Myopathies associated with thyroid disease
Abnormal thyroid function can cause a myopathy. Thyroid disorders can lead to neuromuscular manifestations, including thyrotoxic myopathy, hypothyroid myopathy, thyrotoxic periodic paralysis, and thyroid-associated ophthalmopathy. The clinical features of hypothyroid myopathy are proximal weakness, fatigue, slowed contraction and relaxation, stiffness, myalgia, and myoedema. Dyspnea may be the presenting symptom in hyperthyroid myopathy, in contrast to most other endocrine myopathies.
