Myasthenia gravis is a complex autoimmune disorder. It causes antibodies to destroy the connections between your muscles and nerves. This causes muscle weakness and tiredness.
Only about 20 out of 100,000 people get this disorder. In young people, myasthenia gravis happens more in women than in men. Some people just have weakness in the eye muscles. Others have weakness in the face, arms, and legs.
Myasthenia gravis may be of special concern during pregnancy. Some women with the disease have breathing problems (myasthenic crisis) while pregnant. In other women, the disease may go into remission. This is when some or all symptoms go away. Pregnancy does not seem to make the disease worse.
