Morning sickness in pregnancy

Nausea and vomiting in pregnancy, often known as morning sickness, is very common in early pregnancy.

It can affect you at any time of the day or night or you may feel sick all day long.

Morning sickness is unpleasant, and can significantly affect your day-to-day life. It usually clears up by weeks 16 to 20 of your pregnancy and does not put your baby at any increased risk.

There is a chance of developing a severe form of pregnancy sickness called hyperemesis gravidarum. This can be serious, and there's a chance you may not get enough fluids in your body (dehydration) or not get enough nutrients from your diet (malnutrition). You may need specialist treatment, sometimes in hospital.
