The Duchess of Cambridge just have birth to a boy! We can't wait to see Kate and Will's new bundle of joy, but let's remember: like with her other pregnancies, this one wasn't easy.
It was announced in September of last year that the Duchess of Cambridge was suffering through hyperemesis gravidarum (HG) during her third pregnancy. The severe vomiting and constant nausea associated with HG often leads to dehydration and food aversion. The sight, smell or even thought of food can cause such a severe reaction that women with the condition can lose 5% or more of their pre-pregnancy weight.
While doctors haven't determined the exact , many scientists believe that a rise of hormone levels during the first trimester may trigger the extreme nausea. Most women with the disease see their worst symptoms subside after the thirteenth week of pregnancy, but about 20% will suffer until the baby arrives. In addition to bed rest and a bland diet, treatment options include homeopathic remedies like ginger or acupressure, but the most severe cases require hospitalization, IV fluids and feeding tubes.
The Duchess did spend three days in the hospital while pregnant with Prince George, but thankfully stayed well enough during her second pregnancy to avoid a repeat visit. Just like in Kate's case, having HG once often means you'll have it again. It's also known to run in families.
Unfortunately for Pippa, sisters of HG sufferers are 17 times more likely to develop the disease, according to . But again, for most women (emphasis on most), hyperemesis gravidarum ends within the first trimester.
