What's This About?
Muscle weakness can be a symptom of various medical conditions, ranging from minor to serious. Understanding the causes and patterns of muscle weakness is crucial for proper diagnosis and treatment.

Common Patterns of Muscle Weakness
Muscle weakness often follows specific patterns that can provide clues about the underlying cause. Proximal weakness, affecting the shoulders and hips, is common in many muscle disorders. Some conditions cause more distal weakness in the hands and feet. Others may affect muscles in the eyes, face, and throat. The pattern of weakness can help doctors narrow down potential causes.
When to Worry About Muscle Weakness
While occasional muscle fatigue is normal, persistent or progressive weakness warrants medical attention. Red flags include sudden onset of weakness, asymmetric weakness, or weakness accompanied by other symptoms like pain, numbness, or vision changes. Muscle weakness affecting daily activities or quality of life should be evaluated promptly.
Diagnosing the Cause of Muscle Weakness
Diagnosing muscle weakness involves a comprehensive approach. Your doctor will take a detailed history, perform a physical exam, and may order blood tests to check muscle enzymes. Additional tests like electromyography, imaging studies, or muscle biopsy may be needed in some cases. Genetic testing can help identify inherited muscle disorders.
