What Causes Restless Leg Syndrome?

Restless leg syndrome is a condition in which your legs experience an unpleasant sensation causing an irresistible urge to move them – often during sleep or when trying to fall asleep or when at rest, either lying or sitting down. By moving the legs, the uncomfortable sensation eases and goes away temporarily. Restless leg syndrome may also occur in the arms. This condition can disrupt sleep routines, most frequently during the evening or early part of the night, making it hard to fall asleep and stay asleep.

What Causes Restless Leg Syndrome (RLS)?

In most cases of restless leg syndrome, no cause can be found. Primary RLS refers to this condition when no cause can be found. However, studies have shown that primary restless leg syndrome tends to run in families, which may suggest that there may be a genetic link that increases the chance of developing the condition.

Secondary RLS is RLS that is caused by an underlying condition or as a side effect from certain medications.

Some of the conditions and diseases that are associated with RLS include:
* Iron deficiency
* Anemia
* Peripheral neuropathy
* Nerve disorders
* Kidney failure
* Diabetes
* Rheumatoid arthritis
* Parkinson’s disease
* Thyroid problems
* Sleep apnea
* Narcolepsy
* Obesity
* Varicose veins
* Stress
* Pregnancy

Help for Restless Leg Syndrome (RLS)

Because there is no cure for RLS, the primary aim of treatment is to relieve symptoms, increase the amount and quality of sleep, and treat or correct any underlying condition that may cause RLS. Some drugs and medications that are associated with RLS include caffeine, alcohol, antihistamine blockers, anti-seizure medicines, anti-nausea medicines, and certain antidepressants.
If symptoms are mild, implementing a few lifestyle changes such as eliminating caffeine, stopping smoking, getting better sleep and more exercise may be quite beneficial. In more severe cases where RLS interferes with sleep or daily activities, certain medications are effective. Other treatment options that may be considered include electric nerve stimulation, oral magnesium supplementation, acupuncture, warm or cold baths.
