Abstract
Background/Aims: Functional dyspepsia (FD) overlapping with other gastrointestinal disorders are quite common. The characteristics of FD overlap in Chinese population with latest Rome IV criteria were unclear. This large-scale outpatient-based study assessed the characteristics of FD overlap in South China. Methods: Consecutive FD patients visited the Gastroenterology Clinic at 2 tertiary medical centers in Hangzhou, China who fulfilled the Rome IV criteria were enrolled. Complete questionnaires related to the gastrointestinal symptoms (Rome IV criteria), Reflux Disease Questionnaire, anxiety and depression, quality of sleep and life, and demographic information were collected. Results: < 0.001). Multivariate logistic regression showed that increasing age, female, low body mass index, history of gastroenteritis, anxiety, depression, and poor sleep quality were independent risk factors for FD overlap. Conclusions: FD overlap was quite common in China with high economic burden and poor quality of life, FD patients with history of gastroenteritis, anxiety, depression, and poor sleep quality were more likely to have overlap disorders. Awareness of the physical and psychosocial stressors in overlapping condition would help optimize the management of FD overlap in clinical practice.
