OBSOLETE: Endocrine myopathy

Endocrine myopathy is a term that was previously used to describe muscle weakness and muscle disease (myopathy) caused by disorders of the endocrine (hormone) system. This is now considered an obsolete or outdated classification in medical databases, meaning it has been replaced by more specific diagnoses. The basic idea behind endocrine myopathy is that when certain hormone-producing glands — such as the thyroid, parathyroid, adrenal glands, or pituitary gland — do not work properly, the resulting hormone imbalances can damage or weaken muscles throughout the body. Patients with endocrine myopathy typically experience progressive muscle weakness, especially in the muscles closest to the trunk of the body (proximal muscles), such as the hips, thighs, and shoulders. They may have difficulty climbing stairs, rising from a chair, or lifting their arms overhead. Other symptoms depend on which specific endocrine disorder is causing the muscle problems. For example, thyroid-related myopathy may also cause fatigue, weight changes, and sensitivity to temperature. Because this term is now obsolete, patients who were previously diagnosed with endocrine myopathy are now more accurately classified under the specific underlying endocrine condition causing their muscle disease, such as hypothyroid myopathy, hyperthyroid myopathy, steroid myopathy, or myopathy related to Cushing syndrome or hyperparathyroidism. Treatment focuses on correcting the underlying hormonal imbalance, which often leads to significant improvement or resolution of muscle symptoms.
