Nausea and vomiting in pregnancy, also known as morning sickness, typically occurs in the first few months. Despite its name, the nausea can affect pregnant women at any time of day.
It is thought to be caused by the hormonal changes in the body of a pregnant woman in the first 12 weeks and usually clears up by 16 to 20 weeks. Although it can be quite unpleasant, it doesn’t pose an increased risk to the baby. If excess vomiting does occur it can lead to dehydration and malnourishment of the expectant mother in which case medical advice should be sought.
Rest, hydration with plenty of fluid and a healthy diet with little and often carbohydrate rich/low fat meals can be beneficial. Avoiding strong smells and focusing attention elsewhere can also help.
