Guillain-Barré syndrome (GBS) often starts following a preceding infection, particularly a respiratory infection or gastroenteritis (food poisoning).
Understanding the Onset of GBS
While the exact cause of GBS isn't fully understood, it's strongly linked to the body's immune response after an infection. Here's a breakdown:
- Preceding Infections: GBS typically appears a few days or weeks after an individual experiences a respiratory infection or gastroenteritis.
- Immune Response: The immune system, in its attempt to fight off the infection, mistakenly attacks the body's own nerve cells.
- Rare Instances: In rarer situations, GBS can occur after a vaccination.
In summary, GBS usually begins following an infection, triggering an autoimmune reaction that affects the peripheral nerves.
