L’objectif n’est pas de boire plus que de raison mais de faire attention à sa consommation en eau, notamment si l’on a pas l’habitude de boire beaucoup.

What role does water play in the body?

The human body is made up mostly of water. The proportion of water varies depending on age and the individual.

Water plays a vital role in our body. It helps to transport nutrients to cells, eliminate waste and maintain the body at the right temperature.

The body is not able to produce sufficient water, so it is necessary to obtain it through food and to drink water in addition.

What are the water requirements during pregnancy?

During pregnancy, a woman's body undergoes many physiological changes, including significant changes in fluid balance.

Water content during pregnancy increases considerably, by an average of 6 to 8 litres. This water is found in:

The amniotic fluid,
The foetus (made up mostly of water)
The placenta,
Blood volume, which increases by nearly 50%.

It is therefore important to stay well hydrated in order to feel your best.

Pregnant women who experience vomiting lose significant amounts of fluid and should pay particular attention to staying hydrated.

Pregnant women are advised to drink between 1.5 and 2 litres of water per day.

How to stay well hydrated during pregnancy?

Pendant la grossesse, il est important d’avoir un bon apport hydrique. On trouve l’eau à travers l’alimentation et les boissons.

Du point de vue de l’alimentation, la femme enceinte doit conserver une alimentation équilibrée, consommer de nombreux fruits et légumes et éviter les produits trop gras, sucrés et transformés.

Côté boisson, il faut privilégier l’eau, les tisanes et éviter les boissons sucrées.

Pour les mamans qui n’ont pas l’habitude de boire suffisamment, quelques astuces :

Pensez aux soupes et bouillons : Nous avons un bouillon d'os déjà prêt pour vous, Mama poule, dont une portion de 240 ml contient près de 6g de collagène naturel, directement assimilable par le corps.
Prenez une boisson chaude le matin et l’après-midi lors des pauses, comme une tisane grossesse.
Vous pouvez envisager les électrolytes, mais on choisit toujours une vitamine pendant la grossesse avec précaution en s'assurant qu'elle soit bien compatible.
Ayez toujours une bouteille d'eau avec vous.

Which water should I choose during pregnancy?

Tap water is safe to drink in France.

It is preferable for pregnant women to drink low-mineral waters. These waters, particularly if slightly acidic, may also be appreciated in cases of nausea and heartburn.

In cases of constipation, you may wish to turn to waters rich in magnesium.

You can also drink herbal teas to keep hydrated and as a treat. Do be careful to choose a pregnancy-safe herbal tea, such as our Sweet Mama, as certain plants are not recommended during pregnancy.

To conclude

During pregnancy, the mother needs to consume between 1.5 l and 2 l of water per day.

A good water intake will help the pregnant mother to feel well and avoid certain pregnancy discomforts.
