Learn More About Restless Leg Syndrome
If you have restless leg syndrome, or RLS, you likely have an incredible and irresistible urge to move your legs. Although not painful, the condition is uncomfortable and bothersome, particular as it often affects you at night while you are trying to sleep.
In fact, according to Medscape, about 85 percent of people who have restless leg syndrome, have periodic movements of sleep, whereby they have involuntary backward flexing of the foot occurring on average every 30 seconds and lasting up to five seconds throughout their sleep.
Causes of RLS
At this time, unfortunately, the specific causes of RLS are not known. While research is still being conducted, one theory is that abnormal brain chemicals related to your neurotransmitters that help to control movement may be a causal factor. Another theory is that areas of the central nervous system abnormalities that controls automatic movements may be involved in the condition.
Secondary restless leg syndrome may be a result of another medical condition. Two of the most common medical conditions suggested to be linked to restless legs syndrome are iron-deficiency anemia (or having a abnormally low blood count) and peripheral neuropathy ( a condition often associated with diabetes that involves damage to the nerves in the legs, arms, and especially in the feet.)
It’s important to know though that in many cases the cause of RLS in patients is undiagnosed.
