Chronic alcoholic myopathy (Q93213)

Chronic alcoholic myopathy is a common complication of alcoholism affecting approximately 50% of patients. It primarily affects the white muscle fibres of the pectoral and pelvic girdles, though other muscle groups may be involved. Approximately 50% of affected patients show proximal muscle weakness. It is not associated with nutritional, vitamin or mineral deficiencies. The atrophy of the muscle fibres does not lead to an increase in serum creatine kinase and is reversible with 6-12 months abstinence.
