By Lydia Davis Emerging evidence shows that variability in your A1C level may put you at a higher risk of stroke and heart disease. A recent study revealed that variability in an individual’s A1C levels could be associated with their risk for developing diabetes-related complications, such as heart disease. The study looked at the electronic health record data of almost 30,000 people with type 2 diabetes from 2013 to 2018 in southeast Louisiana. It included people who had at least four A1C measurements within two years of their diabetes diagnosis and no heart-related complications within that two-year period or the year before diagnosis. The sample’s demographics were 59% white and 41% African American.
