“The symptoms of Guillain-Barré syndrome (GBS) can be alarming, because they usually come on suddenly and lead to weakness (sometimes paralysis) of the arms and legs. Fortunately, Guillain-Barré syndrome is rare and often clears up after prompt medical treatment, though it may take years for symptoms to go away completely. After hospitalization, physical therapy can contribute to a favorable GBS prognosis.
As GBS progresses, it can cause alarming symptoms, including total paralysis, difficulty chewing and swallowing, and trouble breathing. In virtually every case, however, GBS paralysis and other symptoms resolve within days to weeks. Statistically, around 70% of people who experience Guillain-Barré paralysis will fully recover their muscle strength, function and sensation. As the nerves begin to heal, physical rehabilitation can greatly improve the prognosis.
According to the U.S. Centers for Disease Control and Prevention (CDC), approximately 3,000 to 6,000 people develop the syndrome each year. The risk of developing GBS increases with age, and people older than 50 face the highest risk of developing the condition. You cannot eliminate your risk of developing Guillain-Barré syndrome, since the exact cause remains unknown. However, certain types of food poisoning can trigger it, so you can reduce your risk by thoroughly cooking poultry and other foods, as well as scrubbing fresh fruits and vegetables.”
