Myasthenia gravis is a chronic neuromuscular disease that causes weakness in the skeletal muscles. The autoimmune condition occurs when the body interrupts normal communication between the nerve cells and muscles. Without proper transmission of nerve impulses, the muscles weaken over time. Some of the most common symptoms of myasthenia gravis include difficulty swallowing, facial paralysis, difficulty talking, hoarseness, fatigue, and drooping eyelids.
