Patient's question:
I am a senior high school student and have severe iron deficiency anemia. I only have 1.8 grams of iron. Recently, I noticed that my stool is black. Is it because of internal bleeding that makes my stool black? Then, is it because of internal bleeding that leads to iron loss? But I don't have any painful areas in my stomach.Doctor's answer:
Analysis of the condition:Dark stools may be due to several factors. One is upper gastrointestinal bleeding, and the other is the consumption of foods containing melanin or pig blood, such as some patients with gastric ulcers who have black stools. Additionally, ingesting foods with melanin can also cause this. However, the specifics you mentioned were not clearly stated.
Suggestions:
I’m not sure if you’re referring to vitamin B12. If so, this medication does not cause black stools. It is recommended to have a stool test done at the hospital for peace of mind.
