Sick­ness is a sign of health

The Daily Telegraph (Sydney) - - News -

IT has long been dis­missed as an old wives’ tale — morn­ing sick­ness signals a healthy preg­nancy.

But ex­perts now say it is prob­a­bly true, giv­ing en­cour­age­ment to suf­fer­ers, who fa­mously in­clude the Duchess of Cam­bridge. More than four in five women bat­tle nau­sea in the first 12 weeks of preg­nancy, and around half ex­pe­ri­ence vom­it­ing.

Sci­en­tists at the Univer­sity of Read­ing say the sick­ness may be a good thing as it is caused by a hor­mone vi­tal for a healthy preg­nancy. En­dokinin, which acts on the brain to cause morn­ing sick­ness, also en­sures good blood flow through the pla­centa so that oxy­gen and nu­tri­ents can reach the un­born baby.

Pro­fes­sor Philip Lowry, from the Univer­sity of Read­ing’s school of bi­o­log­i­cal sciences, said he hoped the news would bring ‘‘psy­cho­log­i­cal re­lief’’ to preg­nant women.

“There may be a temp­ta­tion to use en­dokinin-block­ing drugs to treat morn­ing sick­ness dur­ing preg­nancy, but these find­ings sug­gest that such drugs could af­fect the health of the preg­nancy and must be avoided,’’ he said.

Morn­ing sick­ness does not en­dan­ger ba­bies and usu­ally clears up by weeks 16 to 20.
