Abstract: Objective To analyze one case of severe diarrhea induced by semaglutide injection and to provide clinical physicians with references for its rational use. Methods Based on findings of research currently available, the diagnostic and therapeutic process, risk factors, potential mechanisms and treatment strategies related to a patient with severe diarrhea that was considered to have been caused by semaglutide injection were analyzed. Results During hospitalization, the patient experienced severe diarrhea after receiving two doses of semaglutide injection (0.5 mg). The symptoms were alleviated following symptomatic treatment. After discharge, severe diarrhea recurred when the patient was readministered with semaglutide injection (0.5 mg). The symptoms abated after discontinuation of medication. Conclusion Clinicians should initiate semaglutide injection at a low dose as instructed. Particular attention should be paid to such adverse reactions as diarrhea induced by semaglutide injection. Prompt interventions are warranted once such adverse events occur.
