Morning sickness, also called nausea gravidarum, nausea, vomiting of pregnancy (emesis gravidarum or NVP), or pregnancy sickness is a condition that affects more than half of all pregnant women. Sometimes symptoms are present in the early hours of the morning and reduce as the day progresses. However, in spite of its common name, it can occur at any time of the day. For most women it may stop around the 12th week of pregnancy.
Related to increased estrogen levels, a similar form of nausea is also seen in some women who use hormonal contraception or hormone replacement therapy. The nausea can be mild or induce actual vomiting, however, not severe enough to cause metabolic derangement. In more severe cases, vomiting may cause dehydration, weight loss, alkalosis and hypokalemia. This condition is known as hyperemesis gravidarum and occurs in about 1% of all pregnancies. Nausea and vomiting can be one of the first signs of pregnancy and usually begins around the 6th week of pregnancy (counting gestational age from 14 days before conception).

Famous quotes containing the words morning and/or sickness:
“It seems only yesterday that we saw
The movie with the cows in it
And turned to one at your side, who burped
As morning saw a new garnet-and-pea-green order propose
Itself out of the endless bathos, like science-fiction lumps.”
—John Ashbery (b. 1927)
“The sickness of our times for me has been just this damn thing that everything has been getting smaller and smaller and less and less important, that the romantic spirit has dried up, that there is no shame today.... We’re all getting so mean and small and petty and ridiculous, and we all live under the threat of extermination.”
—Norman Mailer (b. 1923)
