A complete medical evaluation may be necessary for correct diagnosis and treatment. In cyclical vomiting the episodes start with severe vomiting which occur several times per hour and last less than 1 week with absence of nausea or vomiting between episodes. There may be abdominal pain, diarrhea, fever, dizziness, and sensitivity to light during vomiting episodes. Other possibilities are gastritis, GERD etc.If the symptoms are severe and persistent you may schedule your endoscopy at an earlier date. Contact your doctor. Keep me posted on how you are doing.
Take care and kind regards!
