What causes yellow stool? Is yellowish stool normal? Discover the potential symptoms, possible causes, and when to see a gastrointestinal care provider for yellow poop.

The Digestive Process and Bowel Movements

The digestive process begins when you eat and continues as your body pulls the nutrients it needs from food. The end product is a bowel movement that can vary in color, odor, size, and consistency each time. These variations can provide clues about your body’s processes, organs, and overall health.

Why is Stool Usually Brown?

Bowel movements are usually a shade of brown. The contents of a bowel movement are waste products from your body, including food residue, digestive organ secretions, bacteria, and byproducts of old red blood cells. These old red blood cells are broken down in the spleen, liver, and bone marrow. These cells can look green, yellow, or brown as your body processes them. Bilirubin, a byproduct of red blood cells, ends up giving bowel movements the characteristic brown color.

What Causes Yellow Stool?

Yellowish brown or yellow bowel movements may be alarming, but in many cases, changes in color can be attributed to diet. Food that is high in yellow pigment or containing artificial food coloring can cause yellow bowel movements. Taking antibiotics can also make bowel movements yellow. If the discoloration is due to food or medication, it should resolve within a day or two after discontinuing the culprit.

When is Yellow Stool a Concern?

If yellow bowel movements become the new normal or are accompanied by other symptoms, there may be an underlying pathology that can be addressed with treatment or medication. Yellowing of the skin and/or whites of the eyes (called jaundice), pain, or fever, accompanied by yellow stool should always be followed up by a healthcare provider.

Diseases and Conditions that Cause Yellow Stool

Yellowish bowel movements can be caused by a variety of processes in the abdominal organs. Diseases of the liver, the bile ducts, or the pancreas can cause symptoms like light, clay-colored stool, dark urine, jaundice, and itching. Less common conditions like fat malabsorption can also lead to yellow, foul-smelling stool.

When to See a Gastrointestinal Care Provider

If changes in stool color persist for several weeks or cannot be explained by food or medication, it’s a good idea to see a gastrointestinal care provider. They can evaluate your symptoms and order tests to determine the underlying cause. Seeking medical attention is especially important if you experience severe symptoms like fever, dizziness, or persistent diarrhea.

Does yellow stool always indicate a serious problem?

No, yellow stool does not always indicate a serious problem. In many cases, changes in stool color can be attributed to diet or medication. If the discoloration is temporary and resolves on its own, it’s usually not cause for concern. However, if yellow stool becomes the new normal or is accompanied by other symptoms, it’s a good idea to see a healthcare provider to rule out any underlying conditions.

What are some common causes of yellow stool?

Some common causes of yellow stool include:
– Eating foods high in yellow pigments or artificial coloring
– Taking antibiotics
– Diseases affecting the liver, bile ducts, or pancreas (e.g., cirrhosis, gallstones, pancreatitis)
– Conditions that impair fat digestion or absorption (e.g., celiac disease, short bowel syndrome, giardiasis)

When should I be concerned about yellow stool?

You should be concerned about yellow stool if:
– It persists for more than a few days
– It is accompanied by other symptoms like abdominal pain, weight loss, jaundice, or diarrhea
– It is accompanied by fever, dizziness, or severe/persistent diarrhea

In these cases, it’s a good idea to see a healthcare provider to determine the underlying cause and receive appropriate treatment.

How can I tell if my yellow stool is caused by something serious?

There are a few key things to look for that may indicate a more serious underlying condition causing yellow stool:
– Persistent yellow stool that doesn’t resolve within a day or two
– Accompaniment of other symptoms like abdominal pain, weight loss, jaundice, or diarrhea
– Presence of fatty, foul-smelling stool
– Concurrent symptoms like fever, dizziness, or severe/persistent diarrhea

If you notice any of these, it’s best to see a gastrointestinal care provider for further evaluation and diagnosis.

What should I do if I have yellow stool?

If you have occasional yellow stool that can be attributed to your diet or medication, there’s usually no need for concern. The discoloration should resolve on its own within a day or two.

However, if the yellow stool becomes persistent or is accompanied by other concerning symptoms, it’s a good idea to see a healthcare provider. They can perform any necessary tests to determine the underlying cause and provide appropriate treatment. Don’t hesitate to seek medical attention, as yellow stool can sometimes indicate a more serious gastrointestinal issue that requires evaluation and management.

The digestive process begins when you eat and continues as your body pulls the nutrients it needs from food. The end product is a bowel movement that can vary in color, odor, size and consistency each time. These variations can provide clues about your body’s processes, organs, and overall health. Yellow bowel movements might give you a hint that something is going on with your diet or your body.

Why is stool usually brown?

Bowel movements are usually a shade of brown. The contents of a bowel movement are waste products from your body, including food residue, digestive organ secretions, bacteria, and byproducts of old red blood cells. These old red blood cells are broken down in spleen, liver, and bone marrow. These cells can look green, yellow, or brown as your body processes them. (Think of how a bruise transitions from brown, to green, to yellow as your body heals. ) Bilirubin, a byproduct of red blood cells, ends up giving bowel movements the characteristic brown.

What causes yellow stool? Is yellowish stool normal?

Yellowish brown or yellow bowel movements may be alarming, but in many cases changes in color can be attributed to diet. Food that is high in yellow pigment or containing artificial food coloring can cause yellow bowel movements. Taking antibiotics can also make bowel movements yellow.

If you’ve eaten something or taken medication that affected the color of your bowel movement, you’ll notice your next bowel movement will look more normal. The discoloration should fully resolve in a day or two after discontinuing medication.

If yellow bowel movements are infrequent, there probably isn’t much cause for concern. If yellow bowel movements become the new normal or are accompanied by other symptoms, there may be an underlying pathology that can be addressed with treatment or medication. Yellowing of the skin and/or whites of the eyes (called jaundice), pain, or fever, accompanied by yellow stool should always be followed up by a healthcare provider.

What diseases or conditions cause yellow stool?

Yellowish bowel movements can be caused by a variety of processes in the abdominal organs.

Most people experience abdominal or stomach pain from time to time, but when abdominal pain is accompanied by yellow bowel movements, this can indicate a bile drainage disorder.

Diseases of the liver, the bile ducts, or the pancreas can cause these symptoms:

• Light, clay-colored stool
• Dark urine
• Yellowing of the skin and eyes (jaundice)
• Itching (pruritus)
• Less common: Fatty stool (steatorrhea) / weight loss with fat malabsorption

Liver-related causes of yellow stool

Chronic liver diseases including alcoholic fatty liver disease, alcoholic hepatitis, cirrhosis, viral, hepatitis, and other diseases impact liver function.

These diseases can impair bile production and delivery (excretion). In severe episodes, a person might experience fatigue, flu symptoms, and epigastric pain.

Biliary tract-related causes of yellow stool

Gallstones are hard, stone-like pieces of cholesterol and bilirubin that form in your gallbladder and can clog bile ducts.

Around 10 to 15 percent of adults in the United States have gallstones, although many people with gallstones don’t experience symptoms. When gallstones block the bile ducts, people can experience severe abdominal pain on their right side. The bile duct blockage might lead to a build-up of bile in the gallbladder. The gallbladder and bile ducts can become inflamed. This is called cholecystitis and cholangitis.

During acute episodes, in addition to upper abdominal pain, fever, and chills can occur. Jaundice, dark urine and light or fatty stool may occur under some circumstances.

Other conditions that can affect the biliary tract include non-bacterial inflammation with autoimmune diseases, like primary biliary cholangitis (PBC) or primary sclerosing cholangitis (PSC). About 75 percent of people with PSC also have ulcerative colitis and 13 percent have Crohn’s disease. Symptoms are often absent, but persistent itching may occur.

Pancreas-related causes of yellow stool

Diseases of the pancreas, like the chronic inflammation of the pancreas (chronic pancreatitis), can lead to build up of bile, e.g. because of a bile duct compression or narrowing. This can be related to excessive alcohol consumption, autoimmune disorders, too much calcium in the blood (hypercalcemia). The main symptom is recurrent, belt-shaped upper abdominal pain. Other symptoms like nausea, vomiting, weight loss, jaundice, light and fatty stool, and jaundice may occur under some circumstances. This happens because the pancreas is damaged and can no longer produce the fat-splitting enzyme lipase.

Tumors that might cause yellow stool

Tumors that narrow the bile ducts are usually painless. Masses can occur in the bile ducts inside and outside the liver, the liver, and the pancreas. Painless jaundice may be a warning sign. Weight loss, night sweats, and unexplained fever can also occur.

What is fatty stool (

steatorrhea)?

Bile works by digesting fat in the intestine. If the body cannot digest or absorb enough fats, for example—due to a lack of bile salts or of the enzyme lipase—it excretes them instead in stool. This might manifest as a greasy, shiny bowel movement with a distinct, pungent smell. Fatty bowel movements often float in the toilet. If this problem persists for an extended period of time, it may lead to weight loss.

In case of fatty stools, the underlying condition should be treated. Dietary intake of fat-soluble vitamins can be increased by taking nutritional supplements.The absorption of fats is completed in the last part of the small intestine. Bowel diseases like celiac disease can lead to indigestion with fatty stool, weight loss, and abdominal pain.

Yellow diarrhea

A particularly common cause of abdominal pain are infections of the gastrointestinal tract, which cause pulpy, liquid bowel movements. Here, diarrhea occurs when the brown stool is thinned and can appear lighter in color.

There may also be mucus in the stool. Mucus acts as lubricant and keeps the intestinal inner lining moist. A small amount in bowel movements is normal. However, if you notice an increased amount or it is accompanied by abdominal pain, fever, or headache, seek evaluation from a primary care or gastroenterology provider.

Infants and yellow stool

Breastfed infants will have yellow, crumbly bowel movements. This is normal for infants. Bowel movement color should remain consistently yellow until a baby begins eating table foods. Any changes in bowel movement color in an exclusively breastfed infant should be followed up with a pediatric care provider.

What to do if you have yellow stool

Occasional yellow bowel movements are likely to be caused by diet. If yellow bowel movements become frequent, there may be an underlying condition responsible. A primary care provider or gastroenterologist can evaluate your symptoms and run lab tests to identify the cause of yellow bowel movements. If yellow bowel movements are accompanied by pain, fever, or jaundice, seek health care promptly.

Yellow Poop: Causes, Meaning, and Treatment

It’s common for your stool to change color. You likely have a varied diet, and changes in your diet impact your stool. But yellow stool could also mean one of a number of health conditions.

Bilirubin and bile give poop its brown color. Bilirubin is a byproduct of your red blood cells. It’s produced in the liver and then moves to the gallbladder, where it mixes with bile.

From there, most of the bilirubin passes into your intestines, where it’s broken down by bacteria and discarded in your feces or urine.

Several health conditions can cause yellow stool, also called pale stool.

1. Liver and gallbladder disorders

Cirrhosis of the liver and hepatitis reduce or eliminate bile salts that help the body digest food and absorb nutrients. Gallstones or sludge in the gallbladder can reduce the amount of bile that reaches your intestines. Not only may this cause pain, but it can also turn your stool yellow.

2. Disorders that affect the pancreas

Chronic pancreatitis, pancreatic cancer, a blockage in the pancreatic duct, or cystic fibrosis can also turn your stool yellow.

These conditions can cause steatorrhea, which means that your pancreas isn’t providing enough of the enzymes your intestines need to digest fat in food. The undigested fat can give the stool a yellow, greasy appearance causing it to float or appear frothy.

3. Celiac disease

Gluten is a protein found in wheat, rye, and barley. If you have celiac disease and eat gluten, your body’s immune system responds by attacking and damaging the tissues of your small intestine. When this happens, your intestines aren’t able to absorb the nutrients your body needs. Celiac disease commonly runs in families.

According to the National Foundation for Celiac Awareness, more than 250 symptoms are associated with celiac disease. This can make it difficult to diagnose the condition. The most common symptoms include:

• diarrhea
• constipation
• nausea
• bloating
• fatigue
• headache
• skin rash
• loss of bone density
• depression

Although there is no cure for celiac disease, it can be treated effectively by eliminating gluten from your diet.

4. Gilbert’s syndrome

Gilbert’s syndrome is a genetic liver disorder characterized by periods when bilirubin levels are too high. The U.S. National Library of Medicine reports that Gilbert’s syndrome affects 3% to 7% of Americans. Symptoms of the disorder, primarily mild jaundice, are so mild that many people don’t know they have it. Gilbert’s syndrome is usually left untreated.

5. Giardiasis

Giardiasis is an infection of the intestinal tract by a microscopic parasite called giardia. You get giardiasis by ingesting giardia cysts. These are typically ingested with your food or water.

Symptoms of giardiasis may include:

• foul-smelling diarrhea that is often yellow
• stomach cramps
• nausea
• headache
• Low grade fever
• weight loss

Giardiasis is diagnosed by testing a stool sample. Although some people don’t require treatment, most are given antibiotics. Giardiasis often lasts several weeks. Giardiasis may become chronic, though this is rare.

Giardiasis is a common disorder worldwide. According to the Centers for Disease Control and Prevention (CDC), giardiasis is the most widespread intestinal parasitic infection in the United States.

Q:

When changing my baby’s diaper, sometimes his stool is yellow. Is this normal? If not, how should I treat it?

A Healthline reader

A:

Yes, yellow stool can indicate a shorter transit time of food through the intestinal tract. Different colors (darker) can indicate that transit time is slowing. It is not uncommon for stool to change colors. If you notice blood or diarrhea, you should notify your doctor immediately, as these may herald a serious health issue.

Is yellow poop normal?

Yellow poop can be your body’s typical reaction to what you eat. Some causes of this are eating foods high in food coloring, carrots, or sweet potatoes. It may also be from certain gluten products or a diet high in fats. That said, if it’s happening chronically, you may want to see a doctor to exclude an underlying medical cause.

Does yellow poop mean infection?

Yellow poop can be caused by giardiasis, which is a bacterial infection. However, it’s not the only possible cause.

Can Covid-19 cause yellow poop?

Research shows that people who experience diarrhea as a symptom of Covid-19 can have yellow stool. This is likely due to your body not having enough time to digest your food.

Your bowel movements may differ in color, depending on what you’ve eaten recently. But if your stool is yellow, it could be indicative of a medical condition.

If you are having yellow poop, especially if you are noticing it frequently, see your doctor for an evaluation. Many things can cause yellow stool, and it’s a good idea to find the cause in case you need treatment.

Diarrhea treatment

Yellow diarrhea as well as diarrhea a different color, does not apply to independent diseases. But this condition may indicate a malfunction in the gastrointestinal tract, problems with the liver and gallbladder, infectious diseases, intoxication, or other health problems that require timely and proper treatment.

Causes of yellow diarrhea

Loose stools that are bright yellow or mustard in color can be caused by the following diseases and conditions.

Intestinal infection . The causative agents of infectious diseases of the intestine can be viruses (with enterovirus, rotavirus infection, etc.), bacteria (with cholera, salmonellosis, dysentery), bacterial toxins (with toxic infections), as well as fungi and protozoa. They enter the body along with contaminated food, water, or if personal hygiene requirements are not observed. Also, the source can be poorly washed or long-term stored food, toys, household items, food products that have not undergone heat treatment. The disease can develop rapidly and be quite difficult (frequent urination and loose stools quickly lead to dehydration and other complications).

Food poisoning . It can occur when eating inedible or poisonous mushrooms, spoiled dishes. With improper storage of products (especially fermented milk), non-compliance with sanitary requirements during the preparation of various dishes, staphylococcus aureus, E. coli and other pathogenic microorganisms can multiply in them. In the course of their life activity, pathogenic microorganisms release many toxins, which poison the human body, having entered it with contaminated food.

Food allergy . Food allergies are often accompanied by digestive disorders. Gastrointestinal manifestations of such a reaction in a child or adult may include pale yellow diarrhea, severe flatulence, nausea, etc.

Other causes. Light yellow diarrhea can occur with problems with the gastrointestinal tract, including the liver and gallbladder, enzymatic pancreatic insufficiency. It also appears with excessive consumption of dairy products, especially if a person suffers from lactose intolerance. Also, such a chair is sometimes found in infants whose diet is represented mainly by breast milk or milk mixtures.

Associated symptoms

Diarrhea rarely develops as the only symptom of a gastrointestinal disorder or disease. In addition to diarrhea, the following manifestations of the underlying pathology may also be observed.

Necessary measures

What to do with yellow diarrhea should be decided by the doctor after a preliminary examination and a complete examination.

Treatment

In the treatment of diarrhea, it is important to eliminate the cause of this symptom and normalize bowel function in order to stop the loss of water and electrolytes and the development of other negative consequences. To understand the overall clinical picture and key aspects of the patient’s health, a medical examination is carried out, based on the results of which the doctor prescribes treatment. It may include taking various groups of drugs, including antibiotics, antidiarrheal drugs, lacto- and bifidobacteria, rehydrating solutions, enterosorbents, etc. The specific names of the drugs, their combination as part of complex treatment, the dosage and duration of the course of therapy are prescribed by the doctor.

IMODIUM

Yellow stools: when to sound the alarm

Yellow stools are not the main symptom of Crohn’s disease, but there are a number of causes that lead to its occurrence and require a visit to the doctor. It is important to understand why this condition occurs, and how and when to sound the alarm.

In some cases, it is possible to notice yellow mucus on the outer surface of the stool, which may completely or partially cover the stool. The body produces mucus to protect the inner lining of the intestines and facilitate the excretion of metabolic products, so the appearance of only a small amount of it is not a cause for concern, as an independent symptom.

However, if the stool turns yellow regularly all the time, it may be a sign of an underlying disease, such as a lesion of the pancreas, liver or gallbladder disease. If a person only occasionally notices yellow stools, it may be the result of a change in diet or stress.

This article explains whether yellow stool is a symptom of Crohn’s disease, its possible causes and treatment.

1. 1 . Fully yellow

Bad-smelling and yellow-colored stools can be a sign that the digestive system is not absorbing nutrients properly. Malabsorption, in particular, can occur due to Crohn’s disease. If the stool is too greasy in consistency, has an unpleasant odor, this may indicate a violation of fat absorption. This can happen in Crohn’s disease if the end section of the small intestine that passes into the large intestine is affected. It is possible to prevent the development of a pronounced malabsorption by avoiding aggravating foods, as well as by regular visits to the doctor.

2. 2 . Yellow coated

The presence of yellow mucus in the stool may be a typical symptom of Crohn’s disease and appear as streaks or completely cover the stool. If yellow mucus in the stool is not accompanied by new symptoms, this is not a cause for concern for people with Crohn’s disease.

3. In children

Periodic yellowish stools in a child may be a sign of normality, but, together with an increase in volume and a change in consistency to a more liquid, yellow color may indicate diarrhea, both food and infectious origin. Diarrhea in children may be due to a diet low in fat and high in sugar or fluids. Drinking too much fruit juice or other sugary drinks can lead to this condition.

If diarrhea persists, this may indicate the onset of Crohn’s disease or one of the following conditions:

– celiac disease

– lactose intolerance

– parasitic infections such as giardiasis or cryptosporidiosis

– food allergies

– diseases of the pancreas glands

– excessive activity of the thyroid gland.

4. Diet

Foods high in fat pass through the digestive tract faster and may cause loose, yellow stools. This is especially true for people who usually do not eat a lot of fatty foods. Foods containing yellow food coloring can also give feces a yellow tint.

5. Hologenic diarrhea

This is a type of chronic diarrhea that affects 1 in 100 people and is caused by excess bile acids in the colon. Most often, this condition occurs due to a violation of the absorption of bile acids in the small intestine or during their rapid transit due to increased motor-evacuation function of the small intestine.

Other symptoms include:

– prolonged, painful, liquid diarrhea

– feeling of urgent need to void

– frequent stools, often at night

– flatulence

– abdominal cramps

6. Giardiasis

This is an intestinal parasitic infection that can be contracted by ingesting contaminated food or water. It can cause a range of symptoms, including:

– diarrhea

– strong, foul-smelling, greasy stools

– sensation of pain, abdominal cramps

– nausea

Flatulence

Dehydration

Early symptoms include fatigue and two to five loose bowel movements per day. Patients may also experience fever, swelling of the joints, and itching of the skin. Treatment usually involves taking antiparasitic drugs.

7. Celiac disease

This is a condition in which intestinal damage and malabsorption occur when eating food containing gluten. Symptoms vary from person to person, but most commonly can include:

Loose, greasy, profuse, foul-smelling, yellow stools

– Persistent diarrhea

– Flatulence

– Lactose intolerance

– Nausea and vomiting

9 0002 – Abdominal pain

Treatment includes a gluten-free diet.

8. Pancreatic disease

Various disorders of the pancreas, such as chronic pancreatitis, cysts or neoplasms, can prevent the body from properly absorbing the nutrients in foods. This malabsorption can cause loose, yellow, strong-smelling stools due to the inability to properly excrete pancreatic enzymes and indigestion.
