hyperemesis gravidarum

Continuous vomiting, weight loss and dehydration are referred to as hyperemesis gravidarum. Although hyperemesis gravidarum does not pose a risk to the pregnancy or the pregnant woman, it is still troublesome. As it occurs slightly more often with multiple pregnancy, it is discussed in this regard.

Nausea and vomiting are the first signs of pregnancy for many women. Approximately 80-85% of all pregnant women are affected to some degree by nausea, and well over half of them also experience vomiting.

By contrast, hyperemesis gravidarum occurs only rarely and only in the first half of pregnancy. The actual cause is unknown although it appears to correlate with the amount of pregnancy hormone that is produced, which would explain why it is more common with multiple pregnancy.

Blood and urine tests taken after dehydration occurs are useful to confirm the diagnosis. The dividing line between “normal” vomiting due to pregnancy and hyperemesis gravidarum is not always clear.

In women experiencing incessant vomiting in combination with weight loss and dehydration, then admission into hospital may be necessary. In general, the symptoms disappear quickly after admission. In some cases, fluid is administered through a drip in order to combat the dehydration. Vitamin deficiency does not occur easily, but if the vomiting continues for a lengthy period of time, it can sometimes be necessary to administer vitamins (especially vitamin B1). While this condition is very troublesome, it is a reassurance that the prognosis – outlook - is generally good.
