Restless Legs Syndrome and Menopause

The urge to move your legs at night is more common in midlife — here is why and what helps.

Key takeaways

RLS prevalence increases during perimenopause, affecting up to 25% of women in the transition
Estrogen and dopamine are linked — hormonal fluctuations may unmask or worsen RLS
Iron deficiency is a common and treatable cause — serum ferritin should be checked
RLS severely fragments sleep and is distinct from periodic limb movement disorder (PLMD)
First-line treatments include iron supplementation, moderate exercise, and avoiding triggers

Restless Legs Syndrome (RLS) is a neurological disorder that becomes more common during the menopause transition.

How common? RLS affects about 5-10% of the general population, but prevalence rises to 20-25% in perimenopausal women. The SWAN Study confirmed that the transition period is a high-risk window.

Why menopause? Estrogen influences dopamine signaling, and dopamine dysfunction is central to RLS. Hormonal fluctuations during perimenopause may unmask a latent tendency or worsen existing RLS.

Diagnostic criteria (IRLSSG): 1) Urge to move legs, 2) Worse at rest, 3) Relieved by movement, 4) Worse in evening/night, 5) Not explained by another condition.

First-line treatment:

Check ferritin — if serum ferritin is below 75 mcg/L, iron supplementation is first-line. Many women are iron deficient from heavy periods.
Avoid triggers — caffeine, alcohol, antihistamines, and some antidepressants worsen RLS
Moderate exercise — regular walking significantly reduces symptoms
Magnesium — some evidence for mild symptom reduction

⚠️ If iron supplementation and lifestyle changes do not help, see a sleep specialist. Prescription medications exist but have side effects.
