Restless leg syndrome
Overview
Restless leg syndrome is a neurological disorder characterized by an uncontrollable urge to move the legs, typically accompanied by uncomfortable sensations like tingling, burning, or crawling feelings. These symptoms usually worsen during periods of rest or inactivity, particularly in the evening or at night.
Common Causes
Restless leg syndrome can be triggered by several common factors. Iron deficiency is one of the most frequent causes, as low iron levels affect nerve and muscle function in the legs. Pregnancy often brings on these symptoms due to hormonal changes and increased blood volume. Certain medications like antihistamines, antidepressants, and anti-nausea drugs can worsen the condition. Lifestyle factors such as excessive caffeine intake, alcohol consumption, and lack of regular exercise may also contribute to symptoms. Additionally, sitting or lying still for extended periods can trigger episodes, which is why symptoms often worsen in the evening or at bedtime.
Severity Levels
Mild: Symptoms occur occasionally and cause minor sleep disruption. You may experience brief periods of leg discomfort that can be relieved by movement or stretching.
Moderate: Symptoms happen several times per week and begin to interfere with sleep quality and daily activities. The urge to move becomes more persistent and harder to ignore.
Severe: Symptoms occur nightly or almost nightly, significantly disrupting sleep and affecting your ability to function during the day. The condition may impact work, social activities, and overall quality of life.
Medical Attention
Contact your healthcare provider if leg discomfort regularly disrupts your sleep or daily activities. Seek medical attention if symptoms worsen over time or if you experience severe sleep deprivation affecting your quality of life. Schedule an appointment if over-the-counter remedies and lifestyle changes don't provide adequate relief after a few weeks.
