Why Does My Poop Smell Like Cheerios?
Have you ever noticed your poop smells kind of like Cheerios? If so, you may be wondering whats causing your stool to have this distinctive odor. There are a few possible explanations why your poop smells similar to the popular breakfast cereal.
Diet as a Factor
One of the most common reasons your poop smells like Cheerios is your diet. Cheerios are made with oats, corn and wheat. When you eat foods containing these grains, some of the food compounds can make their way through your digestive system unmodified and get excreted in stool.
Your poop can take on the smell of fermented or undigested grains. The sweet, yeasty aroma resembles that of Cheerios. So if you've eaten any foods containing oats, corn or wheat recently, this may explain the Cheerios-esque smell.
Other Starchy Foods
It's not just Cheerios themselves that can make your poop smell this way. Other starchy or whole grain foods can also contribute to the distinctive cereal-like odor.
Foods like pasta, rice, bread, oatmeal and cereals contain carbohydrates that can ferment in the digestive tract and alter stool smell. Consuming lots of starchy foods may result in poop that smells sweet like corn or has aromatic malty notes.
Probiotics
Another possible dietary explanation involves probiotics. Probiotics are beneficial live bacteria that are added to certain foods like yogurt, kefir and fermented foods. They can also be taken as supplements.
When probiotics make their way through the GI tract, they can change the bacterial environment and affect the smell of stool. The yeasty, fermented scent of probiotics may make poop smell like cereal or beer.
Malabsorption
Certain medical conditions can cause food malabsorption, meaning nutrients from food aren't being properly absorbed in the intestines. Lactose intolerance, celiac disease and Crohns disease are examples.
When malabsorption is present, undigested carbohydrates end up in the colon and can make poop smell sweet and malty. The Cheerios scent may indicate an underlying absorption issue.
Small Intestinal Bacterial Overgrowth
Small intestinal bacterial overgrowth (SIBO) is a condition where excess bacteria grow in the small intestine. This can interfere with proper digestion and absorption.
SIBO may sweeten the smell of stool due to fermentation and undigested carbs. The bacteria produce gas as a byproduct of fermentation which can also contribute to the Cheerios-like smell.
When to See a Doctor
While cereal-scented poop is typically harmless on its own, in some cases it may signal an underlying health condition that needs medical attention. See your doctor if the symptom persists along with:
Diarrhea
Ongoing diarrhea along with sweet smelling stool can indicate a problem with nutrient absorption. Celiac disease, Crohns disease and lactose intolerance can cause diarrhea.
Weight Loss
Unintentional weight loss along with poop smell may be a sign of celiac disease or inflammatory bowel disease like Crohns. Getting proper nutrition is important.
Bloating or Abdominal Pain
Bloating, gas, abdominal cramping or pain may occur with conditions like SIBO, irritable bowel syndrome or inflammatory bowel diseases.
Other Symptoms
Additional red flags include symptoms like fatigue, joint pain, rashes, anemia and malnutrition. Seek medical care if you have ongoing poop smell concerns along with other worrisome symptoms.
Tips to Reduce Cheerios Poop Odor
If bothersome or persistent, here are some tips that may help minimize stool smelling like Cheerios or other cereals:
Avoid Problem Foods
Keep a food diary and limit foods that seem to make your poop smell cereal-like, such as grains, dairy, probiotic foods or large amounts of starchy carbs. Following a low FODMAP diet may help.
Increase Digestive Enzymes
Try taking over-the-counter digestive enzyme supplements containing amylase, lipase and proteases to help break down carbs, fat and protein.
Take Probiotics
Try taking probiotic supplements to restore a healthy gut microbiome. Look for broad spectrum probiotics containing strains like Lactobacillus and Bifidobacterium.
Treat Underlying Conditions
If you have SIBO, IBS, celiac disease or other conditions, work with your doctor on proper treatment to prevent malabsorption and reduce odd-smelling stools.
Stay Hydrated
Drink plenty of liquids, especially water, to help stay regular and move stool through the colon more efficiently.
Increase Fiber Intake
Eat more fiber from fruits, vegetables, beans, nuts and seeds to add bulk to stool. But increase slowly to avoid bloating.
When Poop Smell Should Concern You
While cheerio-like poop smell is usually harmless, certain foul odors may be a sign of a health problem. See your doctor if your poop has an abnormally bad odor described as:
Rotten Egg or Sulphur Smell
This can indicate hydrogen sulfide gas produced by gut bacteria. A sign of IBS or infection.
Fishy Smell
An especially foul, fish-like odor may signal underlying infection or bacterial overgrowth.
Fecal or Sewer Smell
An especially offensive, fecal odor could mean an internal fistula or abscess.
Sickeningly Sweet Smell
A nauseatingly sweet stench may indicate uncontrolled diabetes or a digestive issue.
While smell alone doesnt diagnose a condition, a severely abnormal odor warrants mentioning to your doctor.
When to See a Gastroenterologist
In some cases, it may be helpful to see a gastroenterologist (GI doctor) for evaluation of ongoing poop smells, especially when combined with other symptoms. A GI specialist can help diagnose and treat conditions like:
Celiac Disease
Damage to the small intestine caused by gluten. Requires a gluten-free diet.
Inflammatory Bowel Disease
Crohns disease or ulcerative colitis. May require medications or surgery.
Irritable Bowel Syndrome
IBS causes digestive issues like diarrhea, constipation, cramping and bloating.MANAGED lifestyle and sometimes medications.
Small Intestinal Bacterial Overgrowth
SIBO causes bloating, diarrhea and nutritional deficiencies. Treated with antibiotics, probiotics and dietary changes.
A gastroenterologist can order diagnostic tests like bloodwork, stool tests, endoscopy, colonoscopy or CT scan to get to the root of any odor and absorption issues.
When Poop Smell Isn't a Concern
In most cases, Cheerios smelling poop is not considered abnormal or unhealthy. Stool can take on a wide range of scents based on your diet and gut microbiome. Here are examples of when cereal-like poop odor is likely benign:
No Other Symptoms
If your poop smells like cereal but you lack diarrhea, pain, or other issues, its likely just dietary in nature.
Smell Goes Away
If the cheerio odor resolves after stopping probiotics or reducing your grain intake, its not a major concern.
Odor Comes and Goes
Poop smell varies day-to-day and isnt a problem as long as no other symptoms arise.
No Changes in Bowel Habits
Stool smell alone without constipation, diarrhea, changes in frequency or other issues is usually normal.
While bothersome, poop that smells like cereal generally isnt harmful. But do pay attention to any accompanying symptoms or intestinal distress.
Maintaining Healthy Bowel Habits
To stay regular and minimize unpleasant poop odors in general, focus on the following healthy bowel habits:
Drink Plenty of Fluids
Stay well hydrated to keep your poop soft and bowel movements regular.
Eat More Fiber
Fill up on high fiber foods like fruits, veggies, beans and whole grains to support healthy pooping.
Take Probiotics
Probiotic foods or supplements populate your gut with good bacteria to support digestive health.
Exercise Regularly
Aim for at least 30 minutes of activity per day to keep your digestion running smoothly.
Manage Stress
Find healthy stress relief techniques like yoga, mindfulness and deep breathing to minimize GI issues.
Pay attention to how different foods affect your poop smell and adjust your diet accordingly. But typically cheerio-scented stool on its own is not a major health concern.

Yes, probiotics can cause yeasty, fermented smells in stool due to the live bacteria strains. This is harmless, but reducing probiotic intake may help.
What does it mean if poop smells like chemicals?
A chemical poop smell, like ammonia or bleach, could indicate infection or bacterial imbalance in the colon. See a doctor if it persists.
Is smelly poop a sign of IBS?
