A person’s stool may be pale or white due to dietary choices, an infection, or an underlying medical problem, such as gallbladder or liver disease. People with persistently pale stools may need medical treatment.
If pale stools occur once with no other symptoms, it is usually safe to wait and see if the stool returns to its usual color.
That said, a child or infant with pale or white poop should see a doctor as soon as possible to rule out any underlying conditions.
In this article, learn about the causes of pale stool and other symptoms that may occur with them.
Bile from the liver, known as bilirubin, creates the typical brown hue of a healthy bowel movement. When the stool is very pale, it often means that not enough bile is reaching the stool.
Stools may contain low bile levels if there is a problem with the gallbladder, pancreas, or liver. People with consistently pale stools may want to talk with a doctor about conditions that affect these organs.
The most common reasons for a pale stool color include:
Some foods, such as fatty foods, may cause stool color to become yellow.
The occasional pale bowel movement is unlikely to be a cause for concern. Changing the diet may cause poop to return to its usual color.
Giardiasis, also known as beaver fever, is an infection that may turn the stool yellow. Symptoms can result from an infection with Giardia lamblia, an intestinal parasite. A person can contract this parasite by drinking contaminated water or coming into contact with soil or stool that contains the parasite.
Giardiasis is present around the world, including all parts of the United States, according to the
Other symptoms of giardiasis include:
Many drugs and medications can damage the liver, especially with high doses.
Pale stools may be a sign of liver damage in a person who:
- is taking a new drug
- has been taking medication for some time
- is taking high doses of a drug
With OTC drugs, it is best to stop taking the drug and see a doctor as soon as possible. For prescription drugs, people should speak with their doctor before stopping the drug.
4. Gallbladder disease
The gallbladder holds bile and is located on the upper right side of the stomach, next to the liver. During digestion, the gallbladder releases bile into the intestines through the bile duct. Gallbladder diseases can change the color of stool.
Gallstones, one of the most common gallbladder diseases, can block the bile duct.
As well as pale stool, it
Without treatment, gallstones can cause problems with other organs, such as the pancreas and liver.
Treatments for gallbladder problems depend on the cause. A doctor may have to remove gallstones, either surgically or with medication to dissolve them.
A person can live without a gallbladder, so a doctor may remove it if gallstones keep returning. The person may need to change their diet after surgery.
5. Liver problems
Problems with the liver or bile ducts can turn the stool pale.
When a person has liver or biliary problems, bilirubin is unable to pass in the stool. This causes the stool to lose its color, giving it a more pale or clay-colored appearance.
Conversely, the body excretes excess bilirubin in the urine, giving it a darker or amber-colored appearance.
There are many types of liver disease, including:
- infectious diseases, such as hepatitis A, B, and C
- liver damage from alcohol consumption
- fatty liver disease, most common in those with obesity or who eat a high-fat diet
- autoimmune diseases, when the body attacks the cells of the liver
- failure of other organs
- liver cancer
- liver cysts
- Wilson’s disease, a genetic condition where the body retains too much copper
In addition to pale stool, other symptoms of liver disease include:
Anyone under a doctor’s care for liver disease should report any changes in stool color.
Treatment for liver disease depends on the cause and how far it has progressed.
For mild liver disease, a person may only need medication and lifestyle changes. Those with severe liver disease may need a liver transplant.
Sometimes problems with other organs — such as the gallbladder — lead to liver symptoms. In this case, a doctor must treat the underlying condition as well.
6. Pancreatic problems
Diseases of the pancreas can make it hard for this organ to secrete pancreatic juices into the digestive system. This can lead to the food moving too quickly through the gut, resulting in a pale and fatty-looking stool.
Examples of problems with the pancreas include pancreatitis and pancreatic cancer.
Both can involve jaundice, with the following symptoms:
- pale and fatty stools
- dark urine
- yellowing of the whites of the eyes
It can result from various conditions,
- autoimmune pancreatitis
- high alcohol consumption
- the use of some drugs
Chronic pancreatitis can also increase the risk of pancreatic cancer.
Treatment for pancreatitis depends on the cause. The doctor may address an underlying issue, such as gallstones.
Some people need hospitalization, intravenous fluids, and pain management. If a bacterial infection is present, a doctor may prescribe antibiotics.
In some cases, surgery may be necessary.
Pale stools in children are not necessarily a medical emergency if they occur once and are pale but not white.
Breastfed babies often have light yellowish-brown stools. Once they start transitioning to solids, their stool usually becomes browner.
When the stool is white or very light brown, this can signal a more serious problem, such as cholestasis, a type of liver disease.
In newborns, cholestasis or any other problem with the liver, gallbladder, or pancreas may be a medical emergency. A caregiver should call their pediatrician right away.
If the baby has other symptoms, turns yellow, or appears to be in pain, they must go straight to the emergency room.
In older children who have no other symptoms, it is usually safe to wait for the next bowel movement.
White or clay-colored stools during pregnancy usually indicate a problem with the gallbladder, liver, biliary ducts, or pancreas. Some people develop a pregnancy-related liver disease called cholestasis of pregnancy.
Symptoms of cholestasis include pale stool as well as:
- intense itchiness
- pain under the ribs on the upper right side of the stomach
- dark urine even when hydrated
- exhaustion beyond that of a typical pregnancy
- jaundice, or yellowing of the eyes, fingernail beds, or skin
Treatment can include medication and frequent monitoring, including blood work and ultrasound scans. In some cases, an early delivery might be necessary.
A doctor will ask some questions and may carry out a physical examination.
They may ask:
- When did you first notice this symptom?
- Are all your stools pale?
- What medications do you use?
- Do you have any other health conditions?
- Do you have any other symptoms?
To investigate pale stools, a doctor may recommend the following tests:
- blood tests to assess liver function and look for signs of infection
- endoscopic retrograde cholangiopancreatography (ERCP)
- imaging studies, such as an abdominal ultrasound, a CT scan, or an MRI of the liver and bile ducts
The outlook will depend on the cause of pale stools.
If a person’s stools are pale because of certain foods or supplements, changing the diet or regime will usually help.
The outlook for pancreatitis varies. In around
For people with pancreatic cancer, the chance of surviving 5 years or longer after diagnosis is around
Various factors can lead to pale stools. It is not always possible to prevent pale stools, but people can lower the risk of developing certain diseases, such as pancreatitis and pancreatic cancer.

To reduce the risk of liver disease, a person can:
Diseases of the liver, gallbladder, and pancreas can quickly become life-threatening, but they are usually treatable.
If symptoms arise, such as pale stools, it is best to seek help as soon as possible, as leaving them can lead to lasting damage and complications.
Sometimes a person passes one pale stool, and then the usual color returns. If pale stools persist, it is best to seek medical advice promptly, especially if there are other symptoms, such as dark urine, vomiting, or fever.
Here are some answers to questions people often ask about pale stool.
What does pale or light colored stool mean?
Pale stools can indicate problems in the liver, bile ducts, gallbladder, or pancreas. Dietary factors can also play a role. Giardiasis, a parasitic infection, can cause yellow stools.
Is it serious?
Without treatment, the conditions underlying pale stools can be serious or lead to severe complications. Anyone with persistently pale stools should seek medical advice.
Is it ok to have pale stool sometimes?
Some causes of pale stool are temporary and harmless. For example, the large amounts of the active ingredient in antacids can cause pale stools. However, if stools do not quickly return to normal, it is a good idea to contact a doctor.
What is pale stool in medical terms?
The medical term for pale or light colored stools is acholic stool.
What does your stool look like with pancreatic cancer or pancreas problems?
Issues with the pancreas can make food move through the gut too quickly, causing pale, fatty-looking stools.
Bowel movements reveal important information about a person’s health. One pale stool is not usually a matter of concern, but frequent pale stools can indicate diseases of the liver, pancreas, or gallbladder.
In some cases, treatment can help a person feel better within a few days or weeks. Other underlying conditions require long-term management.
