Sign 5. Restless Leg Syndrome: The Unsettling Symptom of Iron Deficiency
Restless leg syndrome (RLS) is more than just discomfort in your legs. It’s a neurological disorder characterized by an irresistible urge to move the legs. Iron deficiency has been associated with increased prevalence of RLS.
Iron plays an important role in producing dopamine, a neurotransmitter that helps regulate muscle movements. When your iron levels are low, dopamine production might decrease, potentially leading to conditions like RLS.
Those with RLS describe the sensation as crawling, creeping, pulling, or uncontrollable twitching. These sensations often occur during the night, leading to poor sleep quality.
Like other symptoms, restless legs can often be overlooked or mistaken for overexertion or muscle fatigue. But if these sensations persist and disrupt your sleep, it might be due to an iron deficiency. (5)
