What causes bad smell

summary

There are many reasons for olfactory failure. Some nasal diseases may cause olfactory failure. Such as sinusitis, nasal polyps and tumors in the nasal cavity and so on. When people have a cold, they are more likely to have the phenomenon of olfactory failure. This situation does not need to worry too much. After the cold is cured, it will naturally recover. Next, I'd like to introduce to you what causes the bad sense of smell.

What causes bad smell

First: long term inflammatory stimulation will lead to olfactory dysfunction. If you want to recover your olfactory function, you must first cure your rhinitis, and then your olfactory function will gradually return to normal. Suffering from rhinitis should pay attention to proper rest, ban alcohol and tobacco, keep indoor air circulation clean.

Second: olfactory hypersensitivity, that is, slight smell but very strong, can be caused by olfactory neuritis or neurosis.

Third: nervous olfactory decline: drugs, poisons, harmful gases damage olfactory mucosa, olfactory nerve and senile olfactory degeneration.

matters needing attention

Olfactory failure, first of all, should be as early as possible to the hospital specialist examination, check whether the nasal obstruction disease. If after a period of treatment and observation, the condition is still not improved or the olfactory function is further reduced, further examination, including sinus CT, should be done to exclude other possible causes, such as sinusitis, early nasal polyps, olfactory nerve tumors, and then treatment should be carried out according to the etiology.
