Nausea is one of the most common symptoms of pregnancy, affecting about 70% of all pregnancies. Normally, these challenging symptoms sharply decline after weeks 10-16. Many cases of nausea fall under the umbrella term \u201cmorning sickness,\u201d though around 2% of people will experience severe and long-lasting symptoms called Hyperemesis Gravidarum (HG).<\/span><\/p>\n\n\n\n

What causes it?<\/strong><\/h4>\n\n\n\n

Nobody knows for sure what causes typical morning sickness, but the most popularly attributed cause of nausea during pregnancy is the large and sudden changes in<\/span> hormones. Thankfully, researchers in 2023 discovered the cause of HG, which is one of the leading causes of hospitalization in pregnancy. A genetic variant causes some people to have low levels of a hormone called GDF15 before pregnancy and very high levels after becoming pregnant. Research has already started to examine targeted prevention strategies.<\/span><\/p>\n\n\n\n

If you\u2019re unable to eat or drink for more than 24 hours, are vomiting multiple times per day, losing weight, are feeling dehydrated or dizzy, or just aren\u2019t sure if your level of morning sickness is normal – be sure to reach out to your OB provider or seek more urgent help. HG often requires treatment. It may be medication you take at home or IV therapy when it\u2019s at its worst. People suffering from HG may also need mental health support to cope with the unexpected physical demands of this pregnancy condition.<\/span><\/p>\n\n\n\n
