Severe vomiting in pregnancy: hyperemesis gravidarum

Around 7 out of every 10 pregnant women experience nausea or vomiting. Up to 1 in every 100 pregnant women experience excessive vomiting, known as hyperemesis gravidarum (HG). They often need hospital treatment as they are unable to eat.

You may also need special support
HG can affect you both emotionally and physically. The symptoms not only make your life miserable but may lead to further health complications, such as depression. The illness can be exhausting and stop you from doing everyday tasks. You might also feel:

How to get emotional support?
