About HG

The research on hyperemesis gravidarum (or HG) is limited compared to some diseases; however, there is some information we do know.

Causes of HG

There are no known causes of hyperemesis gravidarum, only theories, but it is likely that HG is caused by a number of interrelated factors that vary by woman and by pregnancy. Treatment thus differs because women will respond differently to medications and other interventions. What is known, however, is that it is not all in your head. Sadly, some health professionals are not aware of the research proving physiological changes are responsible. It is truly a disorder of pregnancy that requires serious attention to avoid a worsening of symptoms and complications.

Possible Complications

When HG is treated early and effectively, you may still be somewhat miserable, but you and your baby will likely not suffer any serious complications. You will likely experience fatigue, depression, anxiety, and stomach or throat pain. Other complications become possible if your symptoms are severe or prolonged. Adequate care and social support decrease the risk of more debilitating complications.

Risks & Outcomes

Most mothers with HG have normal babies and recover within months of delivery. However, those who are given inadequate care, becoming malnourished and chronically dehydrated, are at greater risk for problems with mom and/or baby.

Research shows that women who lose more than 10% of their body weight and/or who are unable to gain weight for two or more consecutive trimesters are most likely to have complications. Although medications present a risk, dehydration and starvation also can harm the baby. Early intervention is the best strategy to avoid complications for both mother and baby.
