Anosmia can be upsetting, although it is often overlooked. If you have anosmia, you may realise that you can't smell items that you used to be able to smell. Others, for example, may comment on a terrible odour or a pleasant aroma that you do not sense. Many persons who suffer from anosmia have a decreased appetite and a decreased appreciation of food. This could be the first indication that something is amiss. You may experience more than one of these issues. For example, if you have anosmia and phantosmia, you will be unable to detect odours around you, but you may perceive a scent that is not present.
Anosmia is usually caused by nasal congestion, which prevents odour detection. If the traffic situation improves, this is frequently reversible. It is also fairly typical for people to lose their sense of smell as they become older. The olfactory nerve, commonly known as cranial nerve, controls the sense of smell. Anosmia can arise if this nerve is damaged or if the parts of the brain that detect your odour sense are damaged.
