Pregnancy hormones affects RLS

A new study has found that hormonal changes related to pregnancy can increase the risks of restless legs syndrome (RLS).

RLS can disturb a person's ability to sleep or return to sleep after awakening, with the study finding that estrogens can play in important role in the disorder during pregnancy.

According to the report's authors, RLS can occur for the first time during pregnancy, with symptoms getting worse during the child-carrying period.

Thomas Pollmacher, professor of psychiatry at Ludwig Maximilians University in Munich, Germany, said: "Our findings strongly support the concept that neuroactive hormones play a relevant pathophysiological role in RLS".

He added: "This information will increase the understanding of RLS in pregnancy and will assist in the development of specific therapeutic approaches."

Scientists from the Yale School of Medicine recently found that women who suffer from preeclampsia during their first pregnancy will have increased "subsequent hypertension risks" with each further pregnancy.
