What is Restless Leg Syndrome?

Do you ever feel an uncontrollable urge to move your legs—especially at night? If so, you might be experiencing symptoms of Restless Leg Syndrome (RLS), a common but often misunderstood neurological condition that affects sleep and overall quality of life.

In this post, we’ll explore what Restless Leg Syndrome is, what causes it, and how it can be managed so you can rest easier.

Understanding Restless Leg Syndrome

Restless Leg Syndrome, also known as Willis-Ekbom Disease, is a condition that causes uncomfortable sensations in the legs. Restless Leg Syndrome is often described as uncomfortable tingling, crawling, pulling, itching, or throbbing in the legs.

These sensations typically occur when you’re at rest—sitting or lying down—and are only relieved by moving your legs. Symptoms are usually worse in the evening or at night, making it difficult to fall asleep or stay asleep.

What Causes RLS?

The exact cause of RLS is not fully understood, but it is believed to involve an imbalance of dopamine, a chemical in the brain that helps regulate muscle movement. Some common factors that may contribute to or worsen RLS include:

• Genetics: RLS can run in families, especially if symptoms begin before age 40.

• Iron deficiency: Low iron levels in the brain may be linked to RLS.

• Chronic conditions: Such as kidney failure, diabetes, or peripheral neuropathy.

• Pregnancy: Especially in the third trimester—though symptoms often resolve after delivery.

• Certain medications: Including some antihistamines, antidepressants, and antipsychotics.

• Caffeine, alcohol, and nicotine: These can aggravate symptoms in some people.

How is RLS Diagnosed?

There’s no single test for RLS. Diagnosis is usually based on a description of your symptoms, when and how often the symptoms occur, medical and family history, and blood tests to check for iron deficiency or other potential causes. If your sleep is affected, a sleep study may be recommended to rule out other sleep disorders like sleep apnea.

Treatment Options

Treatment for RLS depends on the severity of symptoms and underlying causes. Common strategies include:

Lifestyle Changes

• Avoiding caffeine, alcohol, and tobacco

• Establishing a regular sleep routine

• Doing moderate daily exercise

• Taking warm baths or using heating pads on your legs

Medical Treatment

• Iron supplements (if deficiency is detected)

• Prescription medications that affect dopamine, nerve pain, or muscle activity

It’s important to talk with a healthcare provider before starting any treatment plan to ensure it's appropriate for your needs.

When to Seek Help

If restless legs are keeping you up at night or interfering with your daily life, don’t ignore the signs. Restless Leg Syndrome is a treatable condition, and the sooner you seek help, the sooner you can find relief and get back to better sleep.
