Cyclic Vomiting

The novel corona virus disease (COVID-19) has caused a great pandemic since the end of 2019. A variety of symptoms has been identified for this disease. In this case series we report 5 patients in different age groups who presented with cyclic vomiting as a late complication of COVID-19. All patients have gone through complete diagnostic process for cyclic vomiting syndrome (CVS) including endoscopy. However, they all showed normal findings. The diagnosis of cyclic vomiting syndrome was made based on the symptoms and normal endoscopic and laboratory findings. We treated all of the patients applying the guideline we previously published regarding treatment of CVS patients. According to the results of the present study, CVS might be a late complication of COVID-19 infection. So, it is necessary for physicians to consider it as a differential diagnosis in patients with recent COVID-19 infection and to be aware of its management in each phase.
