Hyperemesis Ravidarum

Nausea and vomiting are very common in early pregnancy, affecting 50-80% of women. This is thought to be caused by high levels of pregnancy hormones from the placenta, and is more common in twin pregnancies.
Less common, is a severe and intractable form of nausea and vomiting in pregnancy, known as hyperemesis gravidarum. It is a diagnosis of exclusion and may result in weight loss; nutritional deficiencies; and abnormalities in fluids, electrolyte levels, and acid-base balance. The peak incidence is at 8-12 weeks of pregnancy, and symptoms usually resolve by week 20 in all but 10% of patients.
This more severe form usually necessitates a short stay in hospital to allow intravenous rehydration and treatment with anti sickness medication. Your baby will not be affected as long as appropriate treatment is administered.
