Is Kate Middleton’s morning sickness a sign she’s pregnant with twins?

Hyperemesis Gravidarum is more commonly associated with multiple births

The severe morning sickness – known as Hyperemesis Gravidarum – that the Duchess of Cambridge is experiencing in the early stages of her first pregnancy could be a sign she’s expecting twins, say experts.

Hyperemesis is a very rare condition. Estimates vary but in the UK it’s thought to affect just one or two per cent of pregnancies.

First time mums-to-be are more likely suffer from the condition and those who are pregnant with multiples are at a 7.5 per cent higher risk than those expecting a single baby, according to Dr. Ashley Roman, professor and OB/GYN at New York University Langone Medical Center, speaking to ABC.Are Kate and Wills expecting the first pair of royal twins? ©Rex

More intense morning sickness is also linked to female babies, though it’s far too early for the Duke and Duchess to have found out the sex. Whether the baby is a girl or a boy, it will become the third in line to the throne (after its granddad the Prince of Wales and dad Prince William).


And just as a hair cut sparked rumours of a pregnancy, Kate’s hair could give away whether she’s expecting a boy or girl (if not twins). The old wives’ tale goes that mums-to-be expecting a boy enjoy extra shiny, thick hair, while those expecting a girl suffer dull hair and even thinning.

Other signs of twins include exaggerated pregnancy symptoms, such as a bigger bump and extreme fatigue. But it’s unusual for twins to be born with no family history of them, and this would be a first for the Royal Family.


The eyes of the world have been on Kate ever since her and William’s engagement announcement and speculation is bound to get more intense. We hope she’s feeling better soon.
