Restless Legs Syndrome 101: Causes, Symptoms, Diagnosis and Treatment

Restless Legs Syndrome (RLS) is a disorder of the nervous system that causes an overwhelming need to move the legs. People with RLS often feel an uncomfortable crawling, itching, or pulling sensation deep inside their legs. These symptoms are often stronger in the evening and at night, which can make it very difficult to fall or stay asleep, which can lead to constant tiredness, trouble concentrating, and a low mood during the day. The good news is that RLS can be easily diagnosed and managed. In this blog, we’ll explore all about RLS to help you identify and address the condition. Let’s start with the basics.

What is Restless Legs Syndrome?

Restless Legs Syndrome is classified as a neurological condition that disrupts the normal functioning of the nervous system, leading to discomfort and difficulty in staying still. It is often linked to imbalances in brain chemicals that regulate movement, particularly dopamine. In some cases, RLS can run in families, pointing to a genetic influence, while in others it develops alongside medical conditions such as iron deficiency or kidney disease. The intensity of RLS can vary widely, from mild and occasional symptoms to severe and persistent episodes that interfere with daily activities. Unlike temporary restlessness or fatigue, RLS follows a specific pattern and tends to worsen during periods of inactivity, which is why medical recognition is important for effective management.

What Causes Restless Legs Syndrome?

RLS can arise from different factors. In some people, it occurs without any underlying medical issue, while in others it is linked to health conditions or external influences. Below are the main causes:

Primary RLS

Primary RLS, also called idiopathic RLS, occurs without an associated medical condition. It often appears gradually and tends to worsen with age. Family history plays an important role here, as research shows that the condition can be inherited, particularly when symptoms begin before the age of 40. Scientists believe that changes in the way the brain’s dopamine system functions may be involved. Dopamine is a chemical messenger that controls muscle movement, and any disruption in its pathways can contribute to the sensations and urge to move seen in RLS.

Secondary RLS

Secondary RLS develops as a result of other medical issues or physiological changes. Some of the most common factors include:

Iron deficiency: Iron is vital for dopamine activity in the brain. Low iron levels, even without full anaemia, are strongly linked to worsening RLS symptoms.

Chronic kidney disease: Patients with kidney failure or those undergoing dialysis are at higher risk of RLS due to altered iron metabolism and other chemical imbalances.

Diabetes: Nerve damage caused by long-term diabetes can trigger or worsen RLS symptoms.

Neurological conditions: Disorders such as Parkinson’s disease affect dopamine pathways, which can contribute to RLS.

Pregnancy: Many women develop RLS during pregnancy, especially in the last trimester. Although symptoms often subside after delivery, the condition can significantly disturb sleep during this time.

Medications That May Aggravate RLS

Certain medicines have been found to intensify or trigger symptoms in people already prone to RLS. These include:

Antihistamines used for allergies and colds

Some antidepressants

Certain antipsychotics

Medications for nausea

Doctors usually review ongoing prescriptions when evaluating patients with RLS to identify if medicines may be worsening symptoms.

Lifestyle and Environmental Triggers

Even when no underlying illness is present, lifestyle and environmental factors can play a role in triggering or worsening RLS symptoms. Some of the common triggers include:

Caffeine: Found in tea, coffee, chocolate, and energy drinks, it can overstimulate the nervous system.

Alcohol: Known to disrupt normal sleep cycles and intensify night-time symptoms.

Lack of sleep or irregular sleep schedule: Sleep deprivation not only worsens RLS but also reduces the body’s ability to cope with symptoms.

Stress: Emotional stress can heighten the perception of discomfort, making symptoms more noticeable.

What are the Symptoms of Restless Legs Syndrome?

The symptoms of RLS are often described as unusual, uncomfortable sensations that make it difficult to stay still. They usually follow a specific pattern and can vary from mild to severe. The most common symptoms include:

Unpleasant sensations in the legs: Many people describe feelings such as crawling, tingling, pulling, itching, or burning deep within the legs. These are not usually painful but can be extremely bothersome and hard to ignore.

Strong urge to move: The discomfort creates an irresistible need to move the legs. Relief may come from walking, stretching, or shaking the legs, but it is only temporary and the sensations often return once movement stops.

Symptoms linked to rest: Periods of sitting or lying down, such as during travel, relaxation, or bedtime, tend to trigger or worsen the sensations, making it difficult to rest.

Evening or night-time worsening: Symptoms usually intensify later in the day and are often at their worst during the night. This worsening pattern is considered a key feature of RLS.

Sleep disturbances: Because symptoms interfere with the ability to fall asleep or stay asleep, many people struggle with insomnia. The lack of rest often leads to daytime fatigue, difficulty concentrating, irritability, and reduced productivity.

Symptoms in other areas: Although the legs are most commonly affected, similar sensations may sometimes occur in the arms or, less frequently, other parts of the body.

How is Restless Legs Syndrome Diagnosed?

There is no single test that can confirm RLS. Instead, doctors rely on a detailed assessment of symptoms, medical history, and specific investigations to rule out other possible causes. A structured approach ensures that the condition is identified accurately.

Medical History: Diagnosis often begins with a thorough discussion about symptoms. Doctors ask when the sensations first started, how often they occur, and how they affect sleep and daily activities. The timing of symptoms is important, as RLS usually worsens in the evening or during periods of rest. A review of family history is also useful, since RLS can run in families. Alongside this, lifestyle habits and current medications are examined, as some medicines or stimulants can worsen the condition.

Physical and Neurological Examination: A physical examination helps rule out visible problems such as poor circulation or joint issues. Neurological checks are performed to identify signs of peripheral neuropathy, spinal problems, or other nerve-related conditions that may mimic RLS. Simple strength, reflex, and sensation tests are often included to assess the health of the nervous system.

Blood Tests: Laboratory tests play an important role in detecting underlying contributors. Low iron levels are strongly linked to RLS, so doctors frequently request ferritin tests to measure iron stores in the body. Depending on the case, other tests may be done to assess kidney function, blood sugar (for diabetes), thyroid function, or vitamin deficiencies such as B12 and folate. Identifying these conditions is essential, as treating them can improve or even resolve RLS symptoms.

Sleep Studies: When symptoms significantly disturb rest, a sleep study (polysomnography) may be recommended. During this test, patients are monitored overnight, and recordings are taken of leg movements, brain activity, breathing patterns, and sleep quality. Although not always required for diagnosis, sleep studies are especially useful if another sleep disorder such as sleep apnoea is suspected alongside RLS.

Ruling Out Other Conditions: Finally, part of the diagnostic process involves excluding other conditions that could cause similar symptoms. Disorders such as neuropathy, arthritis, muscle cramps, and venous insufficiency can mimic the sensations of RLS. By carefully ruling these out, doctors can confirm the diagnosis and recommend treatment that specifically addresses RLS rather than a different underlying condition.

What are the Treatment Options for Restless Legs Syndrome?

Treatment is focused on reducing discomfort, improving sleep quality, and addressing any underlying causes. Depending on the severity, treatment can include the following:

Iron Supplementation: Iron deficiency is a common contributor to RLS. When blood tests reveal low iron or ferritin levels, oral iron supplements are usually recommended. In cases where oral supplements are not effective or poorly tolerated, intravenous iron may be administered. Correcting iron deficiency can significantly reduce the intensity of symptoms and improve sleep.

Dopaminergic Medicines: These medications help regulate dopamine activity in the brain, which is often disrupted in RLS. They are particularly effective in reducing the urge to move and easing uncomfortable leg sensations. Doctors carefully adjust doses to maximise relief while minimising side effects.

Anti-Seizure Medicines: Certain medications originally developed to treat epilepsy are prescribed for RLS because they calm overactive nerve signals. These drugs are often chosen for patients who experience painful or burning sensations in the legs and can be effective in reducing night-time symptoms.

Sleep Medications: For individuals whose sleep is significantly disrupted, sedatives or sleep-inducing medicines may be used. While these do not directly address leg discomfort, they can help patients achieve restorative sleep and reduce daytime fatigue.

Pain Relievers: Mild pain or discomfort associated with RLS may be managed with over-the-counter pain relievers. In severe cases, doctors may prescribe stronger medications, but these are used cautiously due to the risk of dependence or side effects.

Lifestyle Adjustments: Daily habits and routines can significantly influence symptom severity. Effective strategies include:

Maintaining a consistent sleep schedule and creating a calm bedtime environment.

Engaging in moderate physical activity such as walking, stretching, or yoga.

Limiting caffeine, alcohol, and tobacco, which can exacerbate symptoms.

Using relaxation techniques such as warm baths, massages, or applying heat and cold packs to the legs.

Supportive Therapies: Additional non-drug therapies can help manage symptoms and improve quality of life. These include:

Compression devices: Special socks or pneumatic devices that improve circulation and reduce leg discomfort.

Cognitive behavioural therapy (CBT): Helps manage insomnia and stress associated with RLS.

What are Some Coping Strategies for Managing the Symptoms?

Living with RLS can be challenging, but adopting specific strategies can help reduce discomfort, improve sleep, and make daily life more manageable. These coping methods are most effective when combined with medical treatment and guidance from a healthcare professional.

1. Establish a Regular Sleep Routine: Maintaining consistent sleep and wake times helps regulate the body’s internal clock and can reduce the severity of symptoms at night. Creating a calm, quiet, and comfortable sleep environment also supports better rest.

2. Stay Physically Active: Regular, moderate exercise such as walking, stretching, yoga, or swimming can help relieve leg discomfort. Gentle activity before bed can ease symptoms, but overexertion or intense workouts late in the evening may worsen them.

3. Use Leg Comfort Techniques: Simple measures can provide temporary relief from uncomfortable sensations:

Stretching the legs before bedtime

Massaging or rubbing the legs

Applying warm baths, heating pads, or cold packs to the affected areas

4. Limit Stimulants: Reducing or avoiding caffeine, alcohol, and nicotine can prevent symptoms from worsening, particularly in the evening.

5. Manage Stress: Stress and anxiety often intensify RLS symptoms. Practising relaxation techniques such as deep breathing, meditation, gentle yoga, or mindfulness exercises can help calm the nervous system and reduce discomfort.

6. Plan for Restless Nights: For nights when symptoms are severe, consider strategies such as getting out of bed to walk or stretch, using a supportive chair for leg movement, or listening to calming music. Having a plan can reduce frustration and improve sleep quality.

7. Track Triggers: Keeping a symptom diary can help identify patterns and triggers, such as certain foods, medications, or periods of inactivity. Recognising these factors allows for targeted adjustments that may reduce symptom frequency or intensity.

When Should You Consult a Doctor?

Seeking medical advice is important to ensure accurate diagnosis and effective management of RLS. Consider consulting a doctor in the following situations:

Persistent or worsening symptoms: If the sensations in your legs occur frequently, increase in intensity, or make it difficult to rest or sleep, professional evaluation is necessary. Early intervention can prevent chronic sleep disturbances and daytime fatigue.

Impact on daily life: When RLS begins to affect work performance, social activities, or emotional wellbeing, it is a sign that professional guidance is needed. Even moderate symptoms can gradually reduce overall quality of life.

Suspected underlying health conditions: RLS can be linked to issues such as iron deficiency, kidney disease, diabetes, or neurological disorders. Consulting a doctor helps identify and treat these contributing conditions effectively.

Need for targeted medical treatment: Self-care strategies such as lifestyle adjustments may not always be sufficient. A healthcare professional can recommend appropriate medications, supplements, or therapies, and monitor their effectiveness and safety.

Uncertainty about symptoms: If you are unsure whether your leg discomfort is RLS or another condition, a medical evaluation can clarify the cause and guide the best approach to management.

Timely consultation ensures proper diagnosis, relief from symptoms, and improved sleep and daily functioning.
