Signs & symptoms

Women with hyperemesis gravidarum vomit every day, often many times a day. They can lose weight and get dehydrated because of the vomiting.
Symptoms of dehydration include:
- Urinating less often than usual
- Having dark yellow urine
- Feeling dizzy when standing up
- Weight loss
Symptoms of hyperemesis gravidarum usually start during the first 2 to 3 months of pregnancy. Most women feel better by the middle of their pregnancy. But some feel sick until late in the pregnancy.


Diagnosis will be made by your doctor based on your symptoms and physical exam.


Treatment depends on how severe the symptoms are. If you are dehydrated or have lost a lot of weight, you will probably need to be treated in the hospital with:
- Fluids that go into the vein through a tube called an "IV"
- Medicines to help stop the nausea and vomiting
If this treatment doesn't work, the doctor can offer feeding through a tube that goes in the nose and down into the stomach or through a vein.
