Myasthenia gravis (MG)

MG is a rare autoimmune disease that disrupts communication between your nerves and muscles. This disruption causes muscles to not always work as they should. As a result, people with MG suffer from chronic, fluctuating muscle weakness that can impact their ability to perform activities of daily living.

MG usually affects eye muscles first (called ocular MG), causing vision problems. But symptoms can progress to other parts of your body, affecting your speech, eating, mobility, and breathing. This symptom progression is referred to as generalized myasthenia gravis (gMG).

MG is a chronic disease, so it's important to work with your doctor early in your diagnosis to find a treatment plan that can help you manage it over time.
