What is considered the biggest danger associated with Guillain-Barré Syndrome?

Guillain-Barré Syndrome (GBS) is a rare neurological disorder where the body's immune system mistakenly attacks the peripheral nerves. One of the most significant dangers associated with GBS is the potential for respiratory failure due to muscle weakness. As the condition progresses, it can lead to paralysis of the diaphragm and other muscles involved in respiration, resulting in respiratory arrest. This can be life-threatening and often requires urgent intervention, such as mechanical ventilation.

While the other options present serious concerns, they are not the primary focus when discussing the greatest risk in GBS. Seizures and cardiac arrest can occur in various medical conditions but are not typical complications directly associated with GBS. Fatal infections may arise due to prolonged immobility or weakness, but the most immediate and dangerous threat is the inability to breathe effectively.
