Which symptom is NOT associated with myasthenia gravis?

Myasthenia gravis is characterized by weakness and rapid fatigue of voluntary muscles, which can lead to symptoms such as ptosis (drooping eyelids), diplopia (double vision), and extreme fatigue, especially after prolonged activity. These symptoms result from an autoimmune response that disrupts the communication between nerves and muscles.

Muscle hypertrophy, which refers to an increase in muscle size, is not associated with myasthenia gravis. In fact, due to the nature of the disease, there is often muscle atrophy rather than hypertrophy because the muscles become weaker and less used over time. Therefore, recognizing that muscle hypertrophy does not occur in myasthenia gravis helps clarify the distinguishing characteristics of this condition compared to others that might present with different muscle responses.
