Fact or myth?
Myth: "Morning sickness is harmless and just part of pregnancy."
Fact: Although nausea is very common during pregnancy, it is considered a medical condition if it interferes with daily life or the ability to work. Those affected do not have to "just tough it out," but should receive support.
When there are more babies on the way: Understanding nausea
Nausea is often more pronounced in multiple pregnancies. The reason: the body produces more pregnancy hormones such as hCG and GDF15, which can promote nausea.
Did you know?
In a multiple pregnancy, the body forms more placental tissue than in a single pregnancy. This releases higher amounts of the messenger substance GDF15. GDF15 acts on centers in the brain that regulate nausea and appetite. The increased levels can cause morning sickness to occur more frequently or be more severe. This reaction is a natural consequence of the changed hormonal situation and is not a sign of illness.
Multiple pregnancy – special demands on the body
In a multiple pregnancy, more than one baby grows in the womb at the same time. This poses special challenges for the pregnant woman's body. In order to provide sufficient nourishment for all the children, the body produces larger amounts of pregnancy hormones. As a result, typical complaints such as nausea, fatigue, or circulatory problems may be more pronounced than in a single pregnancy.
The physical strain is also greater: the uterus grows faster, energy and nutrient requirements increase, and many changes occur earlier or more intensely. At the same time, multiple pregnancies are closely monitored by doctors to ensure the best possible health for mother and children.
Despite the additional demands, multiple pregnancies often go well. With sufficient attention to your own body and regular medical care, these special months can be experienced safely and consciously.
