One pale stool is not usually a matter for 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.
The liver releases bile salts into the stool, giving it a normal brown color. 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.
White stool isn't normal and should be evaluated promptly by a doctor. White or clay-like stool is caused by a lack of bile, which may indicate a serious underlying problem.
The only colors that may relate to disease are red, black and white. All other colors are not due to a medical problem. Normal stools are not always dark brown. Sometimes they are light brown, tan or yellow.
Gray or Clay-Colored Stool
The stool can be gray or clay-colored if it contains little or no bile. The pale color may signify a condition (biliary obstruction) where the flow of bile to the intestine is obstructed, such as obstruction of the bile duct from a tumor or gallstone in the duct or nearby pancreas.
Pale stools could be a sign of liver damage, as pale, clay, beige or sand coloured stool may be a sign that your body, most notably your liver is not producing enough bile, or it may not be draining bile properly. Bile makes up part of the colouring of your stool.
Normally, stool is brown, but people with bile duct cancer may have pale or clay-colored stools that are oily and float in water. Also known as cholangiocarcinoma, bile duct cancer is a type of rare cancer that starts growing in the bile ducts. Bile is needed to break down fats during digestion.
Carrots, sweet potatoes, turmeric, and foods that contain yellow food coloring may cause stool to become yellow. A diet high in fat or gluten can also lead to yellow stool. If a person regularly has yellow stools, they should try avoiding fatty, processed foods, gluten, or anything that causes an upset stomach.
Light-Colored Poop
If your poop is light-colored, yellow, clay-colored, or very light brown, this may be a sign of: An infection or inflammation (swelling) in your gallbladder, liver, or pancreas. Alcoholic hepatitis, which is inflammation in your liver caused by alcohol consumption.
Tumors: Benign or malignant tumors affecting the bile flow can cause pale stools. Narrowing of the Bile Ducts: Gallbladder surgery can sometimes cause narrowing of the bile ducts affecting the bile flow. Giardiasis: Giardiasis is an infection caused by the parasite giardia lamblia. Giardiasis can cause pale stool.
Fatty liver disease: If you notice dark urine and pale poo, seek urgent medical attention.
Anxiety does not specifically affect the color of stool, but it can affect how food moves through the digestive tract.
If your stool is not normal-colored (light or dark brown), it means you have some gut issue, whether it's just food that didn't sit right, food poisoning, or a virus. But sometimes it can be a sign of bleeding (red/black stool), or a liver or gallbladder issue (very pale stool), so don't ignore a discoloration.
A person should also see a doctor if their symptoms get progressively worse, stools are pale, bulky, very offensive smelling and difficult to flush away (this may indicate a problem with absorbing fat), or if they are concerned about their symptoms.
If your pale stools are caused by something structural, like blocked bile ducts, you may need surgery to remove the blockage or widen the passageway. Hepatitis may require antivirals, while a liver transplant is the only way to resolve cirrhosis.
Pale stool (yellow or grey) can signify a problem with the liver or gallbladder, so if you have persistently light-coloured stool, then you should see your physician.
All shades of brown and even green are considered normal. Only rarely does stool color indicate a potentially serious intestinal condition. Stool color is generally influenced by what you eat as well as by the amount of bile — a yellow-green fluid that digests fats — in your stool.
The color of stools varies, but typically falls within the spectrum of brown color, depending on the foods you eat. You should be concerned if your stools are deep red, maroon, black, or "tarry," especially if they have a noticeable odor. This may mean that there is blood in the stool.
Yellow stool can indicate that food is passing through the digestive tract relatively quickly. Yellow stool can be found in people with GERD (gastroesophageal reflux disease). Symptoms of GERD include heartburn, chest pain, sore throat, chronic cough, and wheezing.
If a tumor blocks the pancreatic duct, insufficient pancreatic juices in the intestines can lead to poor absorption and diarrhea, as the undigested food passes quickly through the digestive tract. If this happens, stool may float due to the higher fat content, appear bulky, greasy, and unusually pale.
Yellow diarrhea can mean several things. It could be caused by a problem with one of your digestive organs, including your liver, gallbladder, or pancreas. It could also be caused by a germ, like a bacteria or virus, or a parasite.
Stomach cancer can present itself in several different ways, such as difficulty swallowing, feeling bloated after eating, feeling full after only eating a small amount of food, heartburn, indigestion, nausea, stomach pain, unintentional weight loss, and vomiting.
