Hello Welcome in H.C.M. Regarding your query for change in taste of any thing you take, I would like tell you that taste is always percieve by taste buds which are present mainly over tongue but flavour is appreciated by our nose. So truely speaking taste and flavour both combindly give us delisus feeling. Therefore any disease of mouth involvig tongue and olfactory area of nose may creat loss of taste like- 1- Severe dyspepsia. 2- Gossitis. 3- Severe cold. 4- Huge nasal polyps. 5- High grade fever. all above may be diagnosed clinically and manage accordingly. Regards.
