MG is often associated with which comorbidity?

• A. Thyroid and thymus abnormalities
• B. Hypertension
• C. Glaucoma
• D. Cochlear deafness

Answer: (A)

Myasthenia gravis is an autoimmune condition where antibodies disrupt communication at the neuromuscular junction, and it commonly occurs with thymic abnormalities and other autoimmune diseases. The thymus plays a key role in developing immune tolerance, and many MG patients have thymic hyperplasia or a thymoma, making thymus abnormalities a frequent comorbidity. Autoimmune thyroid diseases, such as Graves' disease or Hashimoto's thyroiditis, also commonly accompany MG due to a shared autoimmune predisposition. That combination best reflects the typical comorbidity pattern. Hypertension, glaucoma, and cochlear deafness are not characteristic comorbidities of MG, though they can occur independently.
