HG typically includes nausea that doesn’t go away and severe vomiting that leads to severe dehydration. This doesn’t allow you to keep any food or fluids down.
The symptoms of HG begin within the first six weeks of pregnancy. Nausea often doesn’t go away. HG can be extremely debilitating and cause fatigue that lasts for weeks or months.

Almost all women experience some degree of morning sickness during their pregnancy. Morning sickness is nausea and vomiting during pregnancy. Despite the name, morning sickness isn’t confined to the morning. It can occur at any time.
Morning sickness and HG seem to have a connection to human chorionic gonadotropin (hCG). This is a hormone created during pregnancy by the placenta. Your body produces a large amount of this hormone at a rapid rate early in pregnancy. These levels can throughout your pregnancy.
Some factors that could increase your risk of getting HG are:
- having a history of HG in your family
- being pregnant with more than one baby

- being a first-time mother
Trophoblastic disease can also cause HG. Trophoblastic disease occurs when there’s an abnormal growth of cells inside the uterus.
Your doctor will ask you about your medical history and your symptoms. A standard physical exam is enough to diagnose most cases. Your doctor will look for common signs of HG, such as abnormally low blood pressure or a fast pulse.
Blood and urine samples may also be necessary to check for signs of dehydration. Your doctor might also order additional tests to rule out gastrointestinal problems as a cause of your nausea or vomiting.
An ultrasound might be necessary to find out if you’re pregnant with twins or if there’s are any problems. This test uses sound waves to create an image of the inside of your body.
Treatment for HG depends on the severity of your symptoms. Your doctor may recommend natural nausea prevention methods, such as vitamin B-6 or ginger.
Try eating smaller, more frequent meals and dry foods, such as crackers. Drink plenty of fluids to stay hydrated.
Severe cases of HG may require hospitalization. Pregnant women who are unable to keep fluids or food down due to constant nausea or vomiting will need to get them intravenously, or through an IV.
Medication is necessary when vomiting is a threat to the woman or child. The most commonly used anti-nausea drugs are promethazine and meclizine. You can receive either through an IV or as a suppository.
Taking medication while pregnant can cause potential health problems for the baby, but in severe cases of HG, maternal dehydration is a more concerning problem. Talk to your doctor about the risks associated with any method of treatment.
The good news is that symptoms of HG will disappear after giving birth. However, postpartum recovery may be longer for women with HG.
Talk with your doctor and pursue education and support groups to help you and your family deal with HG. Be sure to communicate your feelings to your doctor and personal support system.
