Seeing "corn-like" bits in your poop without eating corn is usually harmless undigested fiber from other high-fiber foods (veggies, seeds, nuts) or even pill casings, but it could be a sign of faster transit (like a stomach bug) or digestive issues like IBS if frequent or accompanied by diarrhea, weight loss, or other symptoms; chew food better, and see a doctor if worried or symptoms persist.
Sometimes, you may see undigested food fragments in stool. This usually is high-fiber vegetable matter, which usually isn't broken down and absorbed in your digestive tract. At times, undigested food is a sign of poor chewing and fast eating.
Corn is a particularly frequent culprit because of its outer shell, made of cellulose. The body lacks enzymes to break down cellulose. However, it can digest the inner contents of the corn kernel. If you notice what seems like whole kernels in your stool, it's likely just the outer shell.
Foods such as corn often remain partially undigested. Corn has an outer shell made of an indigestible material called cellulose. The body digests the material inside of the corn and expels the hard outer casing into the stool.
It is common to see whole pieces of sweetcorn in poo. Obvious food can sometimes be more visible if the poo is very loose. This is usually caused by not chewing food thoroughly enough. The gut has no means of breaking down tough pieces of food after it has been swallowed.
Change in the Appearance of the Stool
A Thin, narrow, or ribbon-like stool could indicate changes inside your colon. Color: Blood, darkened, or tarry (black) stool can signal issues inside the colon. Your doctor can help determine the cause.
IBS poop varies greatly, often fluctuating between hard, lumpy, and difficult-to-pass stools (IBS-C) and loose, watery, and urgent stools (IBS-D), or alternating between both (IBS-M), sometimes with mucus present, but not blood. Shapes can range from small pellets to thin, pencil-like forms, and color might shift due to speed of passage (e.g., green/yellow for fast, darker for slow).
Gallstones may range in size from a grain of sand to the size of a golf ball. They resemble small stones, and may appear black, dark blue, or yellow-green in color, depending on whether they contain bilirubin or cholesterol.
Diverticulitis causes several noticeable changes in your poop, including altered color (bright red, maroon, or black), different shapes (thin, pellet-like, or irregular), and unusual texture (watery diarrhea or hard constipation).
Mushy stool with fluffy pieces that have a pudding-shaped consistency is an early stage of diarrhea. This form of stool has passed through the colon quickly due to stress or a dramatic change in diet or activity level. When mushy stool occurs, it's hard to control the urge or timing of the bowel movement.
Narrow, pencil-thin stools caused by material having to squeeze past an obstruction. Hard pebbles or nuggets that occur because of cancer-related constipation cause waste to remain in the colon longer and have more water removed from it. Dark brown or black color throughout caused by blood in the stool.
Symptoms of different malabsorption syndromes can vary. They often include chronic diarrhea, abnormal stools, weight loss, and gas. Your doctor may use lab, imaging, or other tests to make a diagnosis.
Bacterial gastroenteritis is a digestive problem caused by bacteria. Symptoms include nausea, vomiting, fever, diarrhea, abdominal cramping, and pain. In severe cases, you may become dehydrated and have an electrolyte imbalance.
Crohn's disease can change the way your poop looks and smells. It may be loose, hard, oily, pale, bloody, or foul-smelling. It can also change how often you have bowel movements. Poop changes alone cannot diagnose Crohn's disease, however, they can signal inflammation.
Pale Poop and Dark Pee
If your liver doesn't make bile normally or if the flow from the liver is blocked, your poop will look pale like the color of clay. Pale poop often happens along with yellow skin (jaundice). The extra bilirubin that makes your skin look yellow also can make your pee unusually dark.
Symptoms that are common to both Crohn's disease and ulcerative colitis include:
Symptoms of intestinal failure may include:

When To Call the Doctor
Most people who think they may have a leaky gut have certain common gastrointestinal symptoms, such as abdominal pain, food sensitivities, bloating and indigestion.
"If (someone) has a bowel movement and it's so clean and well-formed that it doesn't leave any residue and just sinks, that is actually a very healthy bowel movement," says De Latour.
