Symptoms

Guillain-Barre syndrome often begins with tingling and weakness starting in the feet and legs and spreading to the upper body and arms. Some people notice the first symptoms in the arms or face. As Guillain-Barre syndrome progresses, muscle weakness can turn into paralysis.

Symptoms of Guillain-Barre syndrome may include:

  • A pins and needles feeling in the fingers, toes, ankles or wrists.
  • Weakness in the legs that spreads to the upper body.
  • Unsteady walk or not being able to walk or climb stairs.
  • Trouble with facial movements, including speaking, chewing or swallowing.
  • Double vision or inability to move the eyes.
  • Severe pain that may feel achy, shooting or cramplike and may be worse at night.
  • Trouble with bladder control or bowel function.
  • Rapid heart rate.
  • Low or high blood pressure.
  • Trouble breathing.

People with Guillain-Barre syndrome usually experience their most significant weakness within two weeks after symptoms begin.

Types

The symptoms of Guillain-Barre syndrome can vary based on the type. Guillain-Barre syndrome has several forms. The main types are:

  • Acute inflammatory demyelinating polyradiculoneuropathy (AIDP), the most common form in North America and Europe. The most common sign of AIDP is muscle weakness that starts in the lower part of the body and spreads upward.
  • Miller Fisher syndrome (MFS), in which paralysis starts in the eyes. MFS also is associated with an unsteady walk. MFS is less common in the U.S. but more common in Asia.
  • Acute motor axonal neuropathy (AMAN) and acute motor-sensory axonal neuropathy (AMSAN) are less common in the U.S. But AMAN and AMSAN are more frequent in China, Japan and Mexico.

When to see a doctor

Call your healthcare professional if you have mild tingling in your toes or fingers that doesn't seem to be spreading or getting worse. Seek emergency medical help if you have any of these serious symptoms:

  • Tingling that started in your feet or toes and is now moving up your body.
  • Tingling or weakness that's spreading quickly.
  • Trouble catching your breath or shortness of breath when lying flat.
  • Choking on saliva.

Guillain-Barre syndrome is a serious condition that requires immediate hospitalization because it can worsen quickly. The sooner treatment is started, the better the chance of a complete recovery.

Causes

The exact cause of Guillain-Barre syndrome isn't known. It usually appears days or weeks after a respiratory or digestive tract infection. Rarely, recent surgery or vaccination can trigger Guillain-Barre syndrome.

In Guillain-Barre syndrome, your immune system — which usually attacks only invading organisms — begins attacking the nerves. In AIDP, the nerves' protective covering, known as the myelin sheath, is damaged. The damage prevents nerves from transmitting signals to your brain, causing weakness, numbness or paralysis.

Guillain-Barre syndrome may be triggered by:

  • Most commonly, an infection with campylobacter, a type of bacteria often found in undercooked poultry.
  • Influenza virus.
  • Cytomegalovirus.
  • Epstein-Barr virus.
  • Zika virus.
  • Hepatitis A, B, C and E.
  • HIV, the virus that causes AIDS.
  • Mycoplasma pneumonia.
  • Surgery.
  • Trauma.
  • Hodgkin lymphoma.
  • Rarely, influenza vaccinations or childhood vaccinations.
  • COVID-19 virus.

Risk factors

Guillain-Barre syndrome can affect all age groups, but the risk increases as you age. It's also slightly more common in males than females.
