Restless Legs Syndrome (RLS), also known as Willis-Ekbom Disease, is a neurological condition that causes an uncontrollable urge to move the legs—often accompanied by uncomfortable sensations. These symptoms typically occur in the evening or at night, interfering with sleep and leading to ongoing tiredness, poor concentration, and reduced quality of life.
At IP Diagnostics, we support patients with accurate assessment, appropriate testing, and practical treatment options to help manage RLS and improve sleep.
What Is Restless Legs Syndrome?
RLS is characterised by an overwhelming urge to move the legs, usually triggered by periods of rest or inactivity. People often describe the sensation as crawling, tingling, burning, or itching deep within the legs—though it can also affect the arms. Movement temporarily relieves the discomfort, but symptoms usually return once stillness resumes.
The symptoms tend to worsen in the evening or during the night, often making it difficult to fall or stay asleep. RLS is considered a sensorimotor disorder because it involves both sensory symptoms and the need for motor (movement) response.
Symptoms of RLS
- Strong, often irresistible urge to move the legs
- Tingling, creeping, or pulling sensations in the legs
- Symptoms that start or worsen during periods of rest or inactivity
- Relief from movement (e.g. walking, stretching)
- Symptoms that are worse in the evening or at night
- Difficulty falling asleep or staying asleep
Chronic sleep disruption from RLS can lead to daytime fatigue, reduced alertness, and a negative impact on mental wellbeing.
What Causes Restless Legs Syndrome?
In many cases, RLS is idiopathic (no identifiable cause), but several factors are known to contribute or increase risk:
- Low iron levels or abnormal iron handling in the brain
- Chronic conditions such as kidney disease, diabetes, or Parkinson’s disease
- Pregnancy, especially in the third trimester
- Certain medications, including antidepressants and antihistamines
- Family history of RLS
- Sleep deprivation or irregular sleep patterns
Identifying and treating any underlying cause is an important step in managing symptoms.
Diagnosing RLS at IP Diagnostics
There is no single test for RLS, but an accurate diagnosis begins with a thorough clinical review of your symptoms, medical history, and sleep patterns. At IP Diagnostics, we provide:
- Specialist clinical consultations to evaluate your symptoms in detail
- In-home overnight sleep studies, if needed, to assess for related conditions like periodic limb movement disorder (PLMD) or sleep apnoea
- Iron studies or blood tests, arranged through your GP or care team if iron deficiency is suspected
Our expert physiologists and consultant sleep physicians work together to ensure you receive a clear diagnosis and personalised treatment recommendations.
Treatment Options for Restless Legs Syndrome
There are a range of approaches to managing RLS, depending on the severity and underlying cause. These may include:
- Iron supplementation, if low iron levels are identified
- Medications that alter dopamine or nerve signalling, especially in moderate to severe cases
- Lifestyle changes such as regular exercise, improved sleep hygiene, and reducing caffeine or alcohol intake
- Stretching routines or relaxation techniques to reduce symptoms in the evening
At IP Diagnostics, we’ll help guide you through the options and support you in making changes that reduce symptoms and improve your sleep quality.
