A symptom-picture resulting from a short-term disordered liver, with constipation, frontal headache, spots in front of the eyes, poor appetite, and nausea or vomiting. The usual causes are heavy alcohol consumption, poor ventilation when working with solvents, heavy bingeing with fatty foods, or moderate consumption of rancid fats. The term is genially archaic in medicine; people who are bilious are seldom genial, however.
