What condition describes a reduction in muscle strength and mass?

The condition that describes a reduction in muscle strength and mass is known as dystrophy. This term is often associated with a group of disorders characterized by progressive degeneration and weakness of the skeletal muscles. The most commonly recognized form of dystrophy is muscular dystrophy, which involves genetic mutations that interfere with the production of proteins essential for muscle health. As a result, individuals with this condition experience a gradual loss of muscle mass and strength, leading to increasing difficulties with movement.

The other terms do not relate to muscle strength or mass reduction. Dysuria refers to painful or difficult urination, dysmorphia typically involves a distortion of body image, and dysphagia is associated with difficulty swallowing. Hence, dystrophy is the most accurate descriptor for the condition involving muscle strength and mass reduction.
