Ozempic in Pregnancy: Diabetes, Not Drug, Linked to Early Births?

The reason you're taking Ozempic or Wegovy matters during pregnancy, with underlying diabetes potentially posing a greater risk than the medication itself. This study challenges the previously held, often generalized, assumption that GLP-1 medications alone are responsible for pregnancy complications.

Transient Cognitive Vulnerability After Hypoglycemia in Adults With Type 1 Diabetes: Evidence From Continuous Glucose Monitoring and Cognitive Ecologic Momentary Assessment

Hypoglycemia was associated with a transient period of cognitive vulnerability largely confined to the hour after an event, with little evidence of delayed effects. Findings support avoiding or exercising caution during cognitively demanding tasks for up to an hour after a hypoglycemic event.
