Why Your Kid’s Stomach Won’t Stop Growling In Class (It’s Not Always Hunger)
I was leaning against the back hatch of our dusty Outback last Tuesday when 9-year-old Milo wrenched the passenger door open hard enough to slosh the leftover apple juice in his cup holder. He dumped his neon dinosaur backpack on the floor mat, stared at the scuffed toe of his sneaker, and said he was never going back to fourth grade math.
I turned down the radio and waited. It took him three blocks to get the whole story out. They’d been taking a timed multiplication test that afternoon, the room so quiet you could hear the hum of the overhead lights. First it was a soft gurgle, the kind he could pass off as the kid two seats over. Then it got louder, a long, rumbling growl that cut through the silence. The boy across the aisle made a fake Godzilla roar under his breath, half the class snickered, and his teacher paused mid-direction to glance in his direction. Milo said he’d pressed his fist as hard as he could into his gut, held his breath until his eyes burned, and prayed for the floor to open. It just kept growling.
My first thought was that he’d skipped breakfast or blown his snack on the way to class. But I’d made him two peanut butter waffles that morning, and he’d eaten both plus a clementine before we left the house. He swore he’d finished his entire granola bar at 10:15 snack time, and the test was at 1:45, right after lunch. He’d gotten the school pepperoni pizza that day, eaten the whole slice, the side of carrot sticks, the chocolate milk, and even the mini chocolate chip cookie I’d tucked into his lunchbox. He wasn’t hungry.
I knew exactly how he felt. When I was in seventh grade, my stomach growled so loud during silent reading in social studies, my teacher asked if I needed to run to the cafeteria five minutes early. I wanted to crawl under my desk. I started skipping lunch twice a week after that, convinced an empty stomach would be a quiet stomach. All that did was make the growls louder and more frequent, and left me lightheaded by last period.
I emailed Milo’s teacher that night, not to complain, just to say he’d come home pretty embarrassed and ask if this was something that popped up a lot. She wrote back within an hour, and said it’s far more common than most parents realize. Three or four kids in her class deal with loud stomach growls on a weekly basis, and she’s had multiple kids ask to visit the nurse for fake stomach aches just to get out of the quiet room after a particularly loud one. For years she’d just told the whole class “it’s just your body digesting, no big deal,” but she’d learned that line does nothing to erase the humiliation of 25 pairs of eyes turning to look at you.
We brought it up at his yearly well visit a week later, and his pediatrician didn’t even blink. She said the technical term is borborygmi, but it’s just the normal sound of gas and muscle movement working through the intestines. The biggest myth most people buy into is that growling only happens when you’re hungry. Your gut moves that gas around whether you’ve eaten or not, and an empty intestine is often louder, because there’s no heavy food to muffle the sound.
She walked through the small, boring triggers that add up for most school-aged kids. A lot of it lines up with the rush of the school day: kids chug their entire milk or soda in five minutes at lunch so they can bolt outside for recess, swallowing extra air that gets trapped later. Sugar-free gum and candy sweetened with sorbitol, the kind a lot of kids trade from their lunchboxes, cranks up gas production for hours. Sitting still for 40 or 50 minutes straight during tests or independent work slows everything down, too. And the biggest cycle of all: when a kid is already tense and waiting for the next growl, they suck in their stomach and hold their core tight, which traps gas and makes the rumbles even louder.
She noted that if the growls come with regular pain, constipation, diarrhea, or unexpected weight loss, it’s worth checking for food sensitivities or other gut issues. For most kids, though, it’s just normal body function made worse by the structure of the school day.
We didn’t overhaul his whole diet or turn the classroom upside down to fix it, just made a handful of tiny changes that added up. The first and biggest: Milo had been chewing sugar-free mint gum a friend gave him every day after lunch, and it was loaded with sorbitol. He swapped that for a plain peppermint hard candy without the sweetener, or just a quick sip of water, and cut the frequency of bad growl days in half almost immediately. We stopped packing broccoli and chickpeas in his lunch, too—we have those at dinner, when he can run around the front yard with the neighbor kids for an hour after eating instead of sitting straight down for quiet work. We tried shoving an extra granola bar in his bag to eat right before math at first, but that just made his gut work overtime and made the rumbles worse; regular, spaced meals work far better than cramming extra food to muffle noise.
His teacher made two small shifts in the classroom, no big assembly or public callout required. She already had a soft lo-fi piano playlist she used for writing workshops, so she started playing it at a near-whisper for all tests and independent work periods. It’s quiet enough no one gets distracted, but it muffles all the small, random body noises—coughs, sneezes, stomach growls, even scraping chair legs—so no single sound cuts through the silence. She also rolled out a no-questions hall pass rule: any kid can hold up two fingers, step outside, get a drink, and walk one slow loop around the fourth grade hallway, no explanation needed. She told the whole class it was for anyone who felt wiggly after sitting too long, so no one ever connected it to Milo.
At home, I skipped the generic “don’t be embarrassed, no one cares” line, because I remembered caring very much. I told him the full story of my seventh grade social studies growl, and gave him a one-line script to use if anyone glances over when it happens: “Just my stomach digesting.” No long apology, no hiding, just a shrug and back to work. We practiced it a few times in the car, overexaggerated and silly, until it felt natural to say.
It’s been six weeks now, and it’s not gone entirely. Some days he says he doesn’t notice it at all. A couple weeks ago, it rumbled mid-read aloud, the kid next to him glanced over, Milo said his line, and the kid nodded and turned back to the book. Other days, usually when he has a hard quiz or rushed through lunch to get in an extra kickball game, it acts up. Last Wednesday he stepped out into the hallway twice during math, and grumbled about it the whole drive home, called it the most annoying thing about fourth grade. We compromised on chocolate milk this week—only on Fridays, instead of every day—after he threw a minor fit when I suggested cutting it out entirely.
Last night I found him leaning against the kitchen counter after dinner, one hand splayed over his stomach, breathing in slow and out slow like his gym teacher taught them for test anxiety. He said he’s going to try doing that for a minute before math starts, to see if it keeps gas from getting stuck. I don’t know if it’ll work. But it feels like enough for now, that he’s got small things he can try, and he doesn’t have to sit hunched over his multiplication worksheet holding his breath, waiting for the next rumble.
