Various neurological disorders have been reported following bariatric surgery-induced weight loss. Here, we report 3 patients who developed multiple sclerosis (MS), one of whom also developed myasthenia gravis (MG), shortly after significant weight loss. Two patients lost weight by following a diet plan and one underwent bariatric surgery. There may be an association between significant weight loss and the development of an autoimmune neurological disorder such as MS or MG; a high index of suspicion is required.
