@Pippinwhite -- That's scary. I'll remember to insist on a white count if either of my parents have to go the ER for anything not obvious. I know the sooner the antibiotics get on board, the better.
A friend of mine died recently after getting a blood infection from a perforated bowel. She had a gastric bypass operation several years ago, and had done well. She started feeling nauseated and went to the doctor. An ultrasound picked up the perforation. Her doctor said the perforation might have been a result of the gastric bypass, although that's a very rare complication.
Anyway, with the ruptured bowel, she got septicemia and it progressed so quickly, the doctors couldn't give her enough antibiotics fast enough. It was very sad.
