My daughter is 17 years old, and her BP is 85 over 73 with heart rate of 100.  Should I take her to an emergency room?  She has a history of severe anemia that required blood transfusion that resolved.  She has chronic abdominal pain, and has been a bit worse the last few days.
Hello! Welcome on Chat Doctor! Regarding your concern, I would explain that in case your daughter experiences such a low blood pressure for the first time and can not tolerate such conditions (she feels extremely exhausted and is not able to perform her daily physical activity), then you should take her to the nearest ER service for a timely fluid HY Chat Doctor.  It is necessary to investigate the real nature of her chronic anemia (hemolysis, a chronic inflammatory disease, etc.) as it may explain the reason of her chronic abdominal pain (visceral organs' enlargement, etc.) Several lab tests should be done:- complete blood count,- PCR & ESR,- thyroid hormones level,- liver and renal function tests,- abdominal ultrasound,- fasting blood glucose,- hemoglobin electrophoresis, etc. You should discuss with her attending doctor on the above-mentioned issues. Hope to have been helpful to you! Kind regards,
