Diarrhea is a common condition that can vary in color, providing clues about underlying health issues. Understanding what different colors of diarrhea mean can help you determine when to seek medical attention.

What Causes Different Colors of Diarrhea?

Diarrhea can be caused by a range of factors, including diet, infections, and medical conditions. The color of diarrhea can provide insight into its cause:

• Brown: Normal color, indicating healthy digestion.
• Green: Often due to consuming green foods or rapid transit through the intestines.
• Yellow: May indicate a gallbladder or liver issue, especially if accompanied by a foul odor.
• Black: Could suggest bleeding in the upper gastrointestinal tract.
• Red: Often a sign of bleeding in the lower gastrointestinal tract.
• White or Pale: May indicate a bile duct obstruction or liver issue.

Why Is My Diarrhea Green?

Green diarrhea is usually not a cause for concern. It can result from:

• Diet: Eating large amounts of green vegetables or foods with green dyes.
• Bile: Rapid transit through the intestines can prevent bile from breaking down completely, resulting in a green color.
• Infections: Certain bacterial infections can cause green diarrhea.

What Does Yellow Diarrhea Indicate?

Yellow diarrhea can be a sign of:

• Fat Malabsorption: Conditions like celiac disease or chronic pancreatitis can cause fat malabsorption, leading to yellow, greasy stools.
• Infections: Giardiasis, a parasitic infection, often results in yellow diarrhea.
• Liver or Gallbladder Issues: Problems with bile production or flow can cause yellow stools.

Is Black Diarrhea a Medical Emergency?

Black diarrhea can indicate serious conditions, such as:

• Upper GI Bleeding: Bleeding from ulcers or the stomach can cause black, tarry stools.
• Iron Supplements: Taking iron supplements can darken stool color.
• Medications: Some medications, like bismuth subsalicylate (Pepto-Bismol), can cause black stools.

If you experience black diarrhea, especially with dizziness or weakness, seek medical attention immediately.

What Causes Red Diarrhea?

Red diarrhea can be alarming and may be due to:

• Lower GI Bleeding: Conditions like hemorrhoids or diverticulitis can cause red stools.
• Diet: Consuming red-colored foods or drinks can temporarily color stools red.
• Infections: Some infections can cause red diarrhea due to inflammation and bleeding.

Why Is My Diarrhea White or Pale?

White or pale diarrhea can suggest:

• Bile Duct Obstruction: Conditions like gallstones or tumors can block bile flow, leading to pale stools.
• Liver Disease: Liver conditions, such as hepatitis, can affect bile production.
• Medications: Certain antacids containing aluminum hydroxide can cause pale stools.
