Myasthenia gravis: Causes, symptoms, prevention, and more

Myasthenia gravis (MG) leads to weakness and fatigue in muscles, which do not remain under voluntary control. A breakdown in normal communication between nerves and muscles can lead to what is also called MG.

MG is common among women who are younger than 40 and men who are older than 60. Common symptoms include muscle weakness, drooping of the eyelids, double vision or diplopia, impaired speaking, problems in swallowing and chewing, and changes in facial expressions.

According to experts, children are sometimes born with a rare form of myasthenia gravis, called congenital myasthenic syndrome.

The illness can lead to severe complications like a myasthenic crisis, thymus gland tumors, underactive or overactive thyroid, and autoimmune conditions. A permanent cure for myasthenia gravis is not yet available.
