Signs, Symptoms, and Treatment

Hyperemesis gravidarum is a condition characterized by severe nausea, vomiting, weight loss, and electrolyte disturbance. Mild cases are treated with dietary changes, rest, and antacids. More severe cases often require a stay in the hospital so that the mother can receive fluid and nutrition through an intravenous line (IV). DO NOT take any medications to solve this problem without first consulting your health care provider.

What causes such severe nausea?

The majority of pregnant women experience some type of morning sickness (70 – 80%). Recent studies show that at least 60,000 cases of extreme morning sickness called hyperemesis gravidarum (HG) are reported by those who treated in a hospital but the numbers are expected to be much higher than this since many women are treated at home or by outpatient care with their health care provider.

It is believed that this severe nausea is caused by a rise in hormone levels; however, the absolute cause is still unknown. The symptoms of HG usually appear between 4-6 weeks of pregnancy and may peak between 9-13 weeks. Most women receive some relief between weeks 14-20, although up to 20% of women may require care for hyperemesis throughout the rest of their pregnancy. There is no known prevention of Hyperemesis gravidarum but you can take comfort in knowing that there are ways to manage it.
