Yellow Diarrhea: Causes, Treatment and Prevention

Your stool color says a lot about your gut and overall health.

Your gut processes ingested food, absorbs nutrients and discards the waste products which we see as stool. Normal poop is formed, soft and brownish in color.

When one passes frequent loose stools – more than three loose stools in the space of twenty-four hours, it is described as diarrhea.

Yellow diarrhea is the passage of frequent loose yellow colored stools.  In this article, we will examine the causes of yellow diarrhea, its treatment, and prevention. You can also check out this stool color chart that explains what different stool colors mean.

Causes Of Yellow Diarrhea

A change in the color or frequency of poop is often met with worry, especially if it persists. There are many causes of yellow diarrhea, some are quite harmless while some are serious. Below are some common causes:


1. Diet

colored food

Your diet affects your poop color, texture, and quantity. Eating food items with coloring may cause you to pass bright yellow stools. These food items, such as candy, carrots, turmeric, sweet potatoes or processed food items may cause you to pass yellow stools but this goes away after a short time.

2. Liver and Gall bladder Diseases

liver disease

In Liver cirrhosis and inflammation (called hepatitis), the liver fails to produce sufficient bile to help the body digest fatty acids, causing these food items to pass through the gut largely unchanged, causing the poop to be discolored.

In other instances, the liver produces enough bile but there may be a problem with its delivery due to a gall bladder stone, thus reducing the bile that gets into the intestines for digestion.

3. Celiac Disease


This is an autoimmune disease that causes some food particles to pass undigested through the digestive tract. In autoimmune diseases, the body’s immune system inadvertently attacks the body. Celiac disease affects gluten digestion (a protein found in food items such as barley, wheat, and rye).

When you ingest these food items that contain gluten, the body attacks the cells in the small intestine, damaging them and ensuring that these food items are not digested.

4. Pancreatic Diseases


The pancreas is an important organ in digestion. It produces chemicals called enzymes that help break down food in the intestine. When diseased, the process of digestion is less efficient and you may pass yellow, bulky stools. Common diseases that affect the pancreas include pancreatitis (acute and chronic), pancreatic cancer, or cystic fibrosis.

5. Infection of the Digestive Tract

An infection of the digestive tract may cause the passage of bright yellow watery stools. Disease-causing entities are ingested in unclean or contaminated food or water. One of the common causative organisms is Giardia. In addition to causing yellow stools, you may also pass foul smelling farts, feel nauseous and have stomach cramps.

Treatment of Yellow Diarrhea

medical testing

Before treatment, your doctor will ask you questions, taking note of the onset of your yellow diarrhea, the frequency of stools, as well as other complaints.

Your doctor will then proceed to examine you before requesting for some tests which may include a blood test to assess your blood counts, stool test and culture to check if your symptoms are of an infectious origin, ultrasound scan or computed tomography scan.

These will lead him/her to make a diagnosis and give adequate treatment and care. Stress and anxiety may also cause you to have yellow diarrhea, if this is suspected, your healthcare provider may refer you to a mental health expert.


Treatment is tailored to help you revert to optimum health. It is offered via medications, lifestyle decisions, and dietary modifications. In severe cases, you may require surgery. Once treatment is completed, you should be back to your normal health or as close to it as possible.

In the immediate period, however, your healthcare professional will assess your level of dehydration and then advise you to drink more fluids or set up an intravenous drip for you. Thereafter, medications are prescribed as appropriate. You should see your doctor immediately if:

  • You develop sudden severe stomach pain
  • You are dizzy
  • You have foul-smelling stools or farts
  • You have a fever
  • You are confused
  • You have persistent or recurrent symptoms
  • You have stool mixed with blood


properly cooked meal

Here some tips to prevent you from developing yellow diarrhea:

  1. Eat properly cooked meals wherever you are but especially when you are abroad
  2. Include more fiber in your meals
  3. Avoid triggers in your diet. This is especially important if you have allergies to a particular food item, such as gluten in celiac disease.
  4. Avoid eating food items with lots of coloring
  5. Wash your hands thoroughly when you go to the toilet and before preparing or eating food.



In conclusion, yellow diarrhea is usually a consequence of your dietary choices. In some cases, it is a pointer to an underlying and potentially worrisome disease affecting the gut or the whole body. It is imperative to go see a doctor if you have yellow diarrhea especially if it is a recent change.

You should also follow the aforementioned steps in order to prevent yourself from passing yellow colored stools.
