Question
Why do adults sometimes have blue-green stools?
Answer
Based on the described situation, changes in stool color may be related to dietary factors. Blue-green stools might be caused by the incomplete digestion of vegetables, leading to the residue of their pigments. This condition is more common in individuals with weaker digestive functions, who may more frequently excrete food residue. As long as there are no other abnormal symptoms, these situations are usually considered normal. Wishing you good health!
