This study published in DiabetesCare suggests that higher consumption of sugar-sweetened cola (≥5 servings/week) is associated with elevated gestational diabetes mellitus (GDM) risk (22% increase compared to those who had <1 a month).

Gestational diabetes mellitus (GDM) is one of the most common pregnancy complications. Women with GDM are at increased risk for complications and illness during pregnancy and delivery, as well as post-pregnancy type 2 diabetes. Children of mothers with GDM are at increased risk for obesity, glucose intolerance, and early onset diabetes.
