Guillain-Barre syndrome is a rare auto-immune disorder. It is a serious disease, in which the immune system attacks healthy nerve cells in the peripheral nervous system. This causes muscle weakness, numbness, tingling sensation in the extremities and eventual paralysis. The condition is typically triggered by an infectious illness like gastroenteritis or a respiratory infection. There are multiple types of Guillain-Barre syndrome, such as acute inflammatory demyelinating polyradiculoneuropathy and Miller Fisher syndrome.
