Anorexia.

In medicine, specific combinations of symptoms and signs contribute to establishing a diagnosis. However, symptoms or constellations of symptoms (i.e., syndromes) per se may not be specific for a single disease; rather, they are observed during the clinical course of a number of acute and chronic diseases. Among them, anorexia is a highly prevalent syndrome that heavily impacts on the prognosis of patients suffering from acute (i.e. sepsis) and chronic (i.e. cancer, liver cirrhosis, chronic renal failure, chronic obstructive pulmonary [COPD]) diseases.
