Overview

This trial is a randomized, double-blind, parallel placebo clinical trial, the purpose of which is to investigate whether the adjuvant therapy of using probiotics during the treatment of diabetic patients can decrease blood sugar levels significantly in comparison with placebo, and observe if the reduced lung function could be recovered in patients with type 2 diabetes (T2DM) and chronic obstructive pulmonary disease (COPD) simultaneously.
