Muscle wasting is also known as which of the following?

Muscle wasting, the loss of muscle mass and strength, is commonly referred to as cachexia. This condition often arises in chronic disease states, such as cancer, chronic kidney disease, or heart failure, where the body's metabolism is altered, leading to a significant loss of weight and muscle tissue, despite adequate nutrition. Cachexia can severely impact a patient's functional status and quality of life, making it crucial for healthcare professionals to recognize and address.

Other terms mentioned, such as hypertrophy, refer to muscle growth rather than wasting, while stenosis describes a narrowing of bodily passages or openings. Osteoporosis pertains to the reduction in bone density and mass, not muscles. Thus, cachexia is the correct term that accurately describes muscle wasting.
