What causes dark green stool?

If you find that your stool is dark green during bowel movement, it may be caused by indigestion and some intestinal dysfunction. However, if some patients undergoing abdominal surgery use antibiotics extensively, the stool may also be green watery.

1 Green, watery or pasty, with a sour smell and lots of foam. It is often seen in diseases such as indigestion and intestinal dysfunction. If the green stool is mixed with pus, it is a sign of acute enteritis or bacillary dysentery. Patients who have undergone major abdominal surgery or received extensive antibiotic treatment, if they suddenly have green watery stools with a fishy odor and grayish-white flaky, translucent, egg-blue pseudomembranes, may have Staphylococcus aureus enteritis. In addition, eating a lot of foods containing chlorophyll or excessive acidity in the intestines can also turn the stool green. ?

2 Light red stool like meat washing water. This type of stool is most common in the summer due to eating certain pickled foods contaminated by halophilic bacteria. Common diarrhea is caused by Salmonella infection. ?

3 Bright red is common in lower gastrointestinal bleeding. If the outer layer is sticky with blood in a small amount and is accompanied by severe pain, which disappears after defecation, it is anal fissure. If the blood is bright red, in varying amounts or in the form of blood clots, attached to the outer layer of the stool and not mixed with the stool, and the blood or blood clots can be washed away with water, there may be internal hemorrhoid bleeding. Another characteristic of hemorrhoidal bleeding is that a small amount of blood often drips or spurts out after defecation and stops on its own after a while. If the blood is bright red and mixed with the stool, it may be caused by intestinal polyps or rectal cancer or colon cancer. The bloody stool of rectal cancer is often mixed with erosive tissue. The bloody stools of colon cancer are characterized by fresh blood in small amounts accompanied by large amounts of mucus or pus. ?

4 Dark red is dark red because the feces are evenly mixed with blood, also known as jam color. Common in amoebic dysentery, colon polyps and colon tumors. In addition, certain special diseases, such as thrombocytopenic purpura, aplastic anemia, leukemia, hemorrhagic fever, etc., can also cause blood in the stool due to coagulation disorder. This blood in the stool is generally dark red, sometimes bright red, and is often accompanied by bleeding in the skin or other organs. Another situation is that normal people who consume excessive amounts of coffee, chocolate, cocoa, cherries, mulberries, etc. may also have dark red stools.
