GOOD news for the Duchess of Cambridge and other queasy mothers-to-be — morning sickness really does indicate a healthy pregnancy.
Kate, who is expecting her third child, has had to cancel engagements during her pregnancies due to severe morning sickness, although she was delighted to meet well-wishers at the Children’s Global Media Summit in Manchester yesterday.
Now researchers have established that there’s a truth behind the old wives’ tale.Their paper, published in the Journal of Molecular Endocrinology, discusses the importance of the peptide hormone endokinin for healthy pregnancies and how it acts on the brain to induce nausea and vomiting. But its normal function may be impaired by smoking, leading to poor outcomes in pregnancy, they add.
Prof Philip Lowry and Dr Russell Woods, of Reading University, reviewed the roles of endokinin in ensuring successful implantation of the placenta and how the hormone can indirectly lead to the development of morning sickness symptoms. That is why drugs that block the actions of endokinin in the brain are often used to treat nausea associated with chemotherapy, they said.
Given that smoking during pregnancy is known to lead to poor placental implantation, Prof Lowry said that suggests that impaired endokinin activity may be involved.
He added: ‘I hope that this will give some psychological relief to pregnant women suffering from morning sickness, but will also persuade smokers who are intending to have a baby to kick the habit well beforehand.’
■ PRINCE George played a sheep in his school nativity play, his father told children yesterday.
The Duke of Cambridge revealed: ‘I went to my boy’s nativity play. It was funny. He was a sheep.’
George, four, is in his first term at school at Thomas’s in Battersea, south-west London.
