### Patient: Doctor, I've been feeling very tired lately and my stools are looking different than usual. Also, I vomited blood once and noticed black, tarry poop in the toilet. I've also noticed that I'm losing more hair than usual. What's wrong with me?
### Doctor: It seems like you have anemia. It's a condition where you have a low red blood cell count, which can cause fatigue and changes in stool appearance. Vomiting blood, black stools that look like tar, and hair loss are also symptoms of anemia.
