Sickness in pregnancy (sometimes called morning sickness) is common. Around 8 out of every 10 pregnant women feel sick (nausea), are sick (vomiting) or both during pregnancy. This does not just happen in the morning.
For most women, this improves or stops completely by around weeks 12 to 20, although for some women it can last longer.
Some pregnant women experience very bad nausea and vomiting. They might be sick many times a day and be unable to keep food or drink down, which can impact on their daily life.
This excessive nausea and vomiting is known as hyperemesis gravidarum (HG), and often needs hospital treatment.
Exactly how many pregnant women get HG is not known as some cases may go unreported, but it's thought to be around 1 to 3 in every 100.
If you are being sick frequently and cannot keep food down, tell your midwife or doctor, or contact the hospital as soon as possible.
There is a risk you may become dehydrated, and your midwife or doctor can make sure you get the right treatment.
