Restless legs are a common complaint that often causes restlessness and discomfort, especially in the evening or at night. Many people recognize the feeling of restless legs, but when these complaints become more extensive and chronic, we refer to it as restless legs syndrome (RLS). This syndrome can affect daily life through sleep problems and fatigue during the day.
What is restless legs?
Restless legs refer to an unpleasant and often uncontrollable feeling in the legs, usually accompanied by the urge to move them. Restless legs syndrome (RLS) is a medical movement disorder where these symptoms occur, especially when at rest. The difference is that ordinary restless legs occur occasionally, while RLS is a chronic condition that often flares up in the evening and at night, disrupting daily functioning.
Symptoms of restless legs
The complaints of restless legs consist of itching, cramps, pain, and a restless feeling in the legs. These symptoms worsen especially at rest and in the evening, making movement the primary way to find relief. The urge to constantly move the legs often leads to sleep problems, resulting in fatigue and loss of concentration during the day.
Causes of restless legs
The exact cause of restless legs is still unclear and partly unknown. Heredity plays an important role, as familial predisposition is common. Triggers such as iron deficiency or chronic diseases can exacerbate complaints. Additionally, there is a connection with Periodic Limb Movement Disorder (PLMD), a related sleep disorder that can occur alongside RLS.
What is Periodic Limb Movement Disorder (PLMD)?
PLMD causes involuntary, automatic movements of the arms and legs during sleep. These brief movements often result in poor sleep quality and lead to fatigue during the day. Although PLMD and restless legs symptoms can overlap, PLMD is a separate disorder with its own characteristics and diagnostics.
When to see a doctor?
If symptoms persist or worsen, it is wise to consult a doctor for an accurate diagnosis. The doctor will inquire about the nature of the symptoms and investigate possible triggers. A timely diagnosis helps in finding effective treatments to reduce the complaints.
Treatment and tips for restless legs
Treatment often focuses on addressing any underlying causes such as iron deficiency and making lifestyle adjustments. Exercise, the use of warm or cold compresses, and improving sleep hygiene can provide relief. Relaxation techniques also help to reduce complaints. Although restless legs may not always be completely cured, the symptoms can be well managed with these methods.
