GBS can cause symptoms that last for as little as a few weeks, or go on for several months. Most people recover fully from GBS, but some people have nerve damage that does not go away. In rare cases, people have died of GBS, usually from not being able to breathe due to weakness of their breathing muscles.How to diagnose GBS?
GBS can be difficult to diagnose, especially in its earlier phases. The symptoms vary between people, and they are similar to the symptoms of other neurological conditions. An EMG may be required to help diagnose GBS. Initially, the doctor will check if the weakness occurs on both sides of the body, as this is a typical a feature of GBS.What causes Guillain-Barre syndrome (GBS)?
