Morning sickness should go away in the second trimester. In rare cases, less than 2 percent of pregnancies, this pregnancy-related nausea and vomiting can become so severe that you begin to lose weight and you are unable to keep down any food or fluids.
Fact: Almost all women who suffer from severe vomiting during pregnancy completely recover and gain adequate weight for a happy outcome.
This severe morning sickness is called hyperemesis gravidarum.
Hyperemesis gravidarum is the leading cause of hospitalization during early pregnancy.
Some pregnant women have a higher risk for developing this complication. These include women carrying multiples, women with a family history of hyperemesis gravidarum, those carrying a girl baby, those who have experienced this severe morning sickness in other pregnancies, and women with a history of motion sickness or migraines.
Because women who suffer from severe morning sickness experience excessive vomiting, they are often hospitalized with dehydration.
treat them, they are given fluids through an IV line and with a round of anti-nausea medications.
Fact: If you experience hyperemesis gravidarum during this pregnancy, you have a 15 to 20 percent chance of it recurring in your next pregnancy.
Most often, they do not receive any food until the vomiting stops.
The cause of severe morning sickness is not known, but several theories have been developed.
These include elevated pregnancy hormones, decreased gastric motility (the food sits in your stomach and doesn't digest correctly, causing indigestion and pressure), and emotional turmoil (you have a hesitancy about your pregnancy that you are not voicing, so your feelings are converted into severe vomiting).
If you have to be re-admitted to the hospital on multiple occasions for severe morning sickness and you do not gain the recommended amount of weight, there's a small chance that your baby will weigh less than normal.
