Stool comes in a range of colors. 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. As bile pigments travel through your gastrointestinal tract, they are chemically altered by enzymes, changing the pigments from green to brown.

Consult your doctor if you're concerned about your stool color. If your stool is bright red or black — which may indicate the presence of blood — seek prompt medical attention. Michael F. Picco, M.

Should I be concerned?

Answer From Michael F.You have yellow diarrhea and you have lots of questions in your head.

Watery Yellow Diarrhea - Causes, Symptoms and Treatment

Why is it yellow? Should I be worried? Should I go to the doctor? What is causing this? This article has been written to address some of these questions and provide answers because lets face it, when we look into the toilet bowl we expect to see brown whether it is diarrhea or not and seeing another color can be a bit alarming.

Normal poop is brown because as it moves through the intestines friendly bacteria work on the bile pigment billirubin which derives from haemaglobin. After a long complicated process a new end product, a pigment called stercobilin, is formed which gives it its brown color. If your poop moves too fast this process does not have time to happen and you end up with yellow poop.

So basically yellow is the normal color of poop near the beginning of the process it starts out greenish and it needs time to change color.

There can be many different reasons why you still have yellow poop when you have a bowel movement. Can stress cause diarrhea? Well most of us know that it can and just because you have yellow diarrhea it does not mean that you are ill. As we all know anxiety can bring on diarrhea and if the bowels speed up a lot then the diarrhea will be a yellow color as you will be seeing the poop from higher up in the intestines before it has had time to change color.

Why do we get diarrhea when we are anxious? Well our bodies learned to react to threats at a time when our ancestors were in danger of being eaten by wild animals and other ancient dangers. When we are threatened our blood is diverted to the muscles and in particular to the legs and arms so that we can either fight or run away.

At the same time it diverts blood away from the digestive system and stops it working because it is deemed to be low priority when faced with a life threatening danger. This is called the 'fight or flight' response and it is regulated by the sympathetic nervous system.

This system is outside our conscious control. Your bowels stop digesting food and also stop sucking the fluid from your liquid poop back in and firming it up which is one of its jobs. Apparently your body also thinks that emptying your bowels at this precise moment is a good idea so that you will not have to stop mid fight or flight to go! I think this is somewhat of a design fault and would rather have constipation than sudden diarrhea at this moment but this is the model we are stuck with and it often happens, usually preceded by some abdominal pain which is a sign of the bowel contracting strongly.

Of course we are no longer confronted with sabre tooth tigers but unfortunately in our modern world our bodies are still on the lookout for dangers and so some people will have annoying nervous systems that interpret as dangers other things like exams, flying, mice in my case or just the everyday stresses of our high energy complicated modern lives.

So having yellow diarrhea does not always indicate a medical condition but rather a nervous system which is on high alert and perhaps a need to lead a less hectic life or to learn to 'rest and digest'.Bile acid diarrhea BAD is a condition in which bile acids are not properly processed within the digestive systemresulting in symptoms of chronic diarrhea.

This condition can also be known as bile acid malabsorption BAM. Researchers in this area believe that BAD is not as rare a condition as was once thought.

They also believe that BAD is an under-diagnosed condition—one that should be considered for anyone who is experiencing chronic diarrhea of unknown cause—in particular, people who have the symptoms of diarrhea-predominant irritable bowel syndrome IBS-D or functional diarrhea.

The problem with this under-diagnosis is that it may prevent people from getting proper treatment. Bile acids are produced by your liver and stored in your gallbladder. When you eat foods containing fat, these acids are released into the small intestine so the fats can be broken down and absorbed into your body. Bile acids are then reabsorbed at the level of the small intestine back into the liver for re-release as needed.

However, when BAD is present, excessive amounts of bile acids are flushed into the large intestine. This leads to increased fluid secretion, resulting in watery stools and a speeding up of intestinal motility—both of which end with symptoms of diarrhea. Although it had been thought that the dysfunction involved malabsorption, more recent research suggests that the problem might actually be an overproduction of bile acids. This may be due to a dysfunction in the feedback loop that should inhibit the production of bile acids.

BAD manifests primarily as the experience of chronic bouts of diarrhea. Given the new look at the role of inhibition of the feedback loop for the synthesis of bile acids, the term idiopathic bile acid malabsorption I-BAM may go out of favor.

A repeat scan is scheduled seven days later. The capsule contains SeHCAT, which is used to assess the ability of the small intestine to retain bile acids. A retention rate lower than 15 percent is considered to be indicative of the presence of BAM. Unfortunately, the test is not available in the United States. One downside of this is that one of the primary medications used for BAD is not well-tolerated.

It is considered the most direct way to identify patients with BAD. Studies indicate that BAD might be behind approximately one-third of cases of IBS-D and 40 to 50 percent of cases of functional diarrhea.Your stool colour may change depending on what you eat.
