Not Just Covid-19, This Is Another Cause of Anosmia


TEMPO.CO, JakartaAnosmia or loss of sense of smell and taste is one of the symptoms of Covid-19. Although it does not cause severe complications in the body, it can be very distressing and affect quality of life in several ways. Experts also claim impaired sense of smell can persist in the days following COVID-19 infection, which is why it is also a sign of long Covid.

However, the olfactory system can be affected by many other causes. Apart from the corona virus, the disappearance of sense of smell can be triggered by other factors as reported by Times of India following.

Nasal polyps
Nasal polyps are noncancerous growths in the nasal passages that are painless but uncomfortable. Polyps can hang into the nostrils or extend to the throat area, causing blockage of the nasal passages, causing congestion, breathing problems, headaches, and loss of smell. Nasal polyps are the result of chronic inflammation, allergies, or certain immune disorders.

Allergies, sinusitis, flu, colds
Just like COVID-19, various other respiratory viruses can cause a loss of smell. Infections such as the common cold can cause anosmia, which can persist for some time. Severe allergies and chronic sinus problems are some of the common causes of loss of smell. The loss of smell and taste with allergies is caused by nasal congestion. Given that the nasal passages are blocked for any reason, particles become difficult to reach the nerves in the nose, which are responsible for the olfactory function.

Aging
The nasal cavity has olfactory receptors that transmit information via nerves to the brain, facilitating functions such as smell. That said, conditions such as anosmia can occur if nerves are damaged. That said, loss of the sense of smell and taste can be a possible result of aging as nerves and receptors weaken over time, with age. This condition is also known as presbyosmia, which refers to the gradual degeneration of the sense of smell due to aging, which is common in those aged 70 and over.

Head injury
People may lose their sense of smell after experiencing a traumatic head or brain injury. This is because some parts of the brain are linked to the olfactory system. The orbitofrontal cortex, which is above and behind the eye, the insula, which is below the ear, and the piriform cortex, which is located between the other two parts, are concerned with the function of smell. Head injuries can cause damage to any or all of these areas, causing anosmia.

Drugs
Certain drugs and toxic chemicals can also damage the sense of smell. Antibiotics such as ampicillin and tetracycline, spray nose Decongestants, some antidepressants and antihistamines, can cause anosmia.
