Restless Leg Syndrome During Pregnancy: Causes, Symptoms, and Relief

Restless Leg Syndrome (RLS) is a common condition characterized by an irresistible urge to move the legs, often accompanied by uncomfortable sensations. For pregnant women, RLS can be particularly challenging, affecting sleep quality and overall well-being. In this blog we will explore the causes, symptoms, and various relief strategies for managing restless leg syndrome during pregnancy.

Understanding Restless Leg Syndrome in Pregnancy:

  • Prevalence of RLS during pregnancy: RLS is more prevalent in pregnant women, affecting approximately 20% of them. It usually begins or worsens in the third trimester.
  • Onset and progression of symptoms: RLS symptoms may appear for the first time during pregnancy or intensify if the woman already had the condition.
  • Hormonal changes and their impact on RLS: Hormonal fluctuations, including an increase in estrogen and progesterone, are believed to contribute to the development or worsening of RLS symptoms during pregnancy.

Symptoms and Challenges of Restless Legs in Pregnancy:

  • Sensations experienced in the legs: Pregnant women with RLS commonly describe sensations such as crawling, tingling, or itching in their legs.
  • Increased severity in the evenings and at night: RLS symptoms tend to worsen during periods of rest or inactivity, especially in the evening and at night.
  • Sleep disturbances and their effects on pregnant women: RLS can disrupt sleep, leading to fatigue and daytime sleepiness, which can impact the well-being of pregnant women.

Causes and Triggers of Restless Leg Syndrome during Pregnancy:

  • Hormonal fluctuations during pregnancy: Changes in hormone levels, particularly estrogen and progesterone, may contribute to the development or exacerbation of RLS symptoms.
  • Iron deficiency and its connection to RLS: Iron plays a crucial role in the normal functioning of the brain and nervous system. Pregnant women are more prone to iron deficiency, and low iron levels have been linked to RLS.
  • Circulation issues and their role in symptom development: Pregnancy-related changes in blood flow and circulation may contribute to RLS symptoms by affecting nerve function and triggering discomfort in the legs.

Relief Strategies for Restless Leg Syndrome during Pregnancy:

  • Regular exercise and its benefits: Engaging in light to moderate exercise, such as walking or swimming, can help reduce RLS symptoms by promoting circulation and releasing endorphins.
  • Warm baths and massages for temporary relief: Soaking in a warm bath or receiving a leg massage can provide temporary relief from RLS discomfort and promote relaxation.
  • Iron supplementation and its potential impact: If iron deficiency is identified, healthcare providers may recommend iron supplements to correct the deficiency, potentially alleviating RLS symptoms.
  • Medications and their cautious use: In severe cases, when other measures fail, healthcare providers may consider prescribing medications that are safe for use during pregnancy. However, the risks and benefits should be carefully evaluated, and medications should only be used under medical supervision.
  • Lifestyle adjustments for better sleep hygiene: Adopting good sleep hygiene practices, such as maintaining a regular sleep schedule, creating a comfortable sleep environment, and using relaxation techniques, can help improve sleep quality for pregnant women with RLS.

Seeking Medical Guidance for Restless Leg Syndrome in Pregnancy:

  • Consulting with healthcare providers: It is important for pregnant women experiencing RLS symptoms to discuss them with their healthcare providers for proper evaluation and guidance.
  • Evaluation of symptoms and underlying causes: Healthcare providers can assess the severity of RLS symptoms, evaluate any underlying causes such as iron deficiency, and develop an individualized treatment plan.
  • Individualized treatment plans and recommendations: Healthcare providers will recommend the most appropriate treatment options based on the severity of symptoms, underlying causes, and the stage of pregnancy, ensuring the safety and well-being of both the mother and the baby.


Restless Leg Syndrome during pregnancy can be an uncomfortable and disruptive condition, affecting sleep quality and overall well-being. Understanding the causes and triggers, as well as implementing appropriate relief strategies, can greatly improve the management of RLS symptoms. It is essential for pregnant women to seek guidance from healthcare providers to ensure safe and effective treatment options. With proper care and support, it is possible to find relief and enjoy a more comfortable pregnancy journey.
