Tonight, 20 minutes after dinner, the patient experienced a sudden onset of abdominal pain with nausea and regurgitated the majority of her meal; the nausea has persisted. The patient has not had a bowel movement in 3 days. She has a history of type 1 diabetes which was diagnosed at age 12; it has been well managed with a strict insulin regimen delivered by an insulin pump.
