a person trying to sleep with restless leg syndrome

Restless Leg Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterized by an uncontrollable urge to move the legs, usually due to uncomfortable, unpleasant sensations. These sensations typically occur in the evening or during periods of inactivity, such as lying down or sitting for extended times. RLS affects a significant portion of the population and can lead to difficulty in falling and staying asleep, thereby impacting the overall quality of sleep and daily life.


The exact cause of RLS is still not entirely understood, but it is thought to involve dopamine, a brain chemical that plays a key role in controlling muscle movement. This disorder may have a genetic component, as it often runs in families, particularly when it starts at a younger age. Other contributing factors include iron deficiency, kidney failure, and peripheral neuropathy. Certain medications can also exacerbate RLS symptoms. Pregnancy, especially in the last trimester, may trigger the condition, but it usually resolves after delivery.


Symptoms of RLS include the compelling need to move the legs, often accompanied by uncomfortable sensations described as itching, crawling, pulling, or throbbing. These symptoms typically worsen during the night and can severely disrupt sleep, leading to daytime fatigue, mood swings, and impaired concentration. In many cases, moving the legs or walking can temporarily relieve these discomforts.


Diagnosing RLS can be challenging, as there's no specific test for it. At Sonoran Sleep Center, our approach involves a thorough review of medical history, symptoms, and a physical examination. In some cases, blood tests may be conducted to rule out other conditions like iron deficiency. A key part of the diagnosis is determining the impact of symptoms on sleep quality and daily activities.


Treatment for RLS is tailored to the individual, depending on the severity of symptoms and their impact on sleep and daily life. If an underlying condition is identified, such as iron deficiency, treating it may relieve RLS symptoms. Medications used to treat RLS include drugs that increase dopamine in the brain, benzodiazepines, opioids, and anticonvulsant drugs, which can help control symptoms. However, these medications can have side effects and might not be suitable for everyone, especially in the long term.


Lifestyle changes and home remedies can also be effective in managing RLS. Regular physical activity, maintaining a regular sleep schedule, avoiding caffeine and alcohol, and quitting smoking can help reduce symptoms. For some, leg massages, hot baths, or heating pads provide temporary relief.


At Sonoran Sleep Center, our team of experts is dedicated to providing comprehensive care for RLS. We understand the challenges posed by this condition and work closely with patients to develop effective management strategies, combining medical treatments with lifestyle modifications. Our goal is to improve not only the quality of sleep but also the overall quality of life for individuals living with RLS.
