What gives yellow colour to feaces?

Question

Answer

The pigment present in the bile juice named biliverdin  gives color to the faeces

Answer

The colour is yellow because of bilirubin pigment present in the bile juice

Answer

It is yellow because of bile juice present in gall bladder...

Answer

Gallstones or sludge in the gallbladder reduce the amount of bile that reaches your intestines. Not only may this cause pain, but it can also turn your stool yellow.

Answer

Deposition of bile pigments

Answer

Although the color of feaces can be affected by different foods and medications, it is typically brownish due to digestion of bile salts, digestive agents made by the liver and stored in the gallbladder.

A reduction or absence of bile salts can cause the feces to become yellow or pale.

Answer

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 reduce the amount of bile that reaches  intestines which is yellow due to presence of bilirubin.

Answer

Bilurubin

Answer

Whether it is billiverdin or billirubin

Answer

Introduction:
The color of feces can vary depending on several factors, including the person's diet, hydration levels, and the presence of certain medical conditions. The typical color of feces is brown, but it can also appear in shades of yellow. In this response, we will explain the factors that contribute to the yellow color of feces.

Dietary factors:
One of the primary reasons for yellow-colored feces is the intake of certain foods and beverages. Some foods contain pigments that can pass through the digestive system and affect the color of the stool. For example:

1. Carotenoids: Foods rich in carotenoids, such as carrots, sweet potatoes, and squash, can give a yellowish hue to the stool. Carotenoids are plant pigments that are not completely broken down during digestion, resulting in their presence in the feces.

2. Artificial food coloring: Consuming foods or drinks with artificial food coloring, particularly yellow or orange dyes, can also lead to yellow-colored feces. These dyes are not absorbed completely by the body and are excreted in the stool.

Bile pigments:
The yellow color of feces can also be attributed to the presence of bile pigments. Bile is a digestive fluid produced by the liver and stored in the gallbladder. It contains bilirubin, a yellow pigment derived from the breakdown of red blood cells.

1. Normal bile production: When the liver produces an appropriate amount of bile, bilirubin is excreted into the intestines and gives feces their characteristic brown color. However, if there is a decrease in bile production or if the flow of bile is obstructed, the bilirubin may not be fully converted to its brown form, resulting in yellow-colored feces.

2. Liver or gallbladder disorders: Various liver or gallbladder disorders can impact the production, flow, or metabolism of bile, leading to yellow-colored feces. These conditions include hepatitis, cirrhosis, gallstones, and liver or gallbladder cancer.

Medical conditions:
Certain medical conditions can also cause yellow-colored feces due to alterations in the digestive process or the body's ability to absorb nutrients. These conditions may include:

1. Malabsorption: Conditions like celiac disease, Crohn's disease, and pancreatic insufficiency can interfere with the absorption of fats, leading to increased fat content in the stool. This can give the stool a yellow or greasy appearance.

2. Infections and inflammation: Infections or inflammation in the gastrointestinal tract, such as gastroenteritis or inflammatory bowel disease, can affect digestion and absorption, resulting in changes in stool color.

Conclusion:
The yellow color of feces can be influenced by various factors, including dietary choices, bile pigments, and certain medical conditions. While occasional yellow-colored stools are usually not a cause for concern, persistent changes in stool color should be evaluated by a healthcare professional to rule out any underlying conditions.
