Answer

Pregnancy is another causative factor in RLS, which is estimated to affect 25-40% of pregnant women. The syndrome usually subsides within a few weeks after delivery. However, in one long-term, follow-up study, women who developed RLS during pregnancy had a 4-fold increased risk of developing chronic RLS compared with women who did not have RLS when pregnant.
