An urge to move your legs that builds the moment you sit still in the evening, relieved only by getting up and walking — restless legs syndrome is common, it destroys sleep as effectively as night sweats, and it is almost never mentioned in menopause discussions. It is also one of the few sleep problems with a specific, checkable cause that is very common in perimenopausal women.
Where we stand: Menova is an independent publication. We sell no supplements and no medication, we are not your doctor, and this is general education, not a diagnosis.
What it actually is
Restless legs syndrome — also called Willis-Ekbom disease — has four defining features, and all four need to be present:
- An urge to move the legs, usually with an uncomfortable sensation described as crawling, pulling, aching, or fizzing rather than pain
- Worse at rest — sitting or lying down
- Relieved by movement, at least while you keep moving
- Worse in the evening or at night
That last point is what makes it a sleep problem rather than a leg problem. Many people also have periodic limb movements during sleep, which fragment the night without waking them fully — so a partner may be the one who notices.
Why it becomes more common in midlife
Prevalence rises with age and is roughly twice as high in women as in men. Several midlife factors converge:
- Iron deficiency, which is the most important and most fixable — see below
- Hormonal change, which appears to influence the dopamine pathways involved, though the mechanism is not fully established
- Sleep deprivation, which lowers the threshold for symptoms
- Medications commonly started in this decade, including some antidepressants and antihistamines
The iron connection — the point of this article
Restless legs is strongly associated with low brain iron, and iron replacement improves symptoms in people who are deficient. This matters enormously in perimenopause, where heavy periods make iron depletion very common.
Two specifics that determine whether you get the right answer:
- Ask for ferritin, not just haemoglobin. Iron stores fall long before anemia appears, and a normal full blood count does not rule out deficiency.
- The threshold used for restless legs is higher than the general one. Sleep guidelines commonly consider iron treatment when ferritin is below roughly 75 µg/L in this context — a level that would be reported as "normal" on most laboratory reports. If you are told your iron is fine, ask what the actual number was.
That single detail is the reason many women with restless legs are told nothing is wrong. See low ferritin in perimenopause and heavy periods in perimenopause.
What else to check
- Kidney function, since restless legs is common in kidney disease
- Thyroid function; see perimenopause versus thyroid
- Vitamin B12 and folate
- Blood glucose, since diabetes-related neuropathy can mimic it
- A medication review — this resolves more cases than people expect
Medications that commonly worsen or trigger it: many antidepressants (SSRIs, SNRIs, mirtazapine), sedating antihistamines including those in over-the-counter sleep aids, some anti-nausea drugs, and antipsychotics. If your symptoms started within weeks of a new prescription, say so — an alternative often exists.
What helps without medication
- Treat the iron deficiency if present. This is the highest-value step and can resolve it entirely.
- Regular moderate exercise, though not intense exercise close to bedtime, which can worsen symptoms.
- Consistent sleep timing. Sleep deprivation makes it worse, which creates a loop worth breaking; see perimenopause sleep problems.
- Reduce caffeine, alcohol, and nicotine — all three are recognized aggravators, and alcohol in particular is a common evening trigger; see alcohol in midlife.
- Stretching, massage, and warm or cool compresses, which help some people in the moment.
- Pneumatic compression devices have some supporting evidence.
- Get up and walk during an episode rather than lying there fighting it.
Prescription options, and one important caution
Medications exist for moderate to severe restless legs, and the recommended approach has changed.
Alpha-2-delta ligands — gabapentin, gabapentin enacarbil, and pregabalin — are now generally favoured as first-line drug treatment. Gabapentin has the additional benefit of reducing hot flashes, which makes it a reasonable candidate in menopause specifically; see non-hormonal prescription options for hot flashes.
Dopamine agonists were the mainstay for years, and current guidance has moved away from them as first-line because of augmentation — a phenomenon in which symptoms become progressively worse over time, start earlier in the day, and spread to other body parts. Augmentation is treatment-caused and difficult to reverse, and it is the reason this shift happened. If you are already on one of these medications and your symptoms have worsened or started earlier in the day, that is a specific thing to raise rather than a reason to increase the dose.
This is a genuinely useful thing to know before a prescription, because it is not always explained.
Does HRT help?
There is no established evidence that hormone therapy treats restless legs, and it should not be started for it. Indirectly, treating night sweats and improving sleep may reduce how much the symptoms affect you. Treat the iron and the sleep directly rather than expecting hormones to solve it.
How to raise it
Describe the four features, because that is what a clinician needs to hear:
"Most evenings I get an uncomfortable urge to move my legs when I sit down, it's worse at night, and walking is the only thing that relieves it. It's costing me an hour of sleep most nights. My periods have been heavy — could we check ferritin specifically, and could you tell me the actual number rather than whether it's in range?"
That last clause is the one that matters, given the higher threshold used in this condition.

Iron is the first thing to check here and the connection is under-known — see low ferritin in perimenopause, when iron is not the answer, how to actually take iron, and, if you donate blood, the iron problem nobody flags. The full test list is in which tests to ask for.
One caution on iron. Take it for a confirmed deficiency, not on suspicion — iron overload is harmful, and this is one of the few places where guessing does damage rather than nothing. Ask for ferritin rather than starting a supplement, and if it is low, ask why — see low ferritin in perimenopause, how to actually take iron and our free blood test sheet.
