Loss of Smell in Older Adults: Assessment and Everyday Safety

By Silver Sitters

A change in smell can affect eating and enjoyment of daily life. It should not automatically be dismissed as harmless aging. Older adults in Broward County can discuss new or persistent changes with a healthcare professional to look for a cause and appropriate support.

Different causes need different responses

Smell changes can relate to aging, respiratory or sinus infections, dental problems, head injury, medicines or other conditions. A smell problem alone does not diagnose Alzheimer’s or Parkinson’s disease. Tell the clinician when it began, whether smells are weaker or distorted, and about recent illness, injury and medicines.

Assessment may include an examination, history and smell testing. Do not stop a prescribed medicine on your own; ask the prescriber whether it could be contributing.

Watch for changes in eating

Smell contributes to flavor, so a smell problem may seem like loss of taste. Food can become less appealing and eating habits may change. Discuss reduced intake, weight changes or distress with the healthcare team. Ask about ways to make suitable meals enjoyable without simply adding more salt or sugar.

Do not rely on smell to judge food safety

Even someone with an excellent sense of smell cannot reliably detect harmful bacteria in food. Use safe storage times, temperatures and handling practices. Do not taste questionable food to test whether it is safe. A normal smell is not proof that a meal is safe to eat.

Check household warning systems

Reduced smell may make some warning odors harder to notice. Maintain working smoke alarms and a practical escape plan instead of relying on smelling smoke. Ask for help checking alarms if needed. Agree on any household support with the person, respecting their preferences and independence.
