Obesity is a public health phenomenon affecting more than 17% of women in France, and more than 20% of men and women in Champagne-Ardenne.

Obese women are more likely to have an unplanned pregnancy, whereas these pregnancies are more at risk than women of normal weight and should be planned or considered after weight loss. These women are also often less well followed in terms of gynecology and especially on contraception.

More and more patients are opting for bariatric surgery. However, bariatric surgery is not trivial. Indeed, the important loss of weight expected is at risk of nutritional deficiencies. In addition, a large number of patients are still obese during the months following surgery. This is why pregnancy is theoretically contraindicated within 12 or 18 months postoperatively.

Women with bariatric surgery must have been properly informed of these risks so that they can choose a contraceptive method, and that can be adapted to both their risk factors and the surgical technique performed.

The purpose of this study is to describe contraception in obese women who have undergone bariatric surgery in Champagne-Ardenne.
