A young patient, let’s call him Chad, goes to the doctor. He complains of attacks of nausea from the moment he wakes up in the morning. Sometimes his belly hurts as well. It’s been happening, on and off, for years. He gets cold and shaky. At times, it will progress to full-fledged vomiting, uncontrollable with any medications. The nausea is unbearable. Sometimes, getting in a very hot shower will take the edge off the nausea, but not always. In many cases a trip to the emergency room is needed for rehydration and intravenous anti-nausea medications.
