Patient's question:
I am a senior high school student and have severe iron deficiency anemia. I only have 1.8 grams of iron content. Recently, I noticed that my stool is black. Is it because of internal bleeding that my stool is 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, eating foods with melanin can also cause this. However, the specific situation you mentioned isn't clear.
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.
