Question: My 71 year old mother went into the er with breathing difficulties, headache, weakness and light-headedness. They diagnosed her as having destabilized congestive heart failure due to onset of pneumonia. They put her on oxygen, Lasix, and antibiotic Levofloxacin. She was in the hospital for 3 days. On the 2nd day, her blood showed dropping hemoglobin level. Down to 8. They put her on a heavy iron pill that gives her terrible side effects. Her dosage was reduced to help with side effects. Two weeks later, her hemoglobin is still low. 7.5. She feels awful, weak, fatigued, aching and she can't eat. Her body doesn't seem to accept or digest food. She has lost weight 5lbs? and is under 90 lbs. She has always had weird non-specific auto-immune type issues. The doctors seem to ignore this. I believe the antibiotic may have caused her body to attack her own red blood cells, and may have also killed all gut bacteria, so she cannot eat or digest food. Have you ever heard of anything like this, or have you had some experience that makes this scenario ring any bells for you?
