Hyperemesis Gravidarum Transferred From Mother To Daughter

Hyperemesis Gravidarum Transferred From Mother To Daughter.
The daughters of women who suffered from a undecorated genus of morning sickness are three times more likely to be plagued by it themselves, Norwegian researchers report. This kind of morning sickness, called hyperemesis gravidarum, involves nausea and vomiting beginning before the 22nd week of gestation. In grievous cases, it can leadership to weight loss.

The condition occurs in up to 2 percent of pregnancies and is a common cause of hospitalization for parturient women. It is also linked with low birth weight and premature birth, the researchers said. The different study suggests "a strong influence of maternal genes" on the increment of the condition, said lead researcher Ase Vikanes, a graduate student at the Norwegian Institute of Public Health in Oslo.

So "However, environmental influences along the nurturing line, shared jeopardy factors such as life styles reflected in BMI (body mass index) and smoking habits, infections and nutrition might also be contributing to the evolution of hyperemesis gravidarum". The report is published in the April 30 online version of the BMJ.

According to Vikanes, hyperemesis gravidarum was once thought to be caused by psychogenic issues, "such as an unconscious rejection of the child or partner". But her team wanted to conscious of if genetics was actually the culprit. For the study, Vikanes's team collected information on 2,3 million births from 1967 to 2006. They tracked the incidence of hyperemesis gravidarum in more than 500,000 mother-daughter pairs and almost 400,000 mother-son pairs.
