Answer

A study by Anandan et al indicated that in hospitalized patients with GBS, autonomic dysfunction most frequently manifests as diarrhea/constipation (15.5%), hyponatremia (14.9%), syndrome of inappropriate antidiuretic hormone secretion (SIADH, 4.8%), bradycardia (4.7%), and urinary retention (3.9%). The study included 2587 patients with GBS and 10,348 controls. [96]

Dysautonomia is more frequent in patients with severe weakness and respiratory failure. Autonomic changes rarely persist in a patient with GBS.
