Anorexia is the involuntary loss of appetite that has been reported to be as high as 80% in patients with various types of late-stage cancers. Anorexia is the most prominent symptom in the anorexia–cachexia syndrome that has been described in patients with cancer. ONS PEP resources address anorexia as a unique symptom separate from the entire cachexia syndrome. Many factors contribute to the loss of appetite associated with cancer or other disease processes as well as oncologic treatment side effects.
