Identified hyperlink between diabetes and sleep issues
A examine of this kind can solely present affiliation and never causation, mentioned sleep specialist Dr. Raj Dasgupta, an assistant professor of medical medication on the Keck College of Drugs on the College of Southern California, who was not concerned within the analysis.
