Nausea and vomiting in pregnancy affect a significant number of pregnant women, ranging in severity from mild nausea to a more serious condition.
While nausea and vomiting in pregnancy are very common, that doesn’t make it any less exhausting to live with. For women experiencing severe symptoms, it can significantly affect daily life, work, and wellbeing. Dr Rozen provides support and management options for patients across the full spectrum of severity, from practical strategies for mild symptoms to medical treatment for those whose nausea is more debilitating.
Morning sickness, a common symptom of pregnancy, often occurs in the first trimester and is characterised by nausea and vomiting. Despite its name, morning sickness can strike at any time of day or night. It affects a significant number of pregnant individuals, with varying degrees of severity from mild nausea to the more severe condition known as hyperemesis gravidarum.
For most women, symptoms begin around week six and tend to improve by the end of the first trimester, though some experience them for longer.
The exact cause is not fully understood, but it is believed to be related to the rapid hormonal changes of early pregnancy, particularly the rise in human chorionic gonadotropin (hCG) and oestrogen.

Nausea and vomiting during pregnancy requires treatment options ranging from dietary and lifestyle adjustments for mild symptoms to medical intervention for more severe cases.
Eating small, frequent meals throughout the day rather than three large meals can help settle the stomach. Bland, dry foods such as crackers are often well tolerated. Spicy, fatty, or strongly odorous foods are best avoided.
Staying hydrated is important, particularly if vomiting is frequent. Small, frequent sips of water or ginger ale are easier to manage than large amounts at once.
Ginger supplements or ginger tea are commonly recommended for their nausea-reducing properties and are generally considered safe in pregnancy.
Vitamin B6 supplementation has been shown to help reduce the severity of nausea in pregnancy and is often recommended as a first-line option.
Fatigue can worsen nausea, so adequate rest is an important part of managing symptoms.
For women with severe morning sickness or hyperemesis gravidarum, medical treatment may be necessary. This can include anti-nausea medications, IV fluids for hydration, and in some cases, hospitalisation to manage dehydration and nutritional deficiencies.
Treatment for severe morning sickness isn’t always straightforward. While nausea and vomiting in pregnancy are generally not harmful to the pregnancy itself, it is important to seek medical attention if you experience any of the following:
For most women, starting with a GP is the right first step. For more information, the Royal Women’s Hospital provides a helpful resource on common concerns in early pregnancy.
