The Connection Between Restless Leg Syndrome & Varicose Veins

Restless legs syndrome (RLS) and varicose veins are common medical conditions that can cause discomfort and disrupt daily life. While they may seem unrelated at first glance, evidence suggests a potential connection between them.

Understanding this relationship can help you better manage symptoms and seek appropriate treatment. 

Below, we will explore the symptoms of restless legs syndrome and varicose veins, discuss the potential connection between the two conditions, highlight shared risk factors, and address particular varicose vein treatments scientifically proven to improve the symptoms of restless legs syndrome.

Can varicose veins cause restless leg syndrome?

Varicose veins are a type of chronic venous insufficiency disorder. According to one study, 98% of participants with restless legs syndrome also had chronic venous disorders (CVD). 

While further research is ongoing and necessary, several theories explain this relationship.

For one, varicose veins occur due to impaired leg circulation, which causes blood pooling and inflammation that can lead to overactive nerves, possibly contributing to developing or worsening restless leg syndrome symptoms. Additionally, the discomfort and pain associated with varicose veins can disrupt sleep, exacerbating restless leg symptoms.

What’s the connection between restless legs syndrome and varicose veins?

A few key connections between restless legs syndrome and varicose veins are shared risk factors and symptoms. Here are some common shared risk factors between varicose veins and restless legs syndrome:

• Hormonal changes: Pregnancy, for example, causes many hormonal fluctuations to occur. These changes can weaken the vein walls and valves, leading to the formation of varicose veins, and they are also more likely to experience restless legs syndrome symptoms. However, it’s worth noting that restless legs syndrome symptoms often resolve after giving birth.
• Genetics: Certain studies indicate that restless legs and varicose veins have a hereditary genetic component. If you have a family history of either condition, you may be at an increased risk of developing both.
• Obesity: Excess weight puts added pressure on the veins and can impair blood flow, leading to the development of varicose veins. Similarly, obesity has been associated with the onset and severity of restless legs symptoms. 
• Underlying venous disease: Venous disease is a common condition that potentially leads to varicose veins or restless legs syndrome. Both conditions share many of the same symptoms, including pain, cramping, and discomfort in the legs.
• Poor circulation: When blood flow is impaired, it can lead to fluid buildup in the legs, triggering restless legs syndrome symptoms. Poor circulation is a known cause of varicose veins. 

Will treating varicose veins cure restless leg syndrome (RLS)?

Treating varicose veins may alleviate some symptoms of restless leg syndrome, but it is unlikely to cure the condition completely. For instance, proactive steps to address varicose vein symptoms can improve blood flow, reducing discomfort, including RLS symptoms. 

However, RLS is a complex neurological disorder whose exact cause is not fully understood. It is important to consult a healthcare professional specializing in venous and sleep disorders to develop an appropriate treatment plan for managing RLS symptoms.

Effective varicose vein treatments to relieve symptoms of restless legs syndrome

While there is no direct cure for RLS, certain varicose vein treatments can improve blood flow and reduce venous insufficiency, possibly relieving RLS symptoms. Four effective varicose vein treatments that can potentially help manage RLS symptoms include:

• Sclerotherapy: A treatment commonly used for small varicose veins and spider veins, sclerotherapy has shown positive outcomes in reducing symptoms of Restless Leg Syndrome. In one study involving 113 patients receiving sclerotherapy, 98% claimed a decrease in their RLS symptoms.
• Endovenous laser ablation (EVLA): According to a research study, it was found that 80% of participating patients with moderate to very severe RLS experienced a significant reduction in their symptoms after undergoing Endovenous Laser Ablation (EVLA) treatment.
• Radiofrequency Ablation (RFA): A minimally invasive procedure commonly used to treat varicose veins, RFA was shown in one study to reduce RLS symptoms in individuals with severe RLS significantly. Remarkably, one of the patients even reported a complete disappearance of RLS symptoms after a radiofrequency ablation procedure.
• Compression stockings: Frequently used for individuals with varicose veins to improve blood circulation in the legs, a 2012 study discovered that wearing compression stockings can effectively relieve the symptoms associated with restless leg syndrome in those affected by the condition.

While these treatments can potentially alleviate some RLS symptoms, it is important to note that each individual responds differently. RLS is a complex condition, and its management often involves a combination of approaches, including lifestyle changes, medication, and other therapies.
