my mother who is 73 yrs old was septic last week with infection in bloodstream. off antibiotics and out of hospital one week today and she is very weak. blood pressure is 102 and 62, heart rate is 104 yesterday and today. Blood pressure and heart were good before that. could this just be the anemia?
While this could be from anemia it could also signal deny Chat Doctor.  You should let her doctor know about this
