Pre-pregnancy motion sickness in relation to NVP
15. PRE-PREGNANCY MOTION SICKNESS IN RELATION TO NVP
- Women who reported occurrences of travel sickness (n = 131) within 3/12 before pregnancy were more likely to vomit. 1,000 women in study population. Whitehead. (40)
- Women who generally suffered from travel sickness showed a difference in total hours of nausea which just failed to reach statistical significance at the 0.01 level. The women were asked if they had generally or ever suffered from travel sickness. Those who replied ‘generally’ had a median total hours of 58 hours of nausea compared to 33 hours for those who did not generally so suffer. (Mann-Whitney U Test P=0.032). This was not true for those who had ‘ever’ suffered travel sickness compared to those who had ‘never’ so suffered.
P = 0.32. 363 women in study population. Gadsby. (53)
- There was no difference in emesis rate in patients who suffered from motion sickness in the non-pregnant state compared to those who do not. 90 women in study population. (19)
- A history of nausea while travelling was unrelated to NVP or intensity of NVP.
160 women in study. (80)
- However, motion sickness was aggravated during pregnancy in emetic women. (19)
- What makes NVP worse?. Factors which interfere with the ability to use relief measures for NVP, travel (particularly to work). (109) 19 women in study kept diaries for seven days.
Women who suffered from pre-pregnancy travel sickness get more NVP.
