ENT doctor explains the reasons behind loss of smell

There are several factors that cause loss of smell which is also known as anosmia. The top ENT doctor from a diagnostic centre in Mukundapur provides an understanding of these factors.

Causes

Here is a breakdown of the possible causes:

• Nasal congestion

When there is a congestion in the nasal passages due to factors such as allergies, cold, nasal polyps or sinus infection, the flow of air is blocked that prevents the odour molecules from reaching the nasal smell receptors.

• Upper respiratory infections

Temporary anosmia is also caused by viral infections like cold or flu. This leads to inflammation and swelling in the nasal passages that affects the sense of smell.

• Trauma

Accidents or falls are the primary causes of injury. In case of any injury caused to the face or head that involves the nose can result in loss of smell. 

• Nasal polyps

Nasal polyps refer to non-cancerous growths in the nasal cavity. Such growths that occur in the nasal cavity create an obstruction in the flow of air and leads to an interference with the sense of smell. Moreover, they are usually associated with chronic inflammation in the nasal passages. The best way to keep your health in check is by seeking medical assistance from the best doctors of the top diagnostic centre in Mukundapur.

• Chronic sinusitis

Recurring inflammation of sinuses results in thickening in the sinus lining and blockage of the passages in the nose. Thisleads to problems-related to sense of smell.

 

• Exposure to chemicals

Another cause of anosmia is when the olfactory nerve or the nasal mucosa is damaged. The reason behind this can be the exposure to chemicals like toxic fumes, pesticides, etc.

• Neurological conditions

Neurological disorders like Parkinson’s disease, Alzheimer’s disease, tumours in the brain and Multiple Sclerosis have an effect on the nerves and regions of the brain that are linked to processing smell. 

Conclusion

It is vital to get thoroughly evaluated by a specialized doctor from the top diagnostic centre in Mukundapur to conclude the cause of anosmia and receive a treatment plan. Treatments help relieve nasal infections and they tend to focus on symptom relief.
