Dana is a 29 y/o marketing executive who woke up one winter morning “feeling sick.” She told her husband, “I feel tired, nauseated, and have mild stomach cramps.” It wasn’t long afterwards, she suddenly experienced the onset of vomiting, and diarrhea. Her husband encouraged her to drink liquids, but it only caused her to vomit more. The miserable morning led to dehydration, and by early afternoon she was receiving intravenous fluids in the Emergency Department of her local hospital.
