A diminished sense of smell puts seniors at high risk for food poisoning, gas inhalation, and fire hazards. Caregivers must be vigilant, checking the refrigerator for spoiled food, ensuring smoke detectors are functional, and installing explosive gas alarms to protect loved ones who can no longer smell danger.
When we think of sensory decline, vision and hearing take center stage. However, the loss of the sense of smell (anosmia or hyposmia) is incredibly common in older adults and presents severe, often overlooked safety hazards. Olfactory decline can be a natural part of aging, but it can also be an early warning sign of neurological conditions like Parkinson's or Alzheimer's disease. Regardless of the cause, caregivers must treat a fading sense of smell as a critical safety issue.
The Risks You Can't See
Our sense of smell acts as a primal warning system. Without it, seniors are stripped of their ability to detect imminent danger. The most immediate risk is food poisoning. If a senior cannot smell the sourness of expired milk or the putrid scent of rotting meat, they are highly likely to consume spoiled food, leading to severe gastrointestinal illness.
Even more terrifying are environmental hazards. A senior with olfactory decline cannot smell the distinct "rotten egg" odor added to natural gas, meaning a stove left on without a flame could lead to a lethal gas leak or explosion. Similarly, they may not smell the acrid scent of smoke from a smoldering electrical wire or a forgotten pan on the stove until a fire is already raging.
What Caregivers Must Do
You cannot restore a lost sense of smell, but you can implement safety protocols. As a caregiver, you must become the "designated smeller." Make it a habit to clean out their refrigerator weekly, strictly adhering to expiration dates and throwing away any leftovers older than three days. Most importantly, upgrade their home safety technology. Ensure there are loud, interconnected smoke detectors in every room, and install explosive gas and carbon monoxide detectors near the kitchen and bedrooms.
