Nausea and vomiting, if it's occurring during a woman's first pregnancy, is greeted by most women with mixed feelings. It verifies her pregnant condition. The self administered pregnancy test gave correct results. She is definitely in a "family way." This can be either a happy or a sad moment, depending upon the woman's circumstances. For most women it's a proud moment that they excitedly share with friends and family. The excitement over this physical confirmation of her condition overcomes the minor discomforts of the nausea. She basks in the excitement and joy of her friends and family who share her excitement while thinking back to the joyful days of their own experience.

It doesn't take long, however, before the initial excitement of the mother to be and of her friends wears off. The nausea has done its job of notification, and physically uncomfortable morning sickness events no longer carry any social benefit. The mother to be begins her impatient wait for the nausea and morning sickness to become a memory.

Usually, morning sickness and its accompanying nausea end at the cusp between the first and second trimesters of the pregnancy. Most women find that it ends during the twelfth week, although for some women, the nausea continues up until the sixteenth week.

It's important to remember that these numbers are simply statistical averages based upon the study of a large population of pregnant women. Many women see symptoms cease abruptly near the start of the fourth month, while others find that the symptoms continue with decreasing intensity until near the end of the pregnancy. A statistically small number of women never experience any nausea and vomiting whatsoever. Interestingly, many women report that during their subsequent pregnancies, the nausea and morning sickness was quite difference. Some who had a bad time with nausea during the first pregnancy, enjoyed milder symptoms during the next one. Some other women had the opposite experience.

The nausea associated with morning sickness ends when the changes to the mother's body that causes nausea, end. It has been difficult to isolate the specific changes to the mother's body that are responsible for nausea and morning sickness, but several conditions are suspected as major contributors. Rapid changes in hormonal balance, heightened sensitivity to certain foods, and an enhanced sense of smell with increased sensitivity to certain odors are a few. Fortunately, the symptoms will eventually pass. In the meantime, when it seems they will last forever, physicians can prescribe medicines that alleviate the discomfort from most symptoms. Morning sickness, for most mothers to be, is a simple annoyance that they must bear to realize the joyful experience of the coming birth.

If you happen to fall into the small minority of expectant mothers who experience frequent and severe vomiting, or if these symptoms of morning sickness continue into the second trimester, you should see your obstetrician as there may be a more serious problem that needs attention. In most cases, although annoying to the mother, normal vomiting and nausea have no ill effects upon the baby. Severe and chronic nausea, however, can lead to poor nutrition and dehydration, both of which can affect the baby's overall health. If you cannot keep down fluids or food for a period of more than 24 hours, seek medical treatment.

These severe nausea and vomiting symptoms are rarely encountered, and affect around three women in a thousand. For most mothers in waiting, morning sickness, nausea, and vomiting are a mild annoyance that they accept as part of the rite of passage into the joys of motherhood.
