Abstract: In recent years, research on the clinical phenotypes, new classifications, modified functional tests, biomarkers and management experience for patients with Gitelman syndrome (GS)has made a lot of progress in China. Based on evidence-based medicine, this consensus summarizes aspects related to GS, including clinical manifestations and classification, diagnosis, treatment strategies, and management of chronic complica-tions and comorbidity. This consensus provides an important reference for the diagnosis and treatment of GS.-
