Cough hypersensitivity in patients with metabolic syndrome: A clinical finding and its possible mechanisms

To investigate the changes of cough sensitivity in patients with metabolic syndrome and its possible mechanisms. Increased capsaicin cough sensitivity in MetS patients is closely related to sleep apnea and gastroesophageal reflux. For patients in MetS patients without OSAHS, gastroesophageal reflux is an important factor for increased capsaicin cough sensitivity.
