Impact of laparoscopic gastric bypass in a patient with myasthenia gravis and obesity.

We present the case of a 52-year-old woman with grade III obesity, type II diabetes, sleep apnea, and severe myasthenia gravis. Due to prolonged corticosteroid treatment, she had gained weight and experienced difficulty moving. To improve her condition, a laparoscopic gastric bypass was performed with good results. Myasthenia gravis is a rare autoimmune neuromuscular disease that primarily affects women. Although it is uncommon for it to be associated with obesity, weight loss has been shown to improve the symptoms of this condition, owing to the resolution of metabolic syndrome and the optimization of acetylcholine receptors after weight loss.
