My daughter is 32, she has been under a lot of stress taking finals as she studies to be an RN. She had strept throat but tried to keep going, was not sleeping but a few hours each night to push herself to study for finals, was not eating right. She had flu like symptoms of vomiting, weakness, then became mentally confused and at that time her husband took her to the ER. Her blood sugar level was 1300. After two days of treatment it is still too high at 487. Should this cause her complications in the future and what might those be?
