Causes and Risk Factors of Restless Legs Syndrome

By identifying the root causes, individuals can adopt more effective strategies to alleviate symptoms and improve their quality of life.

For an in-depth look into what triggers RLS, including genetic, environmental, and physiological factors, read our comprehensive article on Cause of Restless Legs Syndrome.

Genetic Factors

  • Genetics play a significant role in RLS, often running in families.
  • Specific gene variations, like the MEIS1 gene, are linked to increased risk and severity.

Iron Deficiency

  • Iron deficiency, even without anemia, can cause RLS.
  • Iron is essential for dopamine production, which controls muscle movement.
  • Low brain iron levels reduce dopamine activity, contributing to RLS symptoms.

Iron and Dopamine Connection

  • Dopamine production requires iron.
  • Low brain iron disrupts dopamine production, causing RLS symptoms.
  • The substantia nigra, a brain region for dopamine production, is affected by iron levels.

Chronic Diseases

  • Kidney disease, diabetes, and peripheral neuropathy increase RLS risk.
  • These conditions can cause nerve damage or affect iron metabolism.

Kidney Disease

  • Chronic kidney disease leads to iron deficiency and nerve damage.
  • Dialysis patients are at higher risk due to significant iron loss.

Diabetes

  • Poorly managed diabetes can cause peripheral neuropathy, damaging nerves and worsening RLS.
  • Blood sugar control is crucial for diabetic patients with RLS.

Medications

  • Antidepressants, antipsychotics, and some antihistamines can trigger or worsen RLS.
  • These medications affect dopamine pathways or iron metabolism.

Pregnancy

  • Third-trimester pregnancy often triggers or worsens RLS due to hormonal changes, increased blood volume, and iron deficiency.
  • Symptoms usually resolve postpartum, but managing iron levels during pregnancy is crucial.

Hormonal Changes

  • Hormonal fluctuations, especially in estrogen, can influence dopamine and exacerbate RLS.

Increased Blood Volume

  • Increased blood volume during pregnancy dilutes iron levels, triggering RLS.
  • Careful monitoring of iron intake is essential.

Lifestyle Factors

  • Poor sleep hygiene, excessive caffeine or alcohol consumption, and a sedentary lifestyle can contribute to RLS.

Sleep Hygiene

  • Irregular sleep schedules and excessive screen time before bed can worsen RLS.
  • Good sleep habits are essential for managing symptoms.

Caffeine and Alcohol

  • Excessive caffeine and alcohol can interfere with sleep and increase nerve activity, worsening RLS.

Nervous System Disorders

  • Parkinson's disease, multiple sclerosis, and spinal cord injuries can cause or worsen RLS.

Parkinson's Disease

  • Degeneration of dopamine-producing neurons in Parkinson's is linked to RLS.
  • Dopamine deficiency in both conditions suggests a shared pathway.

Multiple Sclerosis

  • MS damages nerve coverings, disrupting signals and causing RLS symptoms.

Environmental Factors

  • Prolonged inactivity, especially in the evening or during long journeys, can trigger or worsen RLS.
  • Regular movement and avoiding long periods of immobility help manage symptoms.

Prolonged Inactivity

  • Sitting for long periods, like during flights, can exacerbate RLS.
  • Taking breaks to walk and stretch can alleviate discomfort.
