High blood pressure in pregnancy increases heart risk in babies, says study

A new study says that higher blood pressure during early pregnancy increases the baby's risk of congenital heart defect.

A congenital heart defect is a problem with the structure of the heart. It can involve the walls of the heart, the valves of the heart, and the arteries and veins near the heart. It is present at birth.

The research was done in the US on 19,107 pairs of mothers and their babies born between 2009 and 2015.

It was found that women having an increase of 10 milligrammes per decilitre in blood glucose levels had eight percent higher risk of giving birth to a child with a congenital heart defect.
