Abstract Objective To study the effects of psychological disorder on the gastric function and quality of life of patients with dyspepsia. Methods For research group, 58 cases of patients with psychological disorder were selected from those admitted by the digestive system department of our hospital since October 2014 to December 2016, and other 58 cases of patients without psychological disorder were selected as regular group. Via careful observation, two groups of patients were compared for their scoring of quality of life, (including role emotion, viability, physiological function, role physical, society function, bodily pain, mental health, general health, et. al.), electrogastrogram before and after meal, water load test and SPECT gastric emptying test and other situation. Results In the case of various scoring of quality of life, patients in regular group were dramatically better than patients in research group, and the difference was statistically significant (P＜0.05). For the comparison of electrogastrogram before and after meal, the normal rhythm percentage of patients in research group was obviously lower than that of regular group (P＜0.05). The bradygastria rate and instability index of dominant frequency of research group were significantly higher than those of regular group (P＜0.05). For the comparison between water load test and SPECT gastric emptying test, the initial sensation quantity and maximum tolerance dose of patients in regular group were dramatically higher than those in research group, and the difference was statistically significant (P＜0.05). Conclusion The functional dyspepsia is closely related to psychological disorder, having side effects on quality of life and gastric motility function of patients to some extent.
