Endocrine Myopathies

Diagnosis

How are endocrine myopathies diagnosed?

Severe bouts of weakness related to a disturbance of thyroid function sometimes are confused with inherited periodic paralysis. Your doctor may order blood tests to check your thyroid function, especially if a family history of this condition is lacking.

Doctors frequently measure the level of thyroid-stimulating hormone (TSH) in a blood sample to determine whether the myopathy is endocrine-related or to rule out the endocrine myopathies.
