What happens if restless legs syndrome is not treated?

Restless legs syndrome causes uncomfortable sensations and an urge to move, often when resting or trying to sleep. Repeated movement can delay sleep, cause frequent waking, and reduce restorative sleep. The result may be tiredness, irritability, difficulty concentrating, and reduced ability to manage normal activities safely.

The condition may be linked with iron deficiency anaemia or chronic kidney disease. Leaving symptoms unexplored can mean a treatable contributor is missed. Symptoms can also change over time, with discomfort becoming more frequent or appearing earlier in the day.

Book a GP consultation if restless legs are affecting sleep, work, travel, or quality of life. Your clinician can review medicines, health conditions, sleep patterns, and diet. A blood test may help check iron levels and other clues to an underlying cause. Treatment is tailored to the findings rather than based on the leg sensations alone.

While waiting, keep a regular sleep routine, reduce caffeine if it worsens symptoms, and try gentle walking or stretching when the urge starts. Do not start iron supplements without advice, because excess iron can be harmful and the correct product depends on your results.

Arrange prompt medical advice if symptoms are new, steadily worsening, or accompanied by marked daytime sleepiness. Seek urgent help for sudden one-sided leg swelling and pain, chest pain, or shortness of breath, as these are not typical restless legs symptoms and may indicate another problem.

Ask: Could iron deficiency or kidney disease be contributing? Should I have a blood test? Could any of my medicines worsen the symptoms? Which sleep and movement treatments are suitable, and when should we review progress?
