Restless legs syndrome


Restless legs syndrome (RLS) is a neurological disorder that causes an uncomfortable urge to move the legs. It may also affect the arms and other parts of the body. Symptoms can range from mild to severe, and can be made worse when sitting or lying still for a long period of time. It can interfere with sleep and quality of life, leading to daytime fatigue and sleepiness. Treatment options include lifestyle changes, medications, and physical therapy.


The primary symptom of Restless Legs Syndrome (RLS) is an irresistible urge to move the legs. This urge is usually accompanied by uncomfortable feelings such as tingling, tugging, or burning in the legs. Other symptoms of RLS include:

  • Unwanted twitching or jerking of the legs
  • Difficulty falling or staying asleep
  • Pain or discomfort in the legs that is temporarily relieved by moving them
  • Sensations of crawling, itching, or pulling deep within the legs
  • Worsening of symptoms in the evening or at night
  • Frequent leg movements during sleep, resulting in a disturbed sleep


There is no exact cause of Restless Legs Syndrome (RLS) but it is believed to be linked to a disruption in the balance of dopamine and other neurochemicals in the brain. Other factors that may contribute to the condition include genetics, iron deficiency, nerve damage, certain medications, kidney problems, pregnancy and alcohol use.

Risk factors

The risk factors for Restless Leg Syndrome (RLS) include:

  1. Genetics: RLS tends to run in families, with studies showing that up to 50 percent of people with RLS have a close relative who has or had RLS.
  2. Age: RLS is more common in people over age 40 although it can affect people of all ages.
  3. Gender: Women are more likely to have symptoms of RLS than men.
  4. Pregnancy: Pregnant women are twice as likely to experience RLS than women who are not pregnant, particularly during the third trimester.
  5. Medications: Certain medications, including some used for treating high blood pressure, Parkinson’s disease, and antidepressants, can cause or worsen RLS symptoms.
  6. Iron deficiency: Low iron levels in the body can cause RLS symptoms, particularly in people ages 50 and younger.
  7. Chronic diseases: People with kidney failure, diabetes, and rheumatoid arthritis are at higher risk of developing RLS.
  8. Sleep deprivation: Getting too little sleep or interrupted sleep may increase the risk of having RLS.
  9. Substance abuse: People who use tobacco, alcohol, or drugs are more likely to develop RLS.


Restless legs syndrome (RLS) is typically diagnosed through a physical examination and a detailed medical history. During a physical examination, a doctor will assess signs and symptoms in order to determine whether or not RLS is present. A detailed medical history is also important, as it allows the doctor to gain a better understanding regarding the patient’s condition and the potential causes of their symptoms. Additionally, certain tests such as blood and urine analysis may be required in order to rule out other conditions that could be causing the patient’s symptoms. Finally, it is important to keep track of the patient’s diet, physical activity and sleep habits, as these are all factors that could contribute to the onset and severity of the condition.


Restless Legs Syndrome (RLS) is a common medical condition that is characterized by an irresistible urge to move the legs, usually accompanied by uncomfortable sensations such as tingling, aching, burning, or a feeling of restlessness. There are four main types of Restless Legs Syndrome, each with distinct characteristics:

  1. Primary RLS: Also known as idiopathic RLS, this type is the most common and can be found in both children and adults. It is caused by a malfunction in the body’s dopamine system and has no identifiable cause. Symptoms include an irresistible urge to move the legs, often worsened by inactivity or by lying down to sleep.
  2. Secondary RLS: This type is caused by an underlying medical condition or other factors, including medications, alcohol, iron deficiency, or chronic kidney failure. The symptoms of secondary RLS can be more severe than those of the primary form.
  3. Periodic Limb Movement Disorder (PLMD): This is a sleep-related disorder that is similar to RLS, but is associated with involuntary leg movements during sleep. It is more common in people with RLS.
  4. Willis-Ekbom Disease (WED): This is a chronic neurological condition that is similar to RLS, but is usually more severe and persistent. It is often linked to a malfunction in the body’s dopamine system and is more common in people with a family history of RLS. Symptoms can include an uncontrollable urge to move the legs, as well as trouble sleeping and uncomfortable sensations in the legs.


Treatment options for Restless Legs Syndrome vary depending on the severity and underlying cause. Generally, lifestyle and home remedies are used for mild cases. Some of these measures include:

  • Avoiding caffeine, nicotine, and alcohol
  • Exercising regularly
  • Maintaining a regular sleep schedule
  • Maintaining a healthy diet
  • Taking warm baths or massaging the legs
  • Using hot or cold packs
  • Trying relaxation techniques, such as meditation, yoga, and tai chi

In more severe cases, medications may be prescribed to help control the uncomfortable sensations and improve sleep. These medications include:

  • Dopaminergic medications, such as levodopa/carbidopa and dopamine agonists
  • Pain relievers, such as gabapentin and pregabalin
  • Opioids
  • Anticonvulsants
  • Muscle relaxants
  • Benzodiazepines
  • Iron supplements

In some cases, lifestyle and home remedies may not be enough to manage Restless Legs Syndrome symptoms. In these cases, doctors may recommend treatment with a device called a transcutaneous electrical nerve stimulation (TENS) machine. This device sends a low-level electrical signal to the affected area to help reduce the symptoms.


In order to reduce the risk of Restless Legs Syndrome, the following measures can be taken:

  • Regular exercise: Regular physical activity can help to minimize symptoms of RLS and improve overall health.
  • Healthy Diet: Eating nutrient-rich foods such as fruits, vegetables, and lean proteins can help support restful sleep and reduce RLS symptoms.
  • Avoid Caffeine and Alcohol: Caffeine and alcohol can worsen RLS symptoms, so it is important to limit their intake.
  • Avoid Smoking: Smoking has been linked to increased risk of RLS, so it is important to quit or avoid smoking.
  • Practice Relaxation Techniques: Mindful meditation, yoga, and deep breathing can reduce stress levels that can worsen RLS.
  • Take Iron Supplements: Iron supplements can help those with low levels of ferritin which can be a contributing factor to RLS.
  • Seek Professional Help: If symptoms persist it is important to seek the advice of a medical professional.

Gender differences?

Yes, there are gender-specific differences in the presentation and management of Restless Legs Syndrome (RLS). Generally, women are more likely to be diagnosed with RLS than men, and their symptoms tend to be more severe. Men are less likely to report symptoms, even when they exist. Additionally, women tend to have more difficulty controlling their symptoms with lifestyle changes, such as exercise and relaxation techniques. Women’s symptoms may also be more resistant to treatment with medications, such as dopamine agonists. Finally, some studies have indicated that pregnancy may increase the severity of symptoms, but this is still an area that requires further research.


Nutrition plays an important role in the management of Restless Legs Syndrome (RLS). It is important to ensure that the body is receiving adequate amounts of essential vitamins and minerals, such as magnesium, iron, and B vitamins, which have been linked to RLS. Additionally, eating a balanced, nutrient-dense diet full of a variety of plant-based proteins, healthy fats, and complex carbohydrates can help to regulate the body’s dopamine levels, which may help to decrease the symptoms of RLS. It is also important to avoid caffeine and alcohol, as these can worsen symptoms. Finally, staying hydrated by drinking plenty of water is important.

Physical Activity

Physical activity can often have a positive effect on Restless Legs Syndrome (RLS). Moderate activity can help to reduce tension, which can help to reduce the severity of the symptoms of RLS. Additionally, exercise can help to improve circulation, which can help the body to better transport nutrients to the nerve cells, which can help to prevent the uncomfortable sensations associated with RLS. Exercise can also help to increase the production of endorphins, which can help to reduce pain and discomfort. Additionally, physical activity can help to improve sleep quality, which can in turn help to reduce the severity of RLS symptoms.
