There is no necessary link between moving into a newly renovated house and hyperemesis gravidarum. The development of hyperemesis gravidarum is associated with nutritional deficiencies, viral infections and maternal endocrine disorders. There are no studies showing that the development of hyperemesis gravidarum is associated with newly renovated houses. However, newly renovated houses may have excessive levels of some chemicals, such as excessive formaldehyde and benzene, which may cause other diseases in the organism. The occurrence of hyperemesis gravidarum is mainly related to factors such as maternal nutritional deficiency, viral infection and endocrine disorders. If the mother has nutritional deficiencies, the organism lacks folic acid or vitamin A, or if there is a viral infection, or if there are abnormalities in the ovarian function that lead to low levels of estrogen, there is a possibility that this may lead to the development of gravidas. Although there is no necessary link between moving into a newly renovated house and gravidas. However, since newly renovated houses contain non-volatile formaldehyde, benzene and other substances, it is recommended that women who are preparing for pregnancy should not live in newly renovated houses, or else it may have an effect on the fetus and cause fetal malformation.
