What causes restless leg syndrome?
The cause of restless leg syndrome is unknown in most people. However, restless leg syndrome has been associated with
- iron deficiency and anemia,
- nerve disease,
- polyneuropathy (which can be associated with hypothyroidism, heavy metal toxicity, toxins, and many other conditions),
- other hormone diseases such as diabetes, and
- kidney failure (which can be associated with vitamin and mineral deficiency).
Some drugs and medications have been associated with restless leg syndrome including:
- H2-histamine blockers (such as ranitidine [Zantac] and cimetidine [Tagamet]), and certain antidepressants (such as amitriptyline [Elavil, Endep]).
Occasionally, restless leg syndrome run in families. Recent studies have shown that restless leg syndrome appears to become more common as a person ages. Also, poor venous circulation of the legs (such as with varicose veins) can cause restless leg syndrome.
