Restless legs syndrome during pregnancy

Pregnancy can change iron needs, sleep, circulation, and comfort in the legs. Restless legs syndrome presents as an urge to move with crawling, pulling, tingling, or aching sensations that improve temporarily when you move. Iron deficiency anaemia may contribute, but leg discomfort in pregnancy has other causes too. A clinician should distinguish this pattern from swelling, cramping, nerve symptoms, or a problem affecting one leg. Mention how far along you are and whether symptoms are new, worsening, or preventing sleep.

Tell your midwife, obstetric clinician, or GP if symptoms interfere with rest. They may use your history and a blood test to consider iron status and other explanations. Do not begin, increase, or stop iron supplements or other medicines without pregnancy-specific advice. Gentle walking, calf stretching, a warm—not hot—bath, massage, and a regular sleep routine may help. Support comfortable hydration and activity according to your maternity guidance.

Seek urgent maternity or emergency advice for sudden one-leg swelling, warmth, redness, or significant pain, especially with chest pain or breathlessness. Seek prompt review for fainting, severe weakness, heavy bleeding, or a major change in your general health. Persistent difficulty sleeping should be raised at routine pregnancy care even when no urgent warning sign is present.

Ask which blood tests are suitable, whether your prenatal supplement provides enough iron for your needs, and which medicines or comfort measures are safe. Ask how to tell restless legs from a clot or another pregnancy complication.
