myasthenia gravis-related symptoms
The first symptoms of myasthenia gravis may be: 1  Weakness of the eye muscles. 2  Difficulty in swallowing. 3  Slurred speech.
The symptoms vary enormously between people with myasthenia gravis: 1  The muscles around the eyes are most commonly affected first, as these are constantly used and can quickly tire. This causes drooping of the eyelid (ptosis), and double vision. 2  Muscles around the face and throat are also often affected.
