• #25 The onset of nausea and vomiting of pregnancy: a prospective cohort study | BMC Pregnancy and Childbirth | Full Text

  https://bmcpregnancychildbirth.biomedcentral.com/articles/10.1186/s12884-020-03478-7

  Nausea and vomiting are experienced by most women during pregnancy. The onset is usually related to Last Menstrual Period (LMP) the date of which is often unreliable. This study describes the time to onset of nausea and vomiting symptoms from date of ovulation and compares this to date of last menstrual period. Almost all women (88%) had Human Chorionic Gonadotrophin rise within 8 to 10 days of ovulation; the equivalent interval from LMP was 20 to 30 days. Many (67%) women experience symptoms within 11 to 20 days of ovulation. Onset of nausea and vomiting occurs earlier than previously reported and there is a narrow window for onset of symptoms. From ovulation, symptoms start approximately two weeks earlier, and are more concentrated than from LMP. Two-thirds of women have onset within 11 to 20 days from ovulation day, and only 5% have earlier onset. The median from ovulation to symptom onset is 16 days and from LMP is 32 days. Symptoms start slightly earlier for women with higher BMI values, by about one day for an increase of 5 kg/m2. Symptoms start slightly later with increasing age, by almost one day for an increase of 3 years. Symptoms disappeared by week 7 from LMP for 20 (8%) of the volunteers, 11 of whom never vomited and 16 of whom had symptoms less than 2 hours per day. This paper describes for the first time the onset of symptoms of nausea and vomiting in pregnancy from the day of ovulation. The vast majority of women (94%) experienced symptoms which started within a clear, narrow time window from ovulation. In particular, symptoms began between days 11 and 20 for 67% (n = 160) of the 241 participants with NVP. The close connection between onset of NVP symptoms and date of ovulation reinforces the theory that the aetiology of the condition is biological, rather than psychiatric, and is based on the emerging physiology at the foetal-maternal interface. Onset of symptoms of nausea or vomiting was earlier than reported in other articles: median from LMP at day 32, compared to day 57, 8 weeks or 5 weeks. The mean day of onset of NVP symptoms in this study is day 18 from ovulation, while from LMP it is day 34. Onset of NVP occurs earlier than previously reported and there is a narrow window for onset of symptoms from ovulation.

  Aversion to and avoidance of certain foods also peaks during the first trimester for many pregnant women. The most-observed aversion was to meats, fish, poultry and eggs the foods that were more likely to carry harmful microorganisms and parasites before the advent of modern refrigeration and food-handling processes. […] The Cornell biologists emphasize that their findings on the usefulness of morning sickness should not alarm women without NVP. […] Our analysis of thousands of pregnancies shows that most women in Western societies bear healthy babies whether or not they experience morning sickness. The lack of NVP symptoms does not portend pregnancy failure any more than experiencing NVP guarantees that the pregnancy will have a positive outcome. […] Attempting to alleviate the symptoms of „normal” (not severe) NVP probably will not improve the outcome of a pregnancy and could have the opposite effect if treatment interferes with the expulsion or avoidance of potentially dangerous foods. […] Encouraging women to eat foods they dislike during pregnancy will not improve the pregnancy outcome and could increase the embryo’s exposure to pathogens and harmful chemicals.

  Lack of NVP symptoms was associated with increased risk for SAB [adjusted odds ratio (OR) = 3.2, 95% confidence interval (CI): (2.4, 4.3)], compared with having any symptoms. […] The absence of NVP symptoms is associated with an increased risk of early pregnancy loss. As symptom duration decreases, the likelihood of early loss increases, especially among women in the oldest maternal age group. […] The overall mean symptom duration was eight gestational weeks. […] When vomiting was at its worst, 51% reported vomiting once a day and 13% reported having more than three vomiting episodes daily. […] Week-specific conditional probability of SAB by NVP status and symptom duration is shown in Fig. 1. There was a 3- to 10-fold increase in risk of first trimester pregnancy loss for women without NVP symptoms, compared with women who experienced some NVP symptoms; however, the risk of SAB for women without NVP symptoms reverts to the baseline risk after the first trimester.

[…] Our findings also provided insights into the contribution of maternal age in the etiology of SAB. The effects of symptom severity and duration were found to be different across maternal age groups. […] In conclusion, we found, as have others, the presence of NVP decreases the risk of SAB, with this decrease higher in women 30 years and older. We also found that the effect of symptom duration is greatest among that group.
