The color of healthy adults is brown. This is due to the presence of sterocilin in human feces. This is one of the final pigment exchange products.
The color of feces is affected by the nature of food, as well as the intake of individual medicines. Stain stool with some pathological conditions has a special diagnostic value.
So, when the biliary tract becomes obstructed( clogged), the color of the stool becomes greyish-white, clayey( acholic).The condition can be triggered by the presence of a stone or the development of a tumor that causes a general compression. In addition, such a color of stool is characteristic for a sharp disorder of the hepatic function, which leads to a violation in the release of bilirubin.
When a bleeding occurs in the lower parts of the rectum or large intestine, as well as hemorrhoids, the feces become red. Often in such cases feces are characteristic for bloody impurities.
Black color stool, combined with a liquid-mushy or liquid consistency, appears against the background of bleeding in the upper gastrointestinal tract. This may be due to the formation of hydrochloric acid hematin.
With development of cholera, stools appear in the form of "rice broth", with typhoid fever - in the form of pea soup.
Green stools often indicate various gastrointestinal diseases. Often stools have this color in pathologies in the small intestine, dysbacteriosis, as well as with prolonged treatment with antibiotic drugs. In addition to color, the smell of bowel movements also changes. He becomes very unpleasant and putrid. Green coloration is caused by a high content of deceased leukocytes, accumulating in the intestine against the background of the inflammatory process.
Dysbacteriosis provokes irregularities in the normal digestion of food, which in turn causes fermentation or decay and the formation of substances that affect the color of feces. In addition, green stain color is characteristic for the development of a number of intestinal infections, including dysentery. Along with this, patients have typical signs of such diseases: fever, vomiting, tenderness in the abdomen of various intensity, general weakness, nausea.
Another reason for staining the stool in green is the development of bleeding in various parts of the intestine or stomach. It can be caused by an oncological disease or complications of a peptic ulcer. In such cases, stain color is associated with the oxidation of iron, which is part of the red blood cells.
The frequent cause of the appearance of green feces are diseases of the blood and liver. Against the background of the pathological state, active decay of erythrocytes takes place, and bilirubin is formed in large numbers from hemoglobin. This pigment, entering the intestine, can give the feces a green or dark brown color.
When staining feces in an uncharacteristic for a normal, healthy condition, the hue should be consulted by a specialist. In this case, a mandatory examination, including a laboratory test, should be performed.
As mentioned above, the staining of feces has a special diagnostic value for different conditions of a person. It should be noted that the color of feces during pregnancy indicates the quality of the liver. It is during this period that the body experiences increased stresses. The color, odor, and the consistency of the feces may change during the prenatal period. Often this is due to the use of multivitamin complexes, which, as a rule, contain iron. However, during the entire period of gestation, control over the state of the assays is necessary. This applies not only to feces, but also blood, and urine.
