Elderly Loss of Taste: Natural Aging Effect or Underlying Disease?
The loss of taste, known as ageusia, is not a common, inevitable consequence of aging in older adults. While it is true that the natural aging process affects the number and function of taste buds, reducing sensitivity to flavors, complete loss of taste is usually a sign of an underlying health issue.
Ageusia can lead to a range of problems, including weight loss due to inadequate nutrient intake, psychological distress, and social withdrawal. In older adults, this condition is often linked to underlying conditions such as poor general health, polypharmacy (use of multiple medications), metabolic diseases, cancer, neurological disorders, or olfactory dysfunction.
The human adult tongue typically contains around 2,000 to 4,000 taste buds, each with 10 to 50 sensory cells. Age-related physiological decline affects these taste buds, but it usually results in taste disorders such as hypogeusia (reduced taste) rather than complete ageusia.
Oral infections, like oral thrush and gum disease, can also alter flavour and decrease sensitivity. If an infection directly impacts the taste buds or taste receptors, it may cause permanent loss of taste in immunocompromised individuals.
Certain medications, such as antidepressants, antihypertensives, and diuretics, can interfere with taste. Neurological conditions, like Parkinson's disease, can cause impaired taste and smell. Head and neck injuries, as well as Alzheimer's disease, can also impact the brain's ability to "read" sensory information, potentially leading to taste disorders.
It is important to note that certain infections, such as COVID-19, can cause temporary loss of taste. In older adults, sudden complete loss of taste should prompt a consultation with a healthcare provider.
In summary, age-related physiological decline affects taste but usually does not cause complete ageusia by itself. Ageusia in the elderly often signals an underlying problem such as systemic disease, medication effects, or neurological conditions. Recognizing and addressing the cause of ageusia is important to prevent complications like malnutrition. Therefore, ageusia in the elderly should prompt clinical evaluation rather than be considered a normal, harmless consequence of aging.

- Certain medications, like antidepressants, antihypertensives, diuretics, and CBD, can interfere with taste.
- Neurological conditions, such as Parkinson's disease, can cause impaired taste and smell.
- Head and neck injuries, Alzheimer's disease, and certain therapies and treatments can also impact the brain's ability to "read" sensory information, potentially leading to taste disorders.
- Temporary loss of taste can be caused by infections such as COVID-19.
- In older adults, sudden complete loss of taste should prompt a consultation with a healthcare provider.
- Recognizing and addressing the cause of ageusia is important to prevent complications like malnutrition, mental health issues, and other medical conditions.
- Ageusia in the elderly should prompt clinical evaluation rather than being considered a normal, harmless consequence of aging.
- The loss of taste can affect overall health and wellness, including nutrition, cardiovascular health, and eye-health, as well as fitness and exercise, skin care, sexual health, and hearing.
- In the workplace, dealing with ageusia might require workplace-wellness programs to address potential issues like weight management and mental health.
- Parenting may also be impacted if a parent is dealing with ageusia, as it might affect their ability to properly feed their children and monitor their nutritional needs.
- For certain autoimmune disorders, digestive-health issues, respiratory-conditions, skin-conditions, neurological-disorders, and cancers, ageusia might be a symptom that requires medical-intervention and medicare coverage.
