Nausea During Pregnancy.

Nausea during pregnancy is typically one of the most experienced and complained about symptoms that women report. Up to 70 percent of expectant mothers experience nausea at some point during early pregnancy. Not only is it known to be one of the early signs of pregnancy, but it is a symptom which is common throughout the first trimester, and sometimes even longer. While nausea is definitely an uncomfortable feeling, the good news is that it is not harmful to you or your baby and it is often perceived as an indication of a healthy pregnancy.  Nausea is a key part of the common concern referred to as morning sickness.

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.

When to expect nausea during pregnancy Nausea during pregnancy typically starts within four to eight weeks of gestation and is expected to subside between 13 and 14 weeks. However it can start earlier and can last longer. Not every woman will experience nausea the entire duration of the first trimester. It could last only a couple of weeks or come and go throughout the first few months. Many refer to nausea during pregnancy as morning sickness, leading women to believe they will only experience nausea in the mornings. In fact, research shows that “morning sickness” actually occurs more often throughout the entire day than just in the early hours.
