Pregnancy is a miracle for most people, both women and men. Women usually think that is great, until they start to experience morning sickness calls to the bathroom. Well, the condition is called morning sickness, although some women feel nauseous and/or vomit throughout the day. Don’t be alarmed by this condition, it’s only transient. By the end of the third month most women don’t feel a hint of nausea any more.
What Causes Nausea in Pregnancy
Scientists haven’t been able to identify an exact reason that causes morning sickness in pregnant women. More or less, everything they say is a theory so far, based upon the observation of thousands of pregnant women over the years of research. However, some causes are very likely to be responsible for the nausea and vomiting in pregnancy. These potential reasons include hormonal changes, sensitivity to smell, genetic predisposition to nausea or even some vitamin deficiency.
Hormones that are considered causes of morning sickness are HCG (human Chorionic gonadotropin), progesterone and estrogen. HCG is one of the hormones commonly believed to provoke morning nausea in pregnant women. After the conception, embryo is responsible for the production of this hormone, while in the later stages of pregnancy placenta takes that role. Its main role is to maintain the production of another important pregnancy hormone – progesterone. Both of mentioned hormones can lead to morning sickness in pregnant women. HCG has stomach upset as one of the known side effects, and progesterone might relax stomach and intestines so much that they produce excess acids. This acid is also one of probable causes of nausea in pregnancy.
Estrogen rise in early pregnancy can also be acceptable explanation for nausea and vomiting.
Because of the heightened level of estrogen or some other factors, many women may have increased sense of smell or stomach sensitivity in early pregnancy. Pregnant women can be so sensitive to smell to vomit even after sensing something common and usually inoffensive.
There is also some inheritance involved in this matter, and some women may be genetically predisposed to react to stress by nausea and vomiting.
Lack of vitamin B6 or some other vitamins may sometimes provoke vomiting in pregnancy. Supplemental vitamin B6 or multivitamins may be helpful in some cases, but sometimes they simply don’t work. Because of that, it is not clear what exactly vitamins and nausea have in common.
Good nutrition in pregnancy is vitally important, for both expecting mother and her baby. Some say that finding the right food may ease your morning sickness and make it disappear. Furthermore, good nutrition before and during the pregnancy may prevent neural tube defects, pre-eclampsia or gestational diabetes.
