What You Need to Know About Glucocorticoid-Induced Myopathy
The Big Picture
Glucocorticoid-induced myopathy is a muscle condition caused by certain medications. Understanding its symptoms and risk factors is essential for effective management.
Contents
Symptoms to Watch For
Glucocorticoid myopathy typically presents with gradual weakness in muscles close to the body's core, such as the thighs and shoulders. This weakness can make it difficult to perform everyday tasks like climbing stairs or lifting objects. Unlike other muscle disorders, this condition does not cause muscle pain or tenderness.
Who Is at Risk?
The condition is more likely in individuals taking high doses of glucocorticoids, especially for prolonged periods. Older adults and those with physical inactivity, cancer, or respiratory conditions are at higher risk. The type of glucocorticoid preparation used can also influence risk levels.
Diagnosis and Testing
Diagnosing glucocorticoid-induced myopathy relies on patient history and the exclusion of other causes. Muscle enzyme levels are usually normal, and electromyography can show a specific pattern of muscle activity. Improvement in muscle strength after reducing glucocorticoid dosage supports the diagnosis.
