Severe Morning Sickness Could Worsen Mental Health Issues & Cause Serious Complications, Study Finds


This week, British researchers published new findings on the impact of hyperemesis gravidarum (HG) — an extreme form of morning sickness — on women’s mental health. The condition can cause extreme and uncontrollable bouts of nausea and vomiting, according to the study. But more than that, women with HG often suffer from dehydration, malnutrition, weight loss, and fatigue so severe that they become incapable of caring for themselves. So it’s probably not surprising that the study found severe morning sickness can worsen mental health issues for pregnant women — increasing their chances for seeking abortion, self-harm, or even suicide, the researchers concluded.

University of Plymouth researchers conducted the study with support from UK charity Pregnancy Sickness Support (PSS). The team interviewed 446 women about their HG symptoms and found that, along with the debilitating physical symptoms of HG, the participants expressed similar feelings of social isolation, inability to care for themselves or others, extreme guilt, and a sense of dying or suicidal thoughts.

One patient told researchers about her difficult early pregnancy:

That level of misery might be tough to grasp if someone hasn’t experienced it themselves. Morning sickness, with its sudden and uncontrollable bouts of nausea and vomiting, is a fairly common pregnancy ailment. Some 70 to 80 percent of pregnant women deal with it at some point. Still, it’s the kind of thing you have to experience to fully understand.

For example, before I had kids, I thought of morning sickness as just a more sudden form of other kinds of nausea I’d been through: the flu, a hangover, or maybe even a roller coaster ride. Within a week of finding out I was pregnant, I realized how wrong I’d been. I had no idea that it was possible to be too nauseated to open my eyes, speak, or do anything other than cry. And anything — smells from the kitchen, our dog’s breath, my husband’s soap — could set me off. Some days in that awful first trimester, I lived off of ginger candy and dry cereal. And that was “just” morning sickness. For the thousands of women diagnosed with HG each year, it gets much, much worse.

In the study, another patient (who ultimately ended her pregnancy) explained the horrific experience that led to her decision:

She continued:

According to the report, published this week in the British Journal of Midwifery, researchers estimated that severe sickness is a factor in at least 1,000 pregnancy terminations per year in the U.K.

And the effects of HG don’t necessarily go away after a pregnancy ends, according to the HER (Hyperemesis Education and Research) Foundation. The nutritional and metabolic deficiencies associated with HG can pose long-term complications for both the woman and her baby, according to information on the HER website. As much as 68 percent of patients will lose income because they’re simply too ill to function (and, you know, we don’t offer universal paid leave to cover pregnancy or postpartum complications), so it stands to reason that women who suffer HG may also have post-traumatic stress disorder postpartum, according to HER.

Because HG is so complex, doctors have been unable to settle on a clear cause, according to HER. Still, the study authors said that the findings showed a need for more mental health support for HG patients while researchers try to understand the physical causes of the disease. Caitlin Dean, lead researcher for the review and PSS chairperson said:

Morning sickness is rough, but HG is far more serious and must be treated that way. If you’re pregnant and suspect you have HG — perhaps you’ve lost more than 5-10 percent of your pre-pregnancy weight, or you’re vomiting several times a day — don’t hesitate to tell your doctor. And if those physical symptoms are driving more emotional challenges like depression, isolation, or thoughts of self-harm, please know that there are resources available (online and in your community) so that you don’t have to deal with it alone.
