Taste disorders

What are taste disorders?

Taste disorders are those that result in an increase, decrease, absence or change in our sense of taste. Taste and smell are two senses that can be almost impossible to separate, so often these are referred to as smell and taste disorders. Common taste disorders include:

  • Hypogeusia (loss or reduction in taste sense)
  • Dysgeusia (having an abnormal taste)

In general, taste disorders can be described as being either an increased or decreased sensitivity to sweetness, bitterness, saltiness and sourness. Sometimes, people can describe having a metallic taste in their mouth. 

Common causes of taste disorders are:

  • Smoking
  • The common cold
  • Sinus infection
  • Poor oral hygiene
  • Recreational drug use (e.g. cocaine)
  • Certain medications 
  • Other illnesses
