Hyperemesis Gravidarum (HG)


Nausea and vomiting are some of the most well-known and common symptoms of early pregnancy, but fewer women know that it can become severe, persistent, and debilitating. More than typical morning sickness, hyperemesis gravidarum (HG) is a medical condition that requires specialized medical care from an OB/GYN provider. At Materna, we offer HG care in early pregnancy, helping you feel more comfortable, confident, and healthy through every week of it.
What is Hyperemesis Gravidarum (HG)?
Hyperemesis gravidarum (HG) is a condition where you experience intense, persistent nausea and vomiting during pregnancy. Because of the persistent nausea and vomiting, it can be difficult to eat or drink, leading to health issues like weight loss, dehydration, iron deficiency, electrolyte imbalance, and more. It can become so severe that it interferes with daily life and the health of your baby.
For many women, HG can be extremely distressing, leading to long-lasting health problems and even disrupting their plans for pregnancy. If you’re worried about HG or have had past experiences with it, we can help.
It includes:
- Nausea throughout the day
- Occasional vomiting
- Difficulty tolerating some foods and liquids
- Mild weight loss ( about 5% or less of your pre-pregnancy weight )
These symptoms tend to be more manageable than moderate or severe HG, but it’s important to pay attention to your symptoms, track them, and seek out care from our OB/GYN providers if they worsen.
Includes:
- Dehydration and difficulty keeping fluids down
- Fatigue and weakness
- Noticeable weight loss
- Frequent vomiting
This is the point where we recommend getting medical help, if not sooner. Nutritional support, infusions, and IV hydration are key at this stage to keep you and your baby in good health.
It includes:
- Rapid weight loss
- Severe dehydration (dry mouth, dizziness, dark urine)
- Electrolyte imbalance
- Nutritional deficiencies
- Inability to keep food or fluids down for 24+ hours
Many women go to urgent care or the emergency room for severe HG. We can offer prompt treatment and help you preserve your health and your baby’s.
