There are many theories about the causes of HG, but none have been confirmed. HG is a complex disease that is likely caused by many factors. Some of these include:

Vitamin B deficiency
Human chorionic gonadotropin (hyperemesis most severe during period of highest HCG levels)
Hyperthyroidism (may be a result of high chorionic gonadotropin levels)
Endocrine imbalances (high levels of estrogen)
A multiple pregnancy (ie, twins or more)
Brain nausea-control-center sensitivity to pregnancy changes

The Brain May Be Cause of Nausea
