Morn­ing sick­ness may be good news

The Sun (Malaysia) - - FAMILY TIES -

MORN­ING sick­ness is linked to a lower risk of mis­car­riage, ac­cord­ing to new re­search that sug­gests a woman’s nau­sea and vom­it­ing early in preg­nancy may have pro­tec­tive ef­fects for the foe­tus.

Be­tween 50% and 80% of preg­nant women re­port feel­ing nau­seous or ex­pe­ri­enced vom­it­ing dur­ing their first trimester, said the find­ings in the Jour­nal of the Amer­i­can Med­i­cal As­so­ci­a­tion (JAMA) In­ter­nal Medicine.

The con­di­tion is of­ten called “morn­ing sick­ness,” though it can af­fect women at all times of the day and night.

In a study of 797 women, both feel­ings of nau­sea, and nau­sea with vom­it­ing, were associated with a 50% to 75% re­duc­tion in the risk of preg­nancy loss, said the re­port, which was led by En­rique Schis­ter­man of the US Na­tional In­sti­tute of Child Health and Hu­man De­vel­op­ment.

The women in the study had all had one or two prior preg­nancy losses. They tracked their nau­sea symp­toms in a diary, and their preg­nan­cies were con­firmed by urine tests.

Prior re­search has also sug­gested that nau­sea and vom­it­ing are linked to a lower risk for preg­nancy loss.

Some ex­perts be­lieve this is be­cause feel­ings of nau­sea may en­cour­age a healthy preg­nancy by lead­ing women to eat less, thereby re­duc­ing the risk of ex­pos­ing the foe­tus to tox­ins.

The re­duc­tion in food in­take also ap­pears to lower lev­els of cir­cu­lat­ing in­sulin and en­cour­age growth of the pla­centa, re­search has shown.

The new study, how­ever, did not delve into rea­sons why nau­sea and vom­it­ing may lower the risk of mis­car­riage. Re­searchers ad­vised that fur­ther stud­ies need to be done in or­der to fully ex­plore this link. – AFP-Re­laxnews
