What is Restless Leg Syndrome and why do I have it?

What Is Restless Legs Syndrome (RLS)?

Restless Legs Syndrome (RLS), also known as Willis-Ekbom Disease, is a neurological condition that causes an irresistible urge to move the legs. This often happens when you’re resting or trying to sleep, typically in the evening or at night. Along with the strong urge to move, many people experience uncomfortable sensations, such as:

  • Tingling
  • Crawling
  • Itching
  • Aching
  • Throbbing

These sensations are typically relieved by moving the legs, but they often return when you stop. As a result, RLS can interfere with sleep, leading to fatigue, irritability, and even anxiety. For some, the condition may worsen over time, making it even more challenging to manage.

Why Do I Have Restless Legs?

The exact cause of RLS isn’t fully understood, but there are several factors that may contribute to or trigger the condition. Here are some of the most common reasons:

1. Genetic Factors

Restless Legs Syndrome can run in families, suggesting a genetic component. If you have a close relative with RLS, you may be more likely to develop it yourself. Studies indicate that certain gene mutations may be involved in the development of the disorder, though more research is needed.

2. Iron Deficiency

Low iron levels in the brain are one of the most common contributors to RLS. Iron is essential for dopamine production, a neurotransmitter involved in controlling movement. When iron levels are insufficient, dopamine function may be impaired, which can lead to the sensations experienced in RLS.

3. Dopamine Imbalance

Dopamine, a chemical messenger in the brain, helps control muscle movements. In people with RLS, there may be a disruption in dopamine production or receptor function, which leads to the sensations and urges to move the legs.

4. Pregnancy

Pregnant women, particularly in the third trimester, are more likely to experience RLS. Hormonal changes, along with increased blood volume and changes in iron levels, can trigger or worsen RLS symptoms. Fortunately, RLS often improves after childbirth.

5. Chronic Conditions

Certain chronic conditions are linked to RLS, including:

  • Peripheral neuropathy: Damage to the nerves in the limbs can cause sensations of tingling, pain, and discomfort, contributing to RLS symptoms.
  • Kidney disease: People with kidney failure or those on dialysis often experience RLS due to low iron levels or toxins in the body.
  • Diabetes: High blood sugar levels can damage nerves and lead to symptoms similar to RLS.
  • Parkinson’s disease: This neurodegenerative disease is associated with low dopamine levels, which can exacerbate RLS symptoms.
  • Fibromyalgia: This chronic pain condition can coexist with RLS, leading to increased discomfort.

6. Medications

Certain medications can trigger or worsen RLS symptoms. These include:

  • Antihistamines (e.g., for allergies)
  • Antidepressants (especially SSRIs)
  • Antipsychotics
  • Cold medications (some contain decongestants) If you think a medication may be contributing to your RLS symptoms, consult your doctor for advice on alternatives or adjustments.

7. Lifestyle Factors

Certain lifestyle factors can also play a role in triggering RLS:

  • Caffeine: High caffeine intake can aggravate RLS symptoms, especially when consumed in the evening.
  • Alcohol: Drinking alcohol, particularly close to bedtime, can interfere with sleep and increase RLS discomfort.
  • Lack of Physical Activity: Sedentary behavior can contribute to muscle tension and poor circulation, exacerbating RLS symptoms.
  • Stress: Mental and emotional stress can make RLS symptoms worse. Finding ways to manage stress can help reduce the severity of symptoms.

How to Manage and Treat Restless Legs

While RLS can be frustrating, there are several strategies and treatments that can help manage the condition and alleviate symptoms:

1. Lifestyle Adjustments

  • Exercise Regularly: Mild physical activity like walking, swimming, or yoga can improve circulation and reduce RLS symptoms.
  • Avoid Triggers: Reducing caffeine and alcohol intake, especially before bedtime, may help prevent or lessen symptoms.
  • Create a Relaxing Bedtime Routine: Establish a calm and consistent sleep schedule. Consider relaxation techniques like deep breathing, meditation, or a warm bath before bed to ease tension.

2. Iron Supplements

If your RLS is linked to iron deficiency, your doctor may recommend iron supplements or dietary changes to increase your iron intake. Foods rich in iron, such as red meat, leafy greens, and legumes, may also help.

3. Medications

For more severe cases, doctors may prescribe medications to help manage RLS symptoms. These could include:

  • Dopamine agonists (e.g., pramipexole or ropinirole) to help improve dopamine function
  • Iron supplements if low iron is identified as a factor
  • Anti-seizure medications (e.g., gabapentin) to reduce nerve-related symptoms
  • Benzodiazepines (e.g., clonazepam) or other sleep aids to help with insomnia caused by RLS

4. Compression and Massaging Devices

Compression sleeves or massage devices like the PureRelief Pro™ can provide relief for people with RLS by improving circulation, reducing muscle tension, and providing soothing pressure to the legs. These non-invasive tools can be used at night to help you relax and sleep more comfortably. 

5. Warm or Cold Therapy

Some people find relief from RLS symptoms by using heating pads or cold compresses on their legs. Heat can relax muscles and promote circulation, while cold therapy may numb discomfort. Products like the PureRelief Plus™ can assist in managing symptoms through gentle heat throughout the night. 

Final Thoughts

Restless Legs Syndrome may be disruptive, but it is manageable with the right approach. If you’re experiencing symptoms of RLS, such as an uncontrollable urge to move your legs or discomfort while resting, consult a healthcare provider. They can help determine the underlying cause and develop a treatment plan tailored to your needs.

Remember, you don’t have to suffer through sleepless nights and discomfort. There are solutions available that can help you get the restful sleep you deserve and manage your symptoms effectively.
