[Obesity and its consequences for pregnant women].

Obesity is an increasingly common disease complicating the course of pregnancy, labour and post-birth recovery. Therefore, conscious decision about conception seems to be vital as maternal obesity can also influence the baby's birth weight and health. The cascade of complications that may occur in the perinatal period in women with excessive BMI has a negative impact on the mother and the child, what translates directly into significant problems--of obstetric and gynaecological, pediatric and often also physiotherapeutic nature.
