High dietary ingestion of fast foods before pregnancy may make gestational diabetes more likely to occur in women during pregnancy.

​This study aimed to determine the role high pre-pregnancy consumption of fast foods play in the development of gestational diabetes. Researchers compared the fondness for fast foods before pregnancy with the rate of occurrence of gestation diabetes in a study population comprising of over 3,000 women who had never been diagnosed with diabetes or gestational diabetes. 

Researchers observed that a surge in the risk of gestation diabetes was associated with frequent ingestion of fast foods before pregnancy. This study points out that fondness for fast foods may increase a woman's chances of developing gestational diabetes.
