Question

how do we perceive smell why do we loose sense of taste and smell when we have cold​

Answer 1

Answer:

Explanation:

Smell disorders can present different symptoms, including:

Hyposmia – a lessened ability to detect odors

Anosmia – a complete inability to detect odors

Parosmia – a change in the normal perception of scents (e.g., what used to smell pleasant is now foul)

Phantosmia – the perception of an odor that is not present

1. Viral infections like the flu, colds and COVID-19

2. An early sign of neurological conditions

Smell and taste are processed through the brain, so it might not be surprising that conditions affecting the brain, like Parkinson’s disease or Alzheimer’s disease, are linked to disruptions or a loss of these senses, especially smell.

3. Nasal polyps

If you’re prone to frequent sinus infections, you may develop nasal polyps, benign growths in the nose.

“Nasal polyps and chronic sinus disease affect smell because they lead to inflammation of the lining of the nose, which prevents odor molecules from reaching the smell nerves,” Ference says.

4. Age

According to the National Institutes of Health, up to one in four Americans over the age of 40 may experience changes in their sense of smell; that number increases to nearly one in three for people over the age of 80. When it comes to taste, one in five Americans may experience changes after they turn 40.

As we age, several factors can contribute to a loss of taste and smell, including dental issues, dry mouth, certain medications, alcohol consumption and smoking. In addition, less mucus production in the nose, a loss of nerve endings and changes in the taste buds can occur as we age, affecting smell and taste.

If you’re experiencing a loss of taste and smell, talking to your primary care physician or visiting an otolaryngologist, a doctor who specializes in the conditions of the ear, nose and throat, may help you pinpoint what’s causing these changes in your senses.
