17. Cachexia
Patients with advanced prostate cancer can also suffer a syndrome known as cancer-related cachexia. It is a wasting syndrome that includes weight loss, loss of appetite, muscle weakness, and fatigue. All of these symptoms are related to each other, and the cause is deeply rooted in metabolic abnormalities caused by cancer cells. What basically happens is that cancer takes up significant energy from the body to keep growing. It robs energy that other organs should have used instead. The inflammatory state also causes loss of appetite, and there is a reduction in the number and quality of nutrients the patient is receiving. Patients lose weight and start feeling fatigued and tired.
