Morning sickness is a nauseous feeling that pregnant women experience during their first trimester of pregnancy. Nausea can also be accompanied by vomiting. Other names for morning sickness are nausea gravidarum, emesis gravidarum and nausea/vomiting of pregnancy are the other names for morning sickness which occur in around 80 percent of pregnant women.

Despite is the name, nausea does not only occur in the morning. It can occur at other times of the day. The cause of not clear although scientists believe that changes in hormones and are responsible.

The symptoms of morning sickness are terrible but it should not be a cause for concern unless it is extreme because it is a sign of healthy pregnancy.



There is a possible connection between morning sickness and loss of pregnancy due to impact on hormone production. Pregnancy occurs when a fertilized egg attaches to the uterine lining. When the body senses the fertilized egg in the uterus, it begins producing HCG (the hormone human chorionic gonadotropin) hormone. HCG has a link with nausea and vomiting thus morning sickness shows that the body is responding excellently to pregnancy by increasing levels of HCG. Women with hyperemesis gravidarum( severe morning sickness) have higher HCG levels. Women who are pregnant with more than one baby also have higher HCG levels. HCG helps with the proper and safe development of the fetus and reduces chances of miscarriage.

Nausea and vomiting during pregnancy also occur due to an increase in estrogen, another essential hormone during pregnancy. Morning sickness is an indicator that a woman is experiencing a normal increase of pregnancy hormones necessary for healthy pregnancy.


Research shows a strong correlation between reduced miscarriage risk and morning sickness. The risk of miscarriage is higher in the first trimester of pregnancy the same time when women begin experiencing morning sickness. Studies show that women who experience nausea during pregnancy reduce chances of miscarriage by 50 percent. The risk is even lower among women who experience morning sickness for more than half of the pregnancy. Surprisingly severe nausea lowers the risk of a miscarriage even further by up to 80 percent.

One of the explanations is that women who get the nauseous feeling during their pregnancy have more levels of essential hormones that help to protect them from harmful substances in their diet. The women also are careful in selecting the foods they eat.

It is common to use spices for killing potential bacteria in meat. Since spicy foods trigger morning sickness, many women avoid spices which are sensible in protecting the fetus as some of them contain toxins.

Women who experience morning sickness avoid or eat less of fried food, poultry, fish, meat, eggs, coffee and alcoholic beverages. Studies show that caffeine in coffee is dangerous for pregnancy. Meat or fish are not harmful but they have pathogens and parasites which do not die if there no proper cooking. Both are dangerous to a fetus in the first week of pregnancy. Immunity at this time is very to allow implanting of an embryo in the womb thus expectant moms are at more risk of attack from toxins and germs. Nausea makes women be choosy about their foods enhance their safety and that of the baby.


The placenta takes over the role of producing hormones necessary for fetus development. Hormone levels in the woman’s body reduce leaving those in the placenta to play more roles. A lower hormonal level in the body can cause morning sickness showing that the placenta is functioning well and ready to carry the pregnancy.

Morning sickness should not worry pregnant women as it is a sign of essential hormonal changes to support the growth of the fetus. They should end nausea unless and vomiting unless it is constant. Frequent visits to a doctor will help in determining if the morning sickness or normal or there is a cause for alarm.
