The U.S. Food and Drug Administration (FDA) has issued an alert for patients using diabetes devices, including continuous glucose monitors (CGMs), insulin pumps, and automated insulin dosing systems. The alert warns that some users are not receiving or hearing critical alerts from their smartphones. Missing these alerts can lead to severe health risks, such as hypoglycemia, hyperglycemia, diabetic ketoacidosis, and even death. These alerts are essential for monitoring and managing blood sugar levels effectively, but misconfigurations in smartphone settings can prevent users from receiving them.
