Introduction
Green stool may be caused by bodily factors, such as indigestion or acute gastroenteritis, which affect digestive function and impair the adequate absorption of nutrients from food, leading to rapid excretion of undigested food. It could also result from recently consuming large amounts of vegetables containing green pigments; some of these pigments cannot be fully digested and absorbed, thus causing the stool to appear green.
Green stool may be due to bodily factors, or it could result from consuming a large amount of green vegetables in a short period.
1. Physiological factors
Green stool may occur if the individual has recently eaten a significant quantity of vegetables containing green pigments, such as spinach or chives. Since some of these pigments cannot be fully digested and absorbed, they may cause the stool to appear green. This is generally considered a normal physiological phenomenon.
2. Pathological factors
If accompanied by physical discomfort—such as indigestion caused by overeating or irregular eating habits, or acute gastroenteritis due to unhygienic food—the digestive function may be impaired. This can lead to inadequate absorption of nutrients and rapid expulsion of undigested food, resulting in green stool. It may also be accompanied by symptoms such as bloating, abdominal pain, nausea, vomiting, and diarrhea.
When green stool occurs along with discomfort symptoms, it is advisable to promptly visit a hospital for examination to determine the underlying cause and receive appropriate treatment.
