Severe, progressive muscle wasting in cancer patients caused by metabolic changes beyond simple malnutrition.
A severe wasting syndrome characterized by progressive loss of body weight, muscle mass, and fat despite adequate caloric intake. It results from cancer-induced metabolic dysfunction and inflammation.
Cancer cachexia is a complex metabolic syndrome distinct from starvation—patients lose weight even when eating adequately. The cancer produces inflammatory cytokines (IL-6, TNF-alpha) that increase metabolic rate, reduce appetite, and trigger muscle protein breakdown. These systemic effects override normal nutritional compensation, making standard nutritional support alone insufficient. Cachexia significantly worsens prognosis, reduces chemotherapy tolerance, and impairs quality of life. It requires multifaceted intervention combining nutrition, exercise, pharmacotherapy, and inflammation management.
Understanding and treating cancer cachexia preserves functional capacity, improves treatment tolerance, and enhances survival and quality of life.
Combine adequate protein intake (1.2-1.5 g/kg daily) with resistance exercise, omega-3 supplementation, and anti-inflammatory foods. Work with your oncology team to address underlying inflammation and consider appetite-stimulating medications if appropriate.
Cancer cachexia requires a comprehensive, multifaceted approach combining nutrition, exercise, and medical management beyond standard dietary intervention.
