Anyone who has experienced nausea and vomiting in pregnancy can attest to the misleading nature of the title ‘morning sickness’.

For many, morning sickness can last all day, often for most of the first trimester, and sometimes beyond.

For some, it doesn’t end until the baby and placenta are born.

Hyperemesis Gravidarum affects one to two per cent of pregnant people, causing debilitating nausea and vomiting for most if not all of pregnancy.

It is diagnosed when nausea and vomiting of pregnancy are extremely severe (up to 50 times a day in some cases), persists past the first trimester, or results in a weight loss of at least five percent of pre-pregnancy weight.

The condition is serious and can lead to dehydration and malnutrition of both mother and baby, as well as increased risk of weight loss and preeclampsia. Half of all mothers with Hyperemesis Gravidarum may also develop depression or anxiety.
