The green feces may be the expression of several conditions and not pathological. In this article, we will give you a complete guide about why is my poop green? This symptom is often attributable to completely occasional changes related to diet or the intake of certain drugs. In some cases, however, green stools can signal the presence of some gastrointestinal or systemic disorders, especially if this manifestation does not tend to regress within a day or two.
Green stools are mainly seen when the passage of ingested food through the intestine is too rapid. This is the case, for example, with conditions that involve the onset of diarrhea. The accelerated transit does not allow the bile to be metabolized. Therefore to give the typical brown color to the stool. If the anomalous staining of the fecal material should repeat itself with a specific frequency or for a continuous period, it is advisable to investigate the causes with a careful medical evaluation.
Why is my poop green: What are
What is meant by Green Feces?
The green stools represent an alteration of the standard brown color of feces. This manifestation is frequently observed in the case of diarrhea. And in many conditions characterized by the accelerated transit of food through the intestine. The rapid passage of the ingested material does not allow the bile to be metabolized. Therefore the manure remains green. It assumes the pigmentation of the bile metabolite as if it had just come out of the gallbladder.
The bile is a dense substance of yellow-green color. Which is produced by the liver, stored in the gallbladder, and poured into the intestine. Where it aids digestion and the ‘ absorption of lipids food.

The stool color is a signal of the state of health not only of the digestive tract but also of the organs involved in the digestive process: liver, pancreas, and gallbladder (or gallbladder ).
Stool color: why is my poop green?
Understanding the composition of feces is a fundamental step also to understand the causes at the origin of their discoloration: The stool is made up of 75% water and the remainder of bilirubin, fats, proteins, undigested or indigestible food (this is the case with dietary fiber and cellulose ), bacteria, cells of the digestive tract, and mucus.
As a rule, the color of the stool is brownish brown, more or less dark. However, it can vary according to the digested food. This characteristic is mainly due to the presence of bile pigments escaped. From intestinal reabsorption and metabolized by the local flora. The natural color of the feces is due, primarily to bilirubin, a substance contained in bile, derived from the degradation of red blood cells. In the intestine, bilirubin is first transformed into urobilin, then into stercobilin by the intestinal bacterial flora: it is the latter substance that gives the stool its characteristic brown color.
It should be noted that bilirubin derives, in turn, from a precursor, called biliverdin, also present in the bile and, sometimes, in the feces, to which it gives a green color. This situation occurs when intestinal transit is so fast as to cause an incomplete transformation of biliverdin into bilirubin and derivatives. Therefore, green stools are a typical expression of diarrhea and of the conditions of a pathological and non-pathological nature (e.g., laxative abuse ) that cause it.
How should the colour of the stool be?
Before going into the specific problem of green feces, it will be appropriate to go into the subject of wastes and precisely the issue of their color. The feces of a healthy person are brown in color, which can have different spectra, a sign of a healthy body, and a successful digestive process. Before reaching the intestine, the feces have a color between yellow and green (due to bile). But subsequently, thanks to the last stage of processing due to the bacteria of the intestinal flora.
In general, changes in stool colour, even when they turn green, sign an unfinished digestive process, which must be thoroughly investigated if it is not a sporadic episode. But instead what has become the normality. The standard colour of the feces has been the subject of our in-depth guide. I invite you to read if you want to know the factors that affect our manure’s colour.
What are the most common causes of green stools?
When the stool is green, the most common causes can be basically three:
- the massive use of antibiotics in the last period could have altered the normal functioning of the bacterial flora. Antibiotics could, in fact, weaken it and therefore make the previous process that takes place in the intestine less intense, the one that transforms the stool from yellow/green to brown;
- a bacterial infection;
- a bad diet.
When the problem is with food
Often the production of green poop is due to problems related to the diet. That you are following and in particular to certain foods that you are taking. For example, many green leafy vegetables (especially if the color is very dark, such as in cabbage) contain enormous chlorophyll, which ends up finding itself in the stool, making it green. If we had consumed a lot of green leafy vegetables and greens in the days before green defecation, there is nothing to worry about.
It will, in fact, be a temporary problem, which will disappear as soon as we return to a regular diet. This is an event that absolutely must not cause concern, as it does not signal any malfunction of our body or our gastrointestinal system. If, on the other hand, we have observed a regular diet without particular excesses, then the appearance of green poop may be simply due to the stationing of waste inside the intestine.
When antibiotics are to blame
In other cases, the cause of green stools can be attributed to particularly prolonged antibiotic-based treatments, which may have been prescribed by the doctor to counteract a bacterial infection that is difficult to eradicate. In this case, however, antibiotics can also destroy a large part of the bacteria that make up our intestinal flora, reducing its population.

In this case, it is certainly advisable to contact the doctor who prescribed the treatment in question and point out that antibiotics, among the side effects, could have caused problems with the intestinal flora.
What parasitic and bacterial infections cause green stools?
The green feces can also be the result of infections that affect the intestinal tract, which may be either parasitic nature of bacterial in nature. Salmonella is a bacterium that has a brief incubation period. And can affect even after only 12 hours the ingestion of food or liquids that contained it. However, it hardly manifests itself exclusively with the presence of green feces. In fact, these are accompanied by abdominal pain, often excruciating, fever, vomiting, and feeling of general malaise.
