To evaluate the improvement of clinical symptoms and anxiety-depression in patients with functional constipation (FC) using warming acupuncture.Methods:A total of 70 patients with FC in Guang'anmen Hospital South District，China Academy of Chinese Medical Sciences from January 2017 to December 2017 were randomly divided into the observation group and the control group，with 35 cases in each group.The observation group was treated with warming acupuncture，while the control group was treated with conventional acupuncture.The constipation clinical symptom score，first defecation time，TCM syndrome score，SAS and SDS score were compared between the 2 groups before and after treatment.Results:The total effective rate was 96.00% in the observation group，and 68.00% in the control group，with statistically significant difference (P<0.05).After treatment，the weekly defection times，fecal character score，the difficulty in defecation of the 2 groups were improved.The TCM syndrome score，SAS and SDS score in the 2 groups were decreased than before treatment，with statistically significant difference (P<0.05).After treatment，the weekly defection times and fecal character score of the observation group were higher than the control group.TCM syndrome score，SAS and SDS score，first defecation time，and the difficulty in defecation in the observation group were significantly lower than those in the control group，with statistically significant difference (P<0.05).Conclusion:Warm acupuncture can regulate gastrointestinal movement，moisten the intestines and significantly improve the constipation and other clinical symptoms.Also，it has significant clinical effect on FC.
