Loss of taste is called ageusia. Dysgeusia, while related, means a distorted or altered taste sensation—often an unpleasant or metallic taste—rather than a complete loss. The other terms refer to different issues: odynophagia is painful swallowing, xerostomia is dry mouth, and anorexia is loss of appetite. In cancer care, taste changes can affect nutrition, so understanding these distinctions helps guide appropriate supportive strategies like flavor enhancement, saliva substitutes, and good oral care.
