What is cachaxia?

Cachexia is a complex metabolic syndrome characterized by severe weight loss, muscle wasting, and decreased appetite, often seen in patients with chronic illnesses such as cancer, heart failure, and HIV/AIDS. It is not simply a result of malnutrition but involves inflammatory processes, hormonal changes, and altered metabolism. Cachexia can significantly impact a patient's quality of life and is associated with increased morbidity and mortality. Effective management requires a multidisciplinary approach, including nutritional support and treatment of the underlying condition.
