Restless legs syndrome in pregnancy: Peak prevalence and postpartum trends

The prevalence of restless legs syndrome peaks in the third trimester of pregnancy and normalizes post-delivery.

Restless legs syndrome (RLS) is a movement disorder that worsens during pregnancy, leading to poor sleep, decreased daytime energy, and potential psychological issues in the postpartum phase. This study was carried out to assess the RLS prevalence during pregnancy and postpartum period.

The International Restless Legs Severity Rating Scale (IRLSS) assessed RLS symptoms in a total sample of 390 participants: 260 pregnant women and 130 female students (control group). Pregnant females were monitored at three points—during the third trimester, two months postpartum, and six months postpartum—while the control group had a single measurement.

RLS prevalence was found to be highest during the third trimester of pregnancy at 26.5%. It dropped to 18.1% two months postpartum and further decreased to 7.3% six months after delivery, nearing the control group's prevalence of 6.2%.

RLS prevalence peaks in the third trimester of pregnancy and declines after delivery, approaching the standard population rate by six months postpartum.
