Nausea and vomiting are very common in the first weeks of pregnancy. Despite the name, "morning sickness" can strike at any time of day. It is usually harmless, but sometimes it needs treatment.

What to expect

According to the NHS, nausea and vomiting in pregnancy is very common in early pregnancy and usually eases between weeks 16 and 20. Everyone is different: some feel only mild queasiness, others are sick several times a day.

Self-help tips from the NHS

  • Get plenty of rest, as tiredness can make nausea worse.
  • Eat small, frequent meals of plain, carbohydrate-rich food such as dry toast or plain biscuits.
  • Have a dry biscuit or toast before you get out of bed.
  • If cooking smells bother you, choose cold food instead of hot meals.
  • Sip water regularly.
  • Ginger may help; ask a pharmacist before taking ginger supplements.
  • Acupressure on the wrist or forearm is worth a try.

Severe vomiting (hyperemesis)

For some women the sickness is so severe that it needs medical treatment, sometimes with fluids through a drip in hospital.
