Fatty stool, known as steatorrhea, is typically pale yellow or clay-colored, greasy, bulky, and has a foul smell, often floating and being difficult to flush due to undigested fats, indicating issues with fat absorption from diet, pancreas, or bile. While occasional fatty stool can follow a very high-fat meal, persistent fatty stools suggest a medical problem like malabsorption, requiring a doctor's visit, say Guts UK.
Fatty poops are different from normal poops. They tend to be looser, smellier and paler in color, like clay. They might float. You might have an occasional fatty poop after eating a fatty meal.
Yellow, fatty poo often smells bad too and can be described as 'greasy'. People with Irritable Bowel Syndrome (IBS) can sometimes have symptoms when they eat fat in their diet. However, steatorrhoea might indicate the fat that is eaten in the diet is not being absorbed well.
Normal Stool Color
Any shade of brown, green or yellow is possible and normal, from light beige to dark green. In some instances, food is not entirely digested, so it can be chunky or have whole pieces in the diaper.
Chronic diarrhea is often the first symptom prompting one to seek medical evaluation, although diarrhea need not be present for one to have malabsorption. Steatorrhea, or fatty stools, is indicative of malabsorption. Stools will be frothy, foul smelling, and a ring of oil may be left on the toilet water.
If your stool suddenly becomes pale or clay-colored, it could indicate a blockage in the bile duct. It may also suggest a liver issue, such as fatty liver disease.
Patients with steatorrhea present with bulky, pale, foul-smelling oily stools. These fatty stools tend to float in the toilet bowl and often challenging to flush as well. In the early stages, steatorrhea may be asymptomatic and go unnoticed.
Poop that's red or black is often most alarming as it could suggest bleeding (not always). If your poop doesn't go back to brown or changes colors often, it could mean something else is going on.
Ask a healthcare professional if you're concerned about your stool color. If your stool is bright red or black — which may indicate the presence of blood — seek medical attention right away. Food may be moving through the large intestine too quickly, such as due to diarrhea.
You may have clay-colored stools if you have a liver infection that reduces bile production, or if the flow of bile out of the liver is blocked. Yellow skin (jaundice) often occurs with clay-colored stools. This may be due to the buildup of bile chemicals in the body.
Floating poop caused by fat malabsorption looks like greasy and oily stool. You might notice oil floating in the toilet with your stool, and it may even stick to the toilet bowl. In some cases, this can result in an orange-colored stool. ”The medical term for this condition is steatorrhea.
A Quick Review. Yellow poop is usually a sign of fat malabsorption or restricted bile flow. It can indicate conditions related to your liver, pancreas, or gallbladder. Eating yellow-pigmented or fatty foods may cause yellow poop and is not a cause for concern.
How Oily Stool Is Treated
Giardiasis is an infection caused by a parasite called Giardia. It causes diarrhea. Symptoms include explosive, watery, greasy, foul-smelling stools, bloating, nausea, pain, gas, fatigue, and loss of appetite.

Even though early colon cancer might not cause any signs, here are some stool changes that could be warning signs: Blood in your stool. You might see bright red blood or very dark, black, tarlike stool. Blood from lower down in your colon or rectum is usually red.
Poop red flags signaling a need to see a doctor include ** blood in or on the stool**, black/tarry or pale/grey stools, persistent diarrhea or constipation (over 2-3 days/weeks), severe abdominal pain/cramps, unexplained weight loss, foul odor, or a sudden change in bowel habits/urgency, as these can point to issues from minor problems like fissures to serious conditions like Inflammatory Bowel Disease (IBD) or colorectal cancer, says Healthdirect and Cancer Research UK.
Fiber gives your stool good consistency – on either end of the spectrum. If you have hard stools fiber holds water in to make them softer and relieve constipation. If you have looser stools, fiber adds bulk to give stools shape and form. The best type of consistency is a banana shape.
Stools that are pale, clay, or putty-colored may be due to problems in the biliary system. The biliary system is the drainage system of the gallbladder, liver, and pancreas.
The colour of your poo can depend on what you eat and drink, medications and the time food has spent in your digestive system. Black may indicate certain medication use, like iron supplements, or undigested food. Light to dark brown may indicate an ideal and healthy stool.
Some of the symptoms of fatty stools include:
Fat malabsorption
Fats that aren't absorbed in your small intestine pass to your colon, causing fatty stools (steatorrhea). Fatty stools are greasy and runny and particularly smelly. They may be light-colored and float. Fat malabsorption also leads to the malabsorption of fat-soluble vitamins (A, D, E and K).
