The cause is not known. It may be due to a problem in a certain enzyme in the mother.
Things that may raise the mother's risk are:
- Being pregnant with more than one child
- First pregnancy
- A problem with the long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) enzyme
Some people do not have symptoms. Those who do have problems that are not specific. Most symptoms start in the third trimester.
Problems may be:
- Nausea and vomiting
- Lack of hunger
- Yellowing of the skin and whites of the eyes
- Weight loss
- Belly pain
- Excess thirst
- Passing more urine than usual
The doctor will ask about symptoms and health history. A physical exam will be done.
Tests that may be done are:
- Blood tests to check liver function
- Urine tests to look for signs of kidney damage
Images may be taken to check liver size. This can be done with an ultrasound.
The only way to cure this condition is to deliver the baby. The decision to do so depends on how many weeks the person has been pregnant. Labor may happen on its own or it may be started by the doctor. Liver function will return to normal after delivery.
There are no guidelines to prevent this problem.
