Why might your stool be stringy green and smell of metallic iron?

Stringy green stool with a metallic iron smell could indicate the presence of undigested food, possibly due to a fast transit time through the intestines. The green color may arise from bile or certain foods, like leafy greens or food coloring. A metallic odor might suggest the presence of blood or iron supplements. If these symptoms persist, it's advisable to consult a healthcare professional for further evaluation.
