what does morning sickness feel like
Having nausea or vomiting in the first trimester of gestation reduces the risk of miscarriage by more than 50%.
Four out of five women suffer from nausea or vomiting during pregnancy. Often very poorly experienced, and sometimes requiring hospitalization (1% of cases), these symptoms are not necessarily a worrying sign, notwithstanding the handicap that they represent the daily life of the future mother.
According to a study conducted by the American National Institutes of Health (NIH), they would be a good sign as they are accompanied by a reduction in the risk of miscarriage during the first trimester of pregnancy, which reaches 55% when there is nausea and 81% if accompanied by vomiting!
Two years ago, Canadian researchers had already published an analysis of this in the journal Reproductive Toxicology, after reviewing all the existing scientific literature on the subject, but noted many biases in the published literature.
This was avoided by Dr. Stefanie Hinkle and her colleagues at the universities of Utah (United States) and Haifa (Israel). They therefore carefully considered other factors known to increase the risk of miscarriage such as age, stress, lack of physical activity, overweight, alcohol, caffeine, tobacco, other disquieting causes.
Because nausea or vomiting during pregnancy is not always harmless. It may, for example, indicate a chromosomal abnormality (trisomy 21 and others) or multiple pregnancies. Situations that contribute to increasing the beta-HCG level, the hormone produced by the placenta (and that which is sought after pregnancy tests).

A peak at nine weeks gestation
“The theory is that beta-HCG can stimulate estrogen production by the ovaries, and estrogens are known to promote nausea and vomiting,” says Dr. Jennifer Niebyl of the University of Iowa in an article in the New England Journal of Medicine. “Nausea starts within four weeks of the last menstrual period in many patients,” adds Dr. Niebyl. The problem typically peaks at approximately nine weeks gestation, 60% of cases resolve at the end of the first trimester and 91% at the twentieth week. ”
The same trend of improvement in the second quarter was observed by Dr. Hinkle and colleagues in their study published in the Jamaica Internal Medicine. They examined the outcome of 797 women who started pregnancy among a group of 1,288 women between the ages of 18 and 40 who sought to do so. Women at increased risk of miscarriage because they had already done at least one in the past.
A quarter of these pregnancies (188 cases) were again terminated by a miscarriage, note the authors, generally in the first quarter (176 of 188), sometimes even before it is detectable by symptoms. Once in three (55 cases), the loss of the embryo occurred around the design period.
One of the interests of the study was to ask the women who participated in the study to record their symptoms every day in a booklet, in addition to daily urine tests and pregnancy tests. This allowed researchers to note that “nausea with or without vomiting was widespread, even in the first weeks of pregnancy. For example, about one in five women reported symptoms even before they had a positive pregnancy test. ”
It remains to be understood by what mechanism disorders as frequent as troublesome could “protect” the current pregnancy. The authors question whether nausea and vomiting are not simply the markers of a viable placenta: “Thus fewer nausea and vomiting could signal a compromised pregnancy, with less hormones to trigger them.”
How to identify symptoms of nausea?
As a general rule, nausea is the feeling of “vomiting” that precedes vomiting. It results in:
– strong salivation
– contraction of the muscles of the abdomen and pharynx.
In pregnant women, this nausea can be triggered by a simple odor or disgust for food. Also note: if one often speaks of morning sickness in the future mum, some women are confronted with the symptoms of nausea in the late afternoon or evening. In all cases, some simple hygiene measures help to alleviate this sensation and prevent vomiting.
Avoiding Nausea and Its Pregnancy Symptoms: 3 Golden Rules
- To reduce nausea and vomiting, drink and eat very fresh.
- Avoid strong odors and foods that bother you. Moreover, think of drinking plenty to rehydrate you, if vomiting is very common.
- Usually, nausea and vomiting, do not pose any risk to the mother and the fetus. However, if these discomforts become very severe, it is strongly advised to consult your doctor or midwife.
