Nausea in Pregnancy

Nausea that affect many women during the first trimester of pregnancy would it simply the result of unusual delicacy of smell? This is the thesis defended by two gynecologists from Stanford University in California, including a book on nausea and vomiting is out, probably a durable reference on the issue.

After having reviewed all published articles on nausea in pregnancy and conducted their own research, the authors found that most women who experience nausea during pregnancy are unable to bear the smell usually regarded as pleasant as odors cooking or perfume. Researchers believe these "emanations" are the almost unique trigger nausea.

A strong argument to support this thesis. Some women are carrying a genetic disorder infertility and loss of smell. With appropriate treatment, these women can access pregnancy ... and be spared the nausea.

What Causes Nausea During Pregnancy

The common link between pregnancy, nausea and smell could be represented by estrogens, female sex hormones. These hormones increase when the woman is pregnant and are essential for maintaining pregnancy. It is also known that estrogen can cause nausea and this symptom is also one of the adverse reactions of conventional oral contraceptives most heavily dosed.

The presence of nausea and could indirectly reflect the fact that the pregnancy is progressing normally, the authors note. Some studies seem to indicate that miscarriages are rarer in women suffering from nausea.

Thus, according to the authors, estrogens would empower a hypersensitive olfactory, responsible, among those most sensitive, nausea, without the connection between the two phenomena is still unclear. Responsibility of estrogens is supported by the fact that, even outside of pregnancy, women are three to four times more likely than men to nausea.

Almost all women (98%) experienced at one time or another nausea in pregnancy, say the authors, based on investigations already published.
