How is cachexia defined?

Cachexia is a metabolic syndrome seen in chronic disease, marked by involuntary weight loss with loss of skeletal muscle mass and often fat tissue, driven by abnormal metabolism and inflammatory signals. It goes beyond simply not eating enough; even with adequate nutrition, catabolic processes continue to erode tissue. The description that emphasizes a general lack of nutrition with wasting of both muscle and adipose tissue during chronic illness, usually due to metabolic abnormalities, best fits this concept. Localized fat loss or normal nutrition with illness do not capture the systemic, catabolic nature of cachexia.
