Guillain–Barré syndrome (GBS) is an autoimmune disease. Estimated population incidence ranges from 0.62 to 2.66 cases per 100,000 person-years across all age groups. We report a case of GBS in a 22-year-old primigravida who presented at 36 weeks of the period of gestation (POG), with complaints of bilateral progressive lower limb numbness and weakness for 2 weeks duration. Magnetic resonance imaging of the brain was done to exclude other possible causes. Diagnosis of GBS was made according to the Brighton criteria, which our patient falls into Level 2. She received intensive care management. The patient improved rapidly without any specific management. She went to labor spontaneously and delivered a healthy baby with a birth weight of 2.8 kg at 38 weeks of POG. She continued to receive supportive therapy and improved significantly.
