Parageusia is a disorder of taste in which foods taste wrong: metallic, bitter, rancid, or simply “off.” Causes include upper respiratory infections, COVID-19 being a notorious recent example, medications such as metronidazole and some antihypertensives, zinc deficiency, head injury, dental problems, and chemotherapy. The distortion can devastate appetite and nutritional intake, since eating becomes unpleasant and patients avoid whole food groups, risking weight loss and deficiency. Management addresses the underlying cause where possible, ensures zinc status is adequate, and uses practical strategies: emphasising foods that still taste acceptable, using plastic rather than metal cutlery for metallic tastes, and maintaining protein and energy intake through tolerated textures and temperatures. Most cases resolve as the underlying condition improves, though some persist.
