But sometimes the symptoms are so extreme — severe, persistent nausea, vomiting, and weight loss during pregnancy — that it may be diagnosed as a less common disorder known as hyperemesis gravidarum.
Signs and Symptoms of Hyperemesis Gravidarum
- Feeling dizzy, lightheaded, and faint
- Losing more than 5 percent of body weight
- Becoming dehydrated, with signs of dehydration such as dark urine and dry skin
- Electrolyte and nutritional imbalances
- Increased salivation
- Rapid heart rate
- Low blood pressure
- Headaches
- Yellowing of the skin and eyes (jaundice)
- Depression and anxiety
How Is Hyperemesis Gravidarum Diagnosed?
Your doctor will perform a physical exam and order the following lab tests to assess signs of dehydration.
- A complete blood count
- A serum electrolyte test (blood test)
- Ketones urine test (when the body isn't getting enough nutrients, it begins to break down fat, which leads to an increase in waste products known as ketones)
