Patients who have Guillain-Barre syndrome may remain in the hospital for several months and recovery may take as long as a year or more. Most patients with GBS recover completely, but some have residual weakness, numbness, and occasional pain. A small number of patients are unable to resume their normal daily activities or occupation.
Fewer than 5% of GBS patients die. Those fatalities usually result from cardiovascular or respiratory complications. Death resulting from chronic inflammatory demyelinating polyradicalneuropathy (CIDP) is rare.
