Doctor, I've been feeling fatigue lately, and I'm always tired long after I've been asleep, so can you tell me why?
Hemolytic anemia may be the cause of fatigue, and hemolytic anemia is a disease that causes fatigue and weakness because there's not enough red blood cells to carry oxygen throughout the body.
