Guillain-Barre syndrome is where the immune system begins attacking the nerves. There isn’t one particular cause, but it usually develops when the immune system overreacts to a prior infection or threat to the body. Many people who have gotten Guillain-Barre were fighting off the flu or another infection and then develop GBS.
When I looked it up, I saw the most severe cases- inability to swallow, needing physical therapy for months, being hospitalized with plasma transfusions. It all seemed quite overwhelming and I prayed that my husband wouldn’t continue to lose neurological function.
