Restless Leg Syndrome during Pregnancy

Sleep disturbances are common during pregnancy. Pain, discomfort and frequent urination lead to sleep disturbances. While polysomnographic studies in pregnant women are limited, it has been reported that increased snoring, restless leg syndrome (RLS), non-restorative sleep, insomnia, periodic leg movements and sleep respiratory disorders are common in pregnant women and result in poor sleep quality. RLS is a sensorimotor disorder characterized by the urge to move the legs and with unpleasant sensations, which generally peaks during night and rest periods. Its prevalence during pregnancy is estimated to be higher than the general population. Pregnancy-related RLS is a disorder with unclear etiology, many possible contributing factors and a good prognosis. Non-pharmacological therapies should be considered first for treatment, and risks and benefits of therapy should be evaluated individually if pharmacological treatment will be given.
