, also known as nausea
and nausea gravidarum
, is very common during pregnancy
. Morning sickness affects mostly pregnant women: around 60-80 percent
Nausea and vomiting are so called as morning sickness due to the fact that most women suffer from it at early hours of the day. Morning sickness can actually occur at any time during the day.
For some women it can be worst in the morning and then reduces as the day progresses. A headache often arises with morning sickness; along with it a feeling of dizziness and exhaustion as well.
The nausea can induce actual vomiting but not severe enough to cause any metabolic imbalance. In acute conditions, vomiting may cause dehydration, loss of weight and can even reduce hydrogen ions concentration of the arterial blood plasma. In addition, a decrease in hydrogen ions causes the pH of blood to exceed 7.45, hence making the blood slightly alkaline. Also the concentration of potassium ions in the blood may decrease. These conditions are rare among pregnant women.
Morning sickness can really dampen your excitement about being pregnant however be assured that it does not hurt the baby in anyway unless the woman loses weight such as with severe vomiting.
Fortunately you can do something against it. And you can start today.
The amount of morning sickness
, though, during one pregnancy does not account for or predict how someone will feel during future pregnancies.
However, morning sickness in itself is not bad, it is thought to be an evolved trait that helps to protect the fetus against toxins ingested by the mother. Usually pregnant women experience nausea when they are in the vicinity to the smell or taste of food that might contain toxins which then could be harmful to the fetus even though harmless to the mother, thus causing a revulsion. Therefore morning sickness can be seen as a defense mechanism developed to protect the baby. Together with the baby, the mother also is protected.
This is explained according to scientific theories. The fetus developing in the mother's womb have different tissues and cell from that of the mother, therefore in order to reduce the risk that the mother's body reject their own offspring's tissues, the immune systems of the pregnant women are suppressed. In this way, nausea and vomiting acts as a defense mechanism for the baby and mother health
At around 18th weeks, the fetus is most vulnerable to toxins, hence the peak time for a women to suffer from morning sickness is more susceptible around the third month.
Besides, it is thought that pregnant women who do not suffer from morning sickness
sometimes undergo miscarriage or may even give birth to a handicapped baby. It is assumed that this is so because those women are prone to ingest toxins food substances that are injurious to the baby.
Also taking drugs to prevent or reduce morning sickness may have side effects such as baby born with birth defects or miscarriage of the baby is likely to occur.
