Quick answer
What is Guillain-Barré syndrome?
Guillain-Barré syndrome is a rare but serious condition in which the immune system mistakenly attacks the peripheral nerves. It often follows a few weeks after an infection (such as a gut or respiratory infection).
- How it is treated: Guillain-Barré syndrome is treated in hospital, often with close monitoring (including of breathing) as it can progress rapidly.
- Self-care: During recovery, rehabilitation and physiotherapy to regain strength and function are central, alongside support for fatigue and any lasting symptoms.
- When to seek help: Seek urgent care (999/A&E) for rapidly worsening weakness or numbness spreading up the body, difficulty walking, or any difficulty breathing or swallowing — Guillain-Barré syndrome is a medical emergency.
What it is
Guillain-Barré syndrome is a rare but serious condition in which the immune system mistakenly attacks the peripheral nerves. It often follows a few weeks after an infection (such as a gut or respiratory infection). Typically it causes numbness, tingling and weakness that starts in the feet and hands and spreads upwards over hours to days, sometimes progressing to severe weakness and, in serious cases, affecting the muscles used for breathing and swallowing. Because it can worsen quickly and affect breathing, it is a medical emergency requiring hospital admission. Most people recover, though recovery can take weeks to many months, and some are left with lasting effects.
How it is treated
Guillain-Barré syndrome is treated in hospital, often with close monitoring (including of breathing) as it can progress rapidly. Specific treatments that calm the immune attack — such as immunoglobulin given into a vein, or a blood-cleaning procedure (plasma exchange) — can speed recovery. Supportive care is crucial: help with breathing if needed, prevention of complications, pain relief, and physiotherapy and rehabilitation to regain strength and function. Most people improve, but recovery is often gradual, and rehabilitation over months plays a big part. Early recognition and treatment give the best outcomes.
