Pregnant Kate Middleton – who is expecting her third baby with Prince William – has revealed she is suffering with severe morning sickness once again.
The Duchess of Cambridge suffered with hyperemesis gravidarum in both 2012 during her first pregnancy with Prince George and in 2014 when she was expecting Princess Charlotte.
In fact, the severe morning sickness led to the hospitalisation of Kate Middleton and forced the royal family to announce her pregnancies early due to speculation.
Kensington Palace have now revealed the 36 year old has been struck down with the condition again, but what is it?

We spoke to Dr Renee HoenderKamp, who explained everything there is to know about hyperemesis gravidarum.
She told OK! Online exclusively: "Sickness in pregnancy is common. 1 in 7 women experience it. It usually subsides by approximately 14 weeks, although some women can experience it for the entire pregnancy.

"Otherwise known as morning sickness, this is often a misnomer, as some women can feel sick all day and even vomit all day. It is often triggered by eating or even smelling foods and some women find it very hard to tolerate even the blandest foods."
Explaining why hyperemesis gravidarum is different from your average bout of morning sickness, she revealed that only 1 in 100 women experience it.
Dr HoenderKamp added: "In severe cases the sickness can become dangerous when the woman is vomiting so much that she cannot tolerate any foods or liquid and is vomiting constantly. This is called hyperemesis gravidarum (HG) and can require hospital admission. It is not known how many women suffer this badly but estimates suggest 1 in 100."
The signs and symptoms of hyperemesis gravidarum include:

- Prolonged and severe nausea and vomiting – being sick up to 50 times a day
- Dehydration – not having enough fluids in your body; if you're drinking less than 500ml a day, you need to seek help
- Ketosis – a serious condition that results in the build-up of acidic chemicals in the blood and urine; ketones are produced when your body breaks down fat, rather than glucose, for energy
- Weight loss
- Low blood pressure on standing (hypotension)
Dr Renee HoenderKamp explained: "We don't know what causes HG but it often runs in families. We have treatments for HG which include several anti sickness medications and sometimes a woman has to go into hospital for fluid to be given via a drip (IV fluid).
"If severe and the woman is losing weight this is potentially dangerous for the baby."
She added: "It seems as if Kate Middleton's HG is severe and this will be why she is cancelling engagements: if she is vomiting constantly, feeling dizzy when standing from dehydration and generally feeling very unwell."
