What is the true cost of living without your sense of smell?

A new study uncovers the emotional and physical impact on life when someone experiences a long-term or permanent loss of smell.  From personal hygiene to memory recall, read on to learn more about the study findings.

More Than A Smell
Share Article

Most of us have experienced a temporary loss of smell with a cold or sinus allergies.  It’s a foreign and uncomfortable sensation, but for the most part- short-lived. All we are left with is the realization of how our sense of smell is taken for granted.  But for some, anosmia (loss of smell) can last for longer periods of time, or even permanently. A new study sheds light on the severe impact anosmia can have on our overall well-being.

The Problem

Anosmia is the temporary, or permanent, loss of your sense of smell. It affects millions of Americans each year and up to 20% of the population. According to the National Institute on Deaf and Other Communication Disorders, almost 1 to 4 persons in the U.S. experience a change in their ability to smell.  Since your sense of smell is directly related to your ability to taste, anosmia commonly leads to a loss in your sense of taste as well.

What Is Known

Through previous research, we know a loss in sense of taste can lead to a decreased appetite and high rates of depression, anxiety and isolation.  Researchers at the University of East Anglia’s Norwich Medical Center wanted to learn more about the life-altering impacts losing your ability to smell has on overall physical and emotional health.

Study Details

Researchers conducted a qualitative study, with 71 participants aged 31-80,  who were seeking support from a clinic specializing in smell and taste disorders.  The team analyzed participants' written personal accounts of what it was like living with a smell disorder.  The study shows people with smell disorders can experience a wide range of issues that disrupt everyday life.  

Common Themes Emerge

Researchers identified several common themes when studying the lived experience described by each participant.  Let’s take a closer look at the findings.

Impact on Safety

Some participants reported a serious injury “near miss” from not being able to pick up on warning smells.  Study researcher, Professor Carl Philpot, explains “one really big problem was around hazard perception- not being able to smell food that had gone off, or not being able to smell gas or smoke”.

Quote

"But smell is not just a life-saving sense - it is also life-enhancing.”

-Professor Carl Philpot

Impact on Nutrition

Loss of appetite and weight loss was another theme identified by researchers.  Some participants experienced weight gain from eating less nutritious foods that were high in fat, salt and sugar. The impact of anosmia also extended beyond nutrition. Participants reported both social and emotional ramifications, such as

  • No longer enjoyed eating
  • Lost interest in preparing food
  • Embarrassed to serve food to  family and friends

Impact on Memory Recall

Certain smells are often linked to happy memories. Memories may often be associated with people, places or emotional experiences.  Without the ability to smell, participants reported missing the memory link connection. Examples include:

  • An aroma that reminds you of a favorite holiday
  • The scent of a baby
  • Smelling perfume worn by a loved one who has passed
  • A scent that brings emotional comfort, such as lavender

Impact on Relationships

Many participants felt relationships were negatively impacted, including sexual relationships.  Negative emotions were described as a result of lost socialization or intimacy. Reported emotions include:

  • Anxiety
  • Depression
  • Anger 
  • Frustration
  • Low confidence
  • Isolation
  • Regret 
  • Sadness

Hygiene Concerns

Imagine not being able to smell yourself to pick up on cues of a hygiene issue?  This was a source of anxiety and embarrassment for study participants. One mother described feeling like a failure because she couldn’t tell when her baby’s diaper needed to be changed.

What Causes Anosmia?

There are many reasons why someone experiences a loss of smell, ranging from physical conditions to certain medications. A common cause is irritation of your nose lining or blockage of nasal passages. Your ability to smell can also be altered due to neurological conditions, including certain medical diagnoses.  For a comprehensive look at anosmia causes, visit Mayo Clinic: Loss of Smell.

What Nurses Can Do

Participants didn't feel like their healthcare team understood the impact anosmia had on their overall wellbeing. In fact, many described frustrating and unhelpful interactions with care providers.  The researchers hope the study findings will improve understanding within the medical community.

I have no sense of smell. I worked with super glue and epoxy back in the 1960s when there were no warning labels on cans. I was diagnosed with Chronic Asthmatic Bronchitis back in 2002. The doctor I had at the time didn't believe I had asthma until I was tested for it and other lung ailments. I fired him soon after that and now have a much more proficient doctor who was responsible for saving my life more than once.
