<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing fatigue lately. I feel tired all the time, even after sleeping for long hours. Can you tell me what could be the reason behind this?  <response>: Hemolytic anemia could be the reason behind your fatigue. Its a condition where your body doesnt have enough red blood cells to carry oxygen throughout your body, leading to tiredness and weakness. Well need to run some tests to confirm the diagnosis.
