Unraveling the Mysteries of Restless Leg Syndrome: Causes, Symptoms, and Treatment Options

Imagine the frustration of an uncontrollable urge to move your legs, often accompanied by uncomfortable sensations, just as you’re trying to relax or fall asleep. This is the reality for millions of people worldwide who suffer from Restless Leg Syndrome (RLS), a complex disorder that can significantly impact quality of life. In this article, we’ll dive deep into the potential causes of RLS, explore common symptoms, and discuss effective treatment options, including the connection between RLS and varicose veins.

 

Understanding Restless Leg Syndrome

Restless Leg Syndrome is a disorder characterized by an irresistible urge to move the legs, usually accompanied by unpleasant sensations like tingling, aching, or crawling. RLS affects an estimated 10-15% of the U.S. population, with women being more likely to experience symptoms than men. The condition can occur at any age but is most common in middle-aged and older adults. RLS can significantly impact quality of life, causing sleep disturbances, fatigue, and difficulty concentrating.

 

Potential Causes of Restless Leg Syndrome

While the exact cause of RLS still being studies, several factors have been identified as potential contributors. Genetic factors play a role, with up to 50% of RLS cases having a family history of the condition. Up to 80% of people who have varicose veins also have Restless Leg Syndrome.  

 

Other causes include iron deficiency anemia have also been linked to RLS, as iron is crucial for proper dopamine function in the brain. Pregnancy, particularly in the third trimester, can trigger RLS symptoms, which often resolve after delivery. Chronic medical conditions such as Parkinson’s disease, kidney disease, and diabetes may also increase the risk of developing RLS. Certain medications, including antidepressants and antihistamines, have been known to exacerbate RLS symptoms. 

 

The Varicose Vein Connection

Recent studies have shown that varicose veins, a common condition characterized by enlarged, twisted veins, may contribute to the development of RLS. Varicose veins occur when the valves in the veins become weakened or stretched, causing the valve to not close properly.  This allows blood to fall back down and stretch the vein walls causing varicosities.  This impaired circulation can lead to nerve compression, which may trigger the uncomfortable sensations and urge to move associated with RLS.

 

Dr. David Verebelyi, a leading vein specialist at Colorado Skin & Vein, explains, “Many patients are surprised to learn that their restless legs may be connected to underlying vein issues but 80% of people with venous reflux also have RLS symptoms.  63% of patients who receive treatment for their vein issues have significant or complete relief of their RLS symptoms.”

 

Several studies support the link between venous insufficiency and RLS. A study published in the journal Phlebology found that patients with RLS had a higher prevalence of varicose veins compared to those without RLS. Another study in the journal Dermatologic Surgery reported that treating varicose veins with sclerotherapy resulted in significant improvement of RLS symptoms.

 

Diagnosing and Treating Restless Leg Syndrome

Diagnosing RLS involves a thorough evaluation of symptoms and medical history. The International Restless Legs Syndrome Study Group has established five diagnostic criteria, including an urge to move the legs, onset or worsening of symptoms during rest, relief with movement, and occurrence primarily in the evening or night.

 

Treatment for RLS often begins with lifestyle changes, such as regular exercise, maintaining good sleep hygiene, and avoiding triggers like caffeine and alcohol. Sometimes medications, including dopaminergic agents like ropinirole and pramipexole, and gabapentin, may be prescribed to manage symptoms. However, for patients with RLS and varicose veins, addressing the underlying venous issues can be a critical step in finding relief.  All patients with RLS should rule out venous reflux as the cause.

 

Dr. Verebelyi notes, “At Colorado Skin & Vein, we take a comprehensive approach to treating RLS, addressing underlying venous issues when present to provide optimal relief for our patients.”

 

Vein treatments such as sclerotherapy, which involves injecting a solution to seal off damaged veins, and endovenous ablation, which uses heat to close off damaged veins, have been shown to improve RLS symptoms in the vast majority of patients.  Colorado Skin & Vein offers state-of-the-art vein treatments in a comfortable, spa-like setting, with a focus on personalized care and patient satisfaction.




Getting Permanent Relief from RLS

Restless Leg Syndrome is a complex condition with multiple potential causes, including genetic factors, vascular issues,  iron deficiency, and underlying medical conditions. The link between RLS and varicose veins is an important consideration in diagnosing and treating this disorder. By identifying and addressing contributing factors like venous insufficiency, patients can find significant relief from the disruptive symptoms of RLS.

 

Dr. Verebelyi encourages those struggling with restless legs to seek help: “If you’re struggling with restless legs, know that you’re not alone and that effective treatments are available. Don’t hesitate to talk to your doctor or a vein specialist to start your journey towards better sleep and improved quality of life.”
