Hyperemesis is a severe type of nausea and vomiting during pregnancy. Although many pregnant women have morning sickness, for some, it’s much more intense. There is no cure for hyperemesis, but it's temporary, and there are ways to manage it.

Overview and Symptoms
Unlike morning sickness that’s associated with the first trimester of pregnancy, hyperemesis usually lasts longer. The cause is unknown, but it’s believed to be a result of a rise in hormone levels. With hyperemesis, persistent vomiting, dizziness and weakness may keep you from your normal activities. This can also lead to problems such as dehydration and weight loss. Symptoms usually get better by the 20th week, but not always. 

Treatment at BIDMC

Hyperemesis can affect the level of electrolytes in your body, including sodium and potassium. Your doctor may recommend electrolyte-replacement drinks and nutritional supplements such as thiamine (vitamin B1) or ginger to help ease vomiting.
 
Your doctor may also prescribe one or more medications, and will work with you to ensure anything you take is safe for you and your baby. These anti-nausea medications may come in the form of a pill, shot or intravenous.
