Scientist at US compared results of 248 overweight women on pills who became pregnant with 533 non pregnant women using same method of birth control.

This higher risk of pregnancy translates into a higher number of Obesity-related complications of pregnancy, which range from Gestational diabetes and high blood pressure to Caesarean delivery. Obesity is a health hazard but now it is also linked with unplanned pregnancy. “The more a person weighs, the higher their basal metabolic rate, which can shorten the duration of the medication’s effectiveness,” said Dr Holt.
