Causes of nausea during pregnancy The cause of nausea during pregnancy is not completely understood. However, it does appear to be linked to the production of the human chorionic gonadotropin (HCG) hormone. Commonly referred to as the pregnancy hormone, this is the hormone which the body begins to produce once the fertilized egg attaches to the uterine lining. Again, how it contributes to nausea is unknown, but because they both peak around the same time, they’re assumed to have a clear connection.
There are other theories as to what causes nausea during pregnancy, as well. Some other contributing factors might be:
- Estrogen, which is another hormone that rises during early pregnancy and could contribute to the queasiness.
- A sensitive stomach, which could be made worse while trying to adapt to the changes of pregnancy.
- Stress or fatigue, which is suggested to cause a physical reaction within the body, leading to nausea and vomiting.
