Why does nausea occur during pregnancy?

Nausea during pregnancy is a very common symptom, affecting around 80% of pregnant women! Nausea can occur at any time of the day, but is often more frequent on waking, hence the name "morning sickness".

One of the main causes of nausea is increased hormone levels, particularly human chorionic gonadotropin (hCG) and estrogen. These hormones are produced in large quantities by the placenta and can stimulate the central nervous system, leading to nausea.

In addition to these hormonal factors, other elements can contribute to this symptom. For example, the digestion of food can be slowed down, leading to a de facto accumulation of food (and causing nausea). Stress, fatigue and habit changes can also contribute to nausea.

It is important to consult a doctor if nausea s is accompanied by other symptoms such as frequent vomiting, significant weight loss or signs of dehydration , to avoid any risk to the baby's development.

When does nausea occur during pregnancy?

In mid-gestation

Nausea in mid-gestation can persist in some women, but tends to s'lessen compared to the beginning. At this stage, it can have several causes:

• Gastroesophageal reflux: acid reflux is more common in pregnant women due to the pressure exerted on the stomach by the growing uterus;
• Increased sensitivity to odors;
• Diet: pregnant women may be more likely to suffer from nausea if they eat high-fat, spicy or sweet foods;
• Stress: nausea can be exacerbated by stress, which is common at this time of life!

Nausea in mid-gestation can also be a symptom of pre-eclampsia, which requires immediate medical attention.

Nausea in late pregnancy

During this phase, they can be caused by the lack of space in the uterus, which compresses the stomach and leads to a more rapid feeling of satiety. It can also cause acid burn and reflux, which aggravate nausea.
