La prise de poids est à voir au cas par cas. Ne vous fixez pas des objectifs inatteignables. Ne pas prendre de poids peut être très dangereux pour vous et votre enfant.

What is the ideal weight gain during pregnancy?

According to the National Nutrition and Health Programme (PNNS) published by the French health authorities, weight gain should average 12 kilograms during pregnancy, corresponding to roughly 1 kg per month during the first six months and 2 kg per month during the last trimester.

This weight gain reflects both the development of the elements involved in conception (the foetus, but also the placenta and amniotic fluid) and the adaptation of the maternal body to pregnancy (increased blood volume, as well as breast and uterine development). This weight gain is therefore necessary to carry the pregnancy in the best possible conditions — for both the baby and the mother!

Parmi le poids que vous prenez pendant la grossesse, il y a [1] :

~3 kg of fluids

~3–3.6 kg from your baby

~0.5kg of placenta

~1kg of uterus

~3 to 5 kg of reserves

Weight gain to be assessed on a case-by-case basis

This ideal weight gain during pregnancy should take into account your Body Mass Index. Indeed, the higher your Body Mass Index, the lower your weight gain should be.

It is therefore important to discuss this with your doctor. Based on your BMI and your personal history, you will jointly define the weight gain target and the steps to take to achieve it.

What is mummyrexia?

Attention à une nouvelle mode véhiculée par certains « people », relayée abondamment par la presse et les réseaux sociaux, appelée « mummyrexie » (contraction de « mummy » et d’ « anorexie ») destinée à garder quoi qu’il en coûte la ligne, voire ne pas prendre un gramme pendant la grossesse.

Comment cela se traduit-il ? Par une privation alimentaire volontaire associée à une hyperactivité physique. Sport et grossesse sont toutefois recommandés, mais dans des limites raisonnables.

Ce sont des symptômes que l’on retrouve dans l’anorexie mentale. Les dangers sont importants tant pour la mère que pour son bébé, allant de carences multiples à l’accouchement prématuré.
