Guillain-Barré Syndrome: Symptoms, Causes & Treatments

Weakness

When we move, electric signals will travel from your brain to the peripheral nerves via the spinal cord to trigger the operation of your limb muscles. However, in Guillain-Barré syndrome, your immune system might damage these nerves. As a result, your muscles cannot receive signals and respond accordingly. That’s why weakness might happen, especially in your legs, arms, and some associated areas. This symptom tends to progress quickly and worsen in a few hours or days. You might feel it on both sides of your body, also known as symmetric. [3]
