What can be done to prevent the condition?

Most cases of Guillain-Barré syndrome cannot be prevented. Following safer sex guidelines may prevent some cases that are triggered by sexually transmitted diseases, such as HIV. Illegal drugs, such as heroin, should not be used.

What are the long-term effects of the condition?

About 95% of those with Guillain-Barré syndrome survive. About 75% completely recover. For some, mild weakness or chronic pain will continue throughout life. GBS can be fatal if it causes problems with breathing. Full recovery can be expected if symptoms go away not long after they appear. This usually happens within 3 weeks.

Weakness and decreased sensation can cause contractures. Contractures occur because muscles become thick and tight when they are not used. They shrink and shorten, causing joint deformities. There can also be loss of movement in the affected areas.

Blood clots may develop because of loss of motion and muscle contractions. Blood-thinning medicines, such as warfarin or heparin, can be given to help prevent blood clots. There is an increased risk of infection, including pneumonia.

What are the risks to others?

Guillain-Barré syndrome is not contagious and poses no risk to others. If GBS is triggered by an infection, the infection itself may be contagious.
