Altered Taste – Causes, Diagnosis and Treatment at Emirates Hospitals Group

Altered taste, also known as dysgeusia, refers to a distortion or change in the sense of taste. It can manifest as a persistent bitter, metallic, salty, or rancid taste, or a complete loss of taste (ageusia), though the latter is less common. This alteration can significantly impact enjoyment of food and may even lead to decreased appetite or nutritional deficiencies. Changes in taste can be unsettling and affect an individual’s overall quality of life. It is important to seek medical advice if you experience persistent or concerning alterations in your sense of taste.

Causes

Several factors can contribute to altered taste:

  • Medications: Certain medications, including some antibiotics, antidepressants, and blood pressure medications, can alter taste perception.
  • Nutritional deficiencies: Deficiencies in zinc or vitamin B12 can sometimes lead to taste changes.
  • Medical conditions: Conditions like dry mouth, nerve damage, infections (sinus infections, ear infections), or neurological disorders can affect taste.
  • Radiation therapy: Radiation treatment for head or neck cancers can damage taste buds.
  • Chemotherapy: Chemotherapy drugs can also affect taste perception, often causing a metallic or bitter taste.
  • Pregnancy: Hormonal changes during pregnancy can sometimes cause temporary alterations in taste.
  • Smoking: Smoking can impair taste function.

Diagnosis

Diagnosing the cause of altered taste involves:

  • Medical history: A doctor will inquire about the nature of the taste change, any other symptoms, medications being taken, and medical history.
  • Physical exam: The doctor will examine the mouth, tongue, and throat for any abnormalities.
  • Taste testing: Formal taste testing may be performed to assess the specific taste alterations.
  • Blood tests: Blood tests can check for nutritional deficiencies or underlying medical conditions.
  • Neurological exam: If neurological issues are suspected, a neurological exam may be performed.

Treatment

Treatment for altered taste depends on the underlying cause:

  • Addressing underlying conditions: Treating any underlying medical conditions, such as infections or nutritional deficiencies, can resolve the taste problem.
  • Medication adjustments: If medication is suspected to be the cause, the doctor may adjust the dosage or switch to a different medication.
  • Oral hygiene: Maintaining good oral hygiene, including regular brushing and flossing, can help improve taste perception.
  • Saliva substitutes: For dry mouth, saliva substitutes or medications to stimulate saliva production may be recommended.
  • Nutritional supplements: If nutritional deficiencies are identified, supplements may be prescribed.

If you experience a persistent or bothersome change in your sense of taste, it is important to consult a doctor to determine the underlying cause and receive appropriate treatment.
