Why is a pregnant woman's stool green after taking blood-nourishing medication?

It is usually normal and not a cause for concern if a pregnant woman experiences green-colored stools after taking blood-nourishing medications. This phenomenon is primarily due to the iron content commonly found in such medications. Iron combines with sulfides in the intestines to form ferrous sulfide, a compound with a dark green or black color that can change the color of the stool. This change typically occurs during medication use and will generally return to normal gradually after discontinuation of the drug. To ensure the health of the pregnant woman, it is recommended to monitor any physical reactions while taking blood-nourishing medications and to consult a doctor promptly if any discomfort occurs. Additionally, pregnant women can support blood replenishment through dietary choices, such as consuming moderate amounts of iron-rich foods like lean meat, eggs, seaweed, and black fungus. Maintaining a balanced diet and increasing intake of fresh fruits and vegetables can also help improve anemia. If needed, please consult a qualified physician or pharmacist.
