Introduction: Pregnancy-related Guillain-Barré syndrome (GBS) is a rare autoimmune disorder that affects pregnant women. With an annual incidence ranging from 0.81 to 1.89 cases per 100,000 population, GBS can occur at any trimester of pregnancy, as well as during the postpartum period are susceptible to GBS. The pillars of managing pregnancy-related GBS to improve outcomes include early diagnosis, prompt immune-modulatory therapy, and multidisciplinary input. Case Series: In this study, three case of GBS in pregnancy were reported. The first patient was a 35-year-old woman, G3A1P2 post emergency Transperitoneal Cesarean Section (TPCS), who experienced with lower limb weakness three days before TPCS. After being diagnosed with severe eclampsia and underwent emergency TPCS, her complaint of lower limb weakness worsened. The second patient, a 27-year-old woman, with G2P1A0 experienced weakness in all four limbs. The third patient, a 20-year-old woman with G1P0A0, in the third semester presented with weakness in all four limbs. The electroneurography investigation conducted on these patients supported the diagnosis of GBS, which was subsequently managed with plasma exchange (PE). After the administration of PE, there was observed improvement in the clinical manifestation of GBS. Conclusion: The development of GBS in pregnancy is typically preceded by bacterial or viral infection. Preeclampsia was found to be associated with two folds risk of GBS, which was usually diagnosed based on the neurological examinations with supportive studies, including serological tests, cerebrospinal fluid analysis and electroneurography. The management of pregnancy-related GBS included intravenous immunoglobulin, PE, physiotherapy, and supportive therapy, such as ventilator support.
