Functional vomiting (FV) is considered as recurrent, unexplained vomiting lacking an organic basis at least once per week and not cyclical. Although functional vomiting is a rare disorder and has been under-investigated, it has been increasingly recognized that it is a serious threat to people’s life quality. There have been many papers on how to treat functional vomiting, and agreements have been made that combined treatments on the base of improving nutrition status and maintaining spiritual support could be useful. We report the case of a young female with recurrent postprandial vomiting for one and a half years, who was diagnosed as functional vomiting. The treatment strategies were as follows: to have more meals a day but less food each time, to receive antidepressant, prokinetic agents and cognitive behavioral therapy. During the follow-up, the patient gets better after treatment, providing a vital evidence for further treatment.
