1. What exactly is Restless Legs Syndrome, and why does it show up during pregnancy?
Restless Legs Syndrome is a condition that causes an irresistible urge to move your legs—often accompanied by tingling, crawling, or achy sensations. During pregnancy, this can happen due to hormonal shifts, changes in dopamine levels, or nutritional deficiencies like low iron or folate. Many women who’ve never had RLS experience it for the first time during pregnancy, especially in the third trimester.
2. What does RLS feel like? How do I know if that’s what I’m experiencing?
Many women describe RLS as a pulling, crawling, or itchy sensation deep in their legs—especially when they’re resting or lying down. If moving your legs helps temporarily relieve the feeling and it tends to worsen at night, there’s a good chance you’re dealing with RLS. If you’re unsure, talk to your provider to explore a proper diagnosis.
3. Is RLS dangerous to me or my baby?
The good news is that RLS itself isn’t harmful to your baby. But it can severely affect your sleep, which in turn impacts your energy, mood, and overall health. Some studies suggest that unmanaged RLS may contribute to longer labors or an increased risk of cesarean delivery—so it’s definitely worth addressing.
4. What causes RLS during pregnancy?
RLS during pregnancy is most commonly linked to low iron levels, dopamine imbalances in the brain, and changing estrogen levels. In some cases, even low Vitamin D levels or mild thyroid dysfunction can contribute. Since each pregnancy is different, your provider may recommend blood tests to look for underlying causes.
5. What are some natural or lifestyle remedies that can help with RLS?
Plenty of non-medication strategies can offer relief. Try keeping a consistent sleep routine, avoiding caffeine, staying well-hydrated, and doing gentle daily exercise like walking or prenatal yoga. Warm baths, leg stretches, and compression socks can also help soothe symptoms. Everybody is different, so try a few methods and see what works best for you.
6. Can I take supplements or medication to treat RLS while pregnant?
Iron supplements are commonly recommended if your iron levels are low—your provider can check this with a blood test. However, many medications used to treat RLS outside of pregnancy haven’t been well-studied in pregnant women and may carry risks. Always speak with your healthcare provider before starting any new supplement or medication during pregnancy.
7. How can I sleep better if RLS keeps me awake at night?
Start with good sleep hygiene: keep your room cool and dark, avoid screens before bed, and stick to a relaxing bedtime routine. Elevate your legs, use pillows to support a comfortable position, and stretch gently before sleep. If RLS symptoms still keep you up, talk to your provider about next steps.
8. Will RLS go away after I have my baby?
For most women, yes. Nearly all pregnancy-related RLS symptoms resolve within days or weeks after delivery. That’s because hormone levels and nutrient needs start to normalize. It may take a bit of time, but for many new moms, the restless legs do settle down—just in time for those middle-of-the-night feedings!
9. When should I call my doctor about RLS symptoms?
If your symptoms are disrupting your sleep, affecting your mood, or just making pregnancy harder to enjoy, please talk to your provider. They can check your iron and vitamin levels and help you explore safe treatment options. Don’t wait—good rest is too important for both you and your baby.
10. Is there anything unusual I should watch out for with RLS symptoms?
If you ever notice severe leg cramps, swelling in just one leg, or pain that doesn’t improve with movement, it’s important to call your provider right away. These may not be RLS and could signal another issue like a blood clot. When in doubt, always check in—it’s the safest choice for you and your baby.
