Causes of Restless Legs Syndrome
Restless Legs Syndrome is a central nervous system disorder which may have a genetic basis. It is also possible that RLS may be a brain chemical disorder.
Psychiatric conditions or stress may exacerbate RLS, but they do not cause RLS.
Restless Legs Syndrome can be brought on by other conditions, including:
An underlying medical problem – such as diabetes mellitus, kidney disease, Parkinson's Disease, or rheumatoid arthritis.
Iron deficiency anemia – the way the body metabolizes iron and certain proteins in the brain may be related to restless legs syndrome.
Pregnancy – many women experience RLS in the last months of pregnancy, possibly as a result of an iron deficiency. Left untreated, the symptoms often go away after delivery.
Particular medications – medications including tricyclic antidepressants, anti-nausea, and some cold and allergy drugs may increase or trigger RLS symptoms.
Varicose veins – when vein valves fail, the backward flow of blood pools and stagnates in the veins, which can lead to aching, throbbing, cramping and fatigue in the legs.
Effects of Restless Legs Syndrome
Restlessness – An inability to sit still because the leg sensations are too annoying or painful
Insomnia – Difficulty falling asleep or staying asleep
Daytime sleepiness – RLS can keep you from getting a restful night's sleep, resulting in exhaustion during the day
