Myasthenia gravis primarily manifests as an inability to swallow, affecting the pharyngeal muscles or the muscles involved in swallowing. Thus, difficulty in swallowing is also a symptom of myasthenia gravis. At this time, the main treatment should focus on the primary disease, administering medications such as neostigmine for myasthenia gravis, and using steroids or immunosuppressants in severe cases. If there is difficulty in swallowing, or if it persists for more than two or three days, a gastric tube can be inserted for nasal feeding to maintain nutrition. Then, as the symptoms of myasthenia gravis subside with medication, swallowing function can recover.
