Dysgeusia
From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history
(Redirected from Changes in taste)
Dysgeusia or parageusia is an altered sense of taste, which may involve a persistent unpleasant taste, ageusia is a total loss of sense of taste, and hypogeusia is a reduced ability to taste sweet, sour, bitter, salty or umami (delicious/savoury) tastes.[1][2]
A change in sense of smell may occur alongside a change in sense of taste.[1][3]
