2. Vomiting Phase
Once the prodrome phase is over, the patient will then move onto the vomiting phase. The term is quite self-explanatory as the patient will begin retching and vomiting, as well as still feeling nauseous. This phase will often last for around half an hour while, in some cases, it can last for up 10 days. The patient will usually vomit 5 or 6 times every hour. This phase can be quite debilitating for the patient and they may be unable to move for the duration. They might also experience other symptoms including abdominal pain, fever, headaches, light sensitivity, drowsiness, diarrhea, paleness, excess saliva, and drooling.
