Myasthenia gravis (MG) is a rare, chronic, autoimmune, neuromuscular1 condition where the body’s immune system mistakenly targets the connection between the nerves and the muscles2.
In people living with MG, voluntary muscles don’t respond well to the signals sent by the brain.3 The main symptoms are extreme muscle weakness and fatigue4.
Additionally, the severity of muscle weakness worsens over time, an event called muscle ‘fatigability’4. On rare occasions the weakness can be life-threatening when people lose the ability to swallow or to breathe5. This is an MG crisis5.
The actual symptoms of MG vary greatly, so individuals experience it in a very personal way which can cause profound uncertainty1,6.
Symptoms of MG are unpredictable and can fluctuate over days or even hours.
There is currently no cure for MG13. There are a number of options available to help manage and control MG symptoms14. Whilst treatments are effective for most, they do not help all people with the condition15.
