Summary
- Myasthenia gravis is an autoimmune disease that causes muscle weakness.
- The symptoms are caused by the immune system interfering with the transmission of messages from the nervous system to the muscles.
- There is no cure, but the symptoms can be managed.

- Fatigue, insufficient sleep
- Stress, anxiety
- Illness
- Overexertion, repetitive motion
