiting and diarrhea. She lost eight pounds in two days. Couldn't fly home with her friends. Three days later she flew back alone, dehydrated and weak.
Her mother, an ER nurse at Northwestern, picked her up at O'Hare and took her to an urgent care that gave her IV fluids and ciprofloxacin. The acute illness cleared inside a week. Her gut didn't go back. Three or four bathroom trips every morning for the first month. Her mother said give it time. After three months it was urgent diarrhea, bloating, and cramping most mornings. After six months it had become the new baseline. Anna called it "a sensitive stomach since Mexico" for almost two years before she called it IBS.
The ladder started with primary care. Probiotics, a food diary, the word "post-infectious" and the note that most cases resolve in six to twelve months. Hers didn't. Dairy cut. Gluten cut. Celiac panel negative, 2020. She stayed gluten-free another eight months anyway, just in case. Dicyclomine before meals for four months cut the cramping a little and dried her mouth out. First GI on a three-month wait. Colonoscopy, December 2020. Biopsies normal. Upper endoscopy normal. Inflammation markers normal. "Everything looks great. This is IBS. Try Low FODMAP."
Low FODMAP turned out to be a full year with a dietitian. An initial 90-minute session, six follow-ups, the elimination phase, the re-introduction phase, a personalized list. Wheat, onions, garlic, and high-lactose dairy came back as apparent triggers. Anna paid $1,130 out of pocket because the dietitian was out of network. She felt forty percent better. She was also afraid of onions. She stayed on the modified version for two years. Brought a cooler to Thanksgiving with her own food inside it. Declined dinner parties. Brought her own salad dressing to Michael's family reunion. Her Babcia made pierogi at Wigilia 2022 and Anna ate none of them. She said in halting Polish that her stomach couldn't. Her Babcia said "eat, Anna." Anna did not eat.
SIBO breath test in summer 2022, positive for hydrogen. Two weeks of rifaximin, $2,800 out of pocket because insurance denied the claim, paid anyway. Felt sixty percent better for six weeks. The symptoms came back. Second course in spring 2023, another $2,800, shorter benefit, about three weeks. A functional medicine doctor she found on Instagram charged $500 for intake, $420 for a GI-MAP stool test, and $286 a month for a 90-day protocol of L-glutamine, bovine colostrum, berberine, oregano oil, a 19-strain probiotic, digestive enzymes, and betaine HCL. Eleven pills with a breakfast smoothie every morning for four months. Some relief in month two. Gone by month four. Total with the functional route: $2,064.
Second gastroenterologist in January 2025 for a fresh set of eyes. Repeat colonoscopy, normal again. Celiac panel, negative again. CRP and fecal calprotectin normal. TSH normal. He suggested a low-dose tricyclic. Anna declined. He used the phrase "gut-directed hypnotherapy" and mentioned cognitive behavioral therapy as evidence-based brain-gut options. Anna dismissed the line in the car on the way home. He also said the words she had heard in different shapes from four different clinicians over six years. "Have you considered talking to someone about stress?" She cried in the parking lot before she drove away.
The wedding was six months earlier, June 2024. Italian restaurant in a small Vermont town. Michael's sister. Anna was a guest, five years into her IBS. She had planned around the buffet. Eaten at the hotel. Packed RXBars. Mapped the reception-hall bathroom. Took a small plate: rice, plain chicken, a dressing-less green salad. Twenty minutes in, during the toasts, she felt the warm flush that meant ninety seconds. She whispered "I have to go, I'm so sorry" and sprinted out in the middle of the maid of honor speech. Twenty-five minutes in the bathroom. When she came back, pale and shaking, Michael's mother was near her seat. "Oh honey, are you feeling okay? Are you pregnant?" Anna said no. She stepped outside and sat on a curb near the rental cars at dusk with reception music drifting out.
Michael found her ten minutes later. He sat down on the curb next to her. He said, "Anna. What do we do? We can't build a life around this." She said, "I know." He said, "I love you. I also need you to admit that what we've been doing for five years is not working." She said, "I think I'm scared that if the gut stuff isn't the answer, maybe there isn't one." He said, "Or maybe we've been trying to solve the wrong problem." That night in the hotel room she cried in a way she hadn't cried before. Not frustration. Grief. Michael sat next to her on the bed and didn't say anything. The next morning at the brunch, Anna told Michael's mother she had a gut condition. Michael's mother said, "Honey, my brother has Crohn's. You don't owe anyone an explanation."

An Instagram ad, an $89 app, and a line in her own GI's noteshe'd dismissed six months earlier.
Back in Denver on the Monday after the Vermont wedding, Anna went looking for something different. An Instagram ad for the Nerva app came through a month later. She had blocked most gut content over the years because it was all supplements. The headline on this one read "the gut-brain axis, explained." She tapped through out of tired curiosity and read the research page.
The program was six weeks of 15-to-20-minute gut-directed hypnotherapy sessions with short educational modules. Anna paid $89 for three months. She did the sessions on her lunch breaks in a kids' chair in her classroom, door locked, earbuds in. The first thing that shifted wasn't her symptoms. It was her understanding.
Three pieces clicked in the first two weeks. One: IBS is officially classified by the Rome Foundation as a Disorder of Gut-Brain Interaction. Not an alternative theory. The American Gastroenterological Association's 2024 IBS guidelines recommend brain-gut behavioral therapies for moderate-to-severe IBS. Anna's gut was not damaged. Her two colonoscopies and every inflammation marker had said so for years. What was dysregulated was the signaling between her gut and her brain. Her gut's nerves were sending pain signals in response to normal digestion, and her brain was reading them as threat.
Two: post-infectious IBS has a specific published pathway. About 10 to 15 percent of people who get acute gastroenteritis go on to develop chronic IBS. The Mexico infection had triggered a real inflammatory episode. That episode sensitized her gut's nervous system. The infection cleared in days. The sensitization hadn't. She'd been treating symptoms for six years without addressing the sensitization underneath them.
Three: her food reactions had been inconsistent for a reason she finally had a word for. Central sensitization means the brain's threat system modulates how the gut responds. When she was stressed, a tolerated food triggered a flare. When she was relaxed, a food on her "unsafe" list sometimes passed without issue. Her food log had been logging the wrong variable for six years. The variable wasn't what she ate. It was the threat level her nervous system was running.
Week three of the Nerva program. The session used a visualization of her gut as a river. "Your gut is safe. It has always been safe. The water flows normally." Anna cried in the kids' chair with her classroom door locked. Not from frustration. From understanding. She'd spent six years trying to fix something that wasn't broken. She wrote one line in the app's journal after the session. "My gut was never the problem. I've been trying to fix the wrong thing for six years."
Her second GI had used the phrase six months earlier and she had dismissed it. Gut-directed hypnotherapy. He had also mentioned CBT as an evidence-based option. She went back through the visit note on the patient portal that night. The words were right there in his plan of care. The line she needed had been in her own chart. She just hadn't been ready for it yet.
Functional
Two colonoscopies (2020 and 2025), both normal, biopsies normal. Celiac panel negative on two separate occasions. Upper endoscopy normal. CRP, fecal calprotectin, and TSH normal. Her gut was structurally healthy. Crohn's, colitis, microscopic colitis, celiac, and cancer were ruled out. The symptoms were generated by how her brain and gut were communicating, not by tissue damage. A 2025 meta-analysis in Neurogastroenterology & Motility found all twelve randomized trials of gut-directed hypnotherapy for IBS showed it worked better than control. Not most. All twelve.
Strong matchInconsistent
Gluten caused a flare on Mondays but not on Saturdays. Garlic triggered her at a work potluck and not at dinner with Michael. Symptoms worsened on Sunday nights before a school week and were measurably lighter over summer break. A four-day weekend at a Colorado cabin with no cell reception was almost symptom-free. Flares came back within hours of reception returning on Sunday night. A structural food intolerance doesn't know what day of the week it is. A gut in a sensitized nervous system does.
Strong matchTriggered
Flared before every parent-teacher conference week. Flared the week her father had a heart scare that turned out fine. Flared through Michael's sister's wedding weekend. Flared the morning of standardized testing at her school. Her food log showed no correlation between what she ate and when she flared. It showed a strong correlation between her week and her flares. Her gut was responding to her schedule, not her kitchen.
Strong matchWhat recovery actually looked like.
Not a clean slope down. A flare in month two during parent-teacher conference week felt for five days like the approach had stopped working. It hadn't.
IBS-SSS 285 (moderate). Started Nerva. Did 15-minute hypnotherapy sessions on lunch breaks and again before bed. Kept Low FODMAP for the first two weeks out of fear. Read the education modules. Understood "disorder of gut-brain interaction" for the first time, even though her second GI had used the exact phrase. Sat in a kid-sized chair in her classroom with the door locked and listened to a woman's voice tell her that her gut was safe.
IBS-SSS 185 (mild). Flares every two to three days, milder. Ate a bowl of pasta with onions and garlic. Nothing happened. Ate it again the next week. Also nothing. Let Michael take her to a real restaurant. Ordered pho. A mild rumble, no emergency. She told him that night, "I think this might be working." Stopped the modified Low FODMAP list. Threw out the food and symptom spreadsheet she'd kept for three years.
IBS-SSS 310. Parent-teacher conference week. A Monday flare that was worse than anything she'd had in months. Sprinted out of a meeting with a parent using the excuse of a "sudden migraine." Told Michael that night, "I think it's coming back. Maybe the app was a honeymoon." He looked at her and said, "Or maybe this is a flare and not a return." She kept doing the sessions. Didn't restart Low FODMAP. Didn't pre-medicate her next meal. The flare passed in five days. Two weeks later her baseline was better than before the week.
IBS-SSS 95 (mild). Flew to Chicago for Wigilia at her parents' house. Her Babcia made pierogi. Anna ate four. Also ate żurek and opłatek at the table. No flare. Her mother watched her eat, quietly, and started crying into a napkin. Her father asked what was wrong. Her mother said in English, "Anna's eating. For the first time in six years." Her father put his napkin down, looked at Anna, and said, "I didn't know that. I'm sorry. I should have known." Anna told him it was okay. It was the best Christmas of her life.
IBS-SSS 45 (normal range). Flew to Italy with Michael for 10 days. Rome, Florence, a small town in Tuscany. Pasta, pizza, cheese, wine, espresso, tiramisu, fried artichokes in Rome, tripe stew in Florence that she didn't expect to like and tried anyway. One mild flare on day six after an anxious travel-logistics morning. Cleared in three hours. Carried no RXBars. Didn't map a single bathroom. Ate where the waitress recommended, not where an IBS-friendly travel blog had rated.
IBS-SSS 30. Asymptomatic in practical terms. Painting in the studio she and Michael set up in the spare bedroom. Working on a series of watercolors of Colorado lakes. Teaching the K-5 art rotation through the last weeks of the school year. Realized over a morning coffee that she hadn't thought about her gut in two weeks. Not "hadn't flared." Hadn't thought about it. Told Michael over dinner. He said, "I was waiting for you to notice."
The three things that changed everything.
She stopped treating food like the enemy.
For six years every meal was a threat assessment. Anna read ingredient lists at restaurants. Carried RXBars, apple slices, and Low FODMAP granola bars in a tote bag everywhere. Brought her own salad dressing to dinner parties. Turned down her niece's birthday cake because she was "dairy intolerant." Her mental map had 47 items on the unsafe list and strict rules around combinations.
After, she ate what was on the table. Ordered what sounded good. Stopped carrying RXBars. Ate her Babcia's pierogi at Wigilia. Ate tripe in Florence because the waitress said it was good. Didn't eliminate anything she used to love. Her unsafe list went from 47 items to zero.
Treating food like the enemy had trained her brain to scan every meal for threats. The scanning itself was part of what kept her gut sensitized. Eating without fear told her brain a different sentence: this is food, not danger. Her gut followed the message.
She stopped planning her life around bathrooms .
Before, she had mapped every bathroom in her K-5 school by floor and proximity to her classroom. Checked restaurant bathroom access before agreeing to go. Canceled Friday night plans permanently under a "quiet-weekend rule for mental health" that was actually a Saturday-morning-bathroom rule. Didn't leave the house on weekday mornings until she'd had a "successful bowel event." Drove herself everywhere so she could leave fast.
After, she went to Italy. Ate dinner at 9 PM Italian style. Slept in on weekends without pre-planning her morning. Accepted a Friday night invitation from Michael's coworkers and went. Stopped checking bathroom access at restaurants. Carpooled to a wedding in Aspen. Ran an 8-mile trail outside Denver on a Saturday morning with no bathroom in sight.
Planning around bathrooms had told her brain that every environment was a place with limited escape. It reinforced the alarm every time she found an exit route. Stopping the planning told the brain the opposite. The body stopped running the emergency program.
Remove the middle link and the body stops running the emergency program.
She stopped being ashamed.
Before, she told almost no one. Not her coworkers. Not Michael's family. Not her father. Not her Babcia. She told her boyfriend's grandmother she was a "picky eater." Invented reasons to decline invitations. Lied about why she was leaving parties. Declined her Babcia's pierogi at Wigilia 2022 without a real explanation. Carried the shame of a private illness while smiling at four hundred children a week.
After, she told Michael's mother at the Vermont wedding brunch. Told her father at Wigilia. Mentioned it casually to a coworker during a faculty meeting. Recommended Nerva to a woman in an online IBS community who reminded her of her 24-year-old self. Started a Substack under her first name. Didn't over-explain. Didn't apologize. Let it be true.
The shame was its own nervous system load. Carrying a private illness while performing wellness was exhausting. Dropping the shame freed up capacity that had been spent maintaining a secret. That capacity went into recovery.
Back in her own body.
Anna has been effectively symptom-free for almost a year. Not flare-free. Symptom-free.
She eats normally. Pasta, pizza, cheese, wine, coffee, onions, garlic, Polish food at holidays. Runs an 8-mile Saturday trail in the foothills outside Denver. Trail, not road. The trail had been impossible for years because there are no bathrooms. She flew to Poland in fall 2025 to see her brother in Warsaw and spend a week in Kraków, her grandmother's hometown. First international trip since Mexico in 2019.
She teaches four hundred K-5 students a week without mapping bathrooms. Has a watercolor practice that's turning into something. Two gallery shows in Denver. She and Michael got engaged in April 2025, a week after she passed her own six-month nearly-asymptomatic mark. They're getting married next summer. She writes a Substack called "My Gut and Other Strangers" with 1,200 subscribers.
The residual flares are real. Every four to six weeks, usually around a high-stakes school event or a family stressor, she'll have a mild day. IBS-SSS in the 80-to-120 range. Gone the next morning. She doesn't cancel plans. She doesn't change what she's eating. She doesn't pre-medicate. Sometimes she does a Nerva session. Sometimes she notices it, lets it be there, and by the next day it's not.
"A flare used to be a catastrophe," she says. "I'd cancel three days of plans. Now it's a Tuesday that wasn't great. Sometimes I don't even tell Michael. I just notice it, let it be there, and the next day it's not there anymore. That's the part nobody sold me on. Not the absence of symptoms. The absence of the panic that used to follow them. I was a woman who mapped bathrooms at work and couldn't eat her grandmother's food. I'm a woman who eats pierogi and runs trails now. That's the recovery."
Does Anna's story sound familiar?
If your IBS started after a stomach bug, a year abroad, or a hard stretch of stress, and your colonoscopy is clean, your celiac panel is clean, your inflammation markers are clean, and your list of diets and supplements is long, there's a good chance your condition follows the same pattern Anna's did.
