The excretion of dark green is too much green food intake, taking spirulina-type health care products factors lead to. Some people have intestinal inflammation, indigestion, and green vegetables contain chlorophyll, which will not be absorbed by the body and will be excreted as is. When too much green food is consumed, chlorophyll will accumulate in the intestines in large quantities and be excreted along with the feces, which is dark green in color. Some people use health supplements to improve their immunity, especially spirulina, which can cause green stools without abdominal pain or diarrhea. If the color of feces appears dark green and there is bloating and diarrhea at the same time, you should be alert to enteritis and indigestion. Enteritis and indigestion will lead to a relative reduction in the retention time of food residues in the intestine, and bilirubin will not be able to combine with alkaline substances, and bilirubin will be oxidized by acidic substances to bilirubin, resulting in the formation of dark green feces.
