Treatments that may help resolve anosmia caused by nasal irritation include:
- decongestants.
- antihistamines.
- steroid nasal sprays.
- antibiotics, for bacterial infections.
- reducing exposure to nasal irritants and allergens.
- cessation of smoking.
What gas will cause olfactory fatigue?
Hydrogen sulfide, as mentioned earlier, causes rapid olfactory fatigue, and the normal ‘rotten egg’ odor quickly vanishes allowing prolonged exposure to this potentially fatal mitochondrial toxin.
Which hormone is responsible for smell?
The new study shows ghrelin, made mainly in the stomach, binds to molecules in the brain’s olfactory bulb, suggesting the hormone is directly involved in odor processing.
What organ is responsible for smell?
the nose
olfactory system, the bodily structures that serve the sense of smell. The system consists of the nose and the nasal cavities, which in their upper parts support the olfactory mucous membrane for the perception of smell and in their lower parts act as respiratory passages.
What nerve controls taste and smell?
Olfactory nerve (CN I) Its receptors are located in the olfactory mucosa under the roof of the nasal cavity. The olfactory fibers cross the skull base through the olfactory foramina of the cribriform plate and enter the olfactory bulb in the olfactory groove.
What part of the brain is responsible for smell?
the olfactory bulb
Smells are handled by the olfactory bulb, the structure in the front of the brain that sends information to the other areas of the body’s central command for further processing. Odors take a direct route to the limbic system, including the amygdala and the hippocampus, the regions related to emotion and memory.

Can anosmia lead to death?
The authors speculate loss of smell does not directly cause death, but it could be an early warning sign that something has gone wrong, such as exposure to toxic environmental elements or cell damage. While this study is interesting, it does not prove that loss of sense of smell (anosmia) is a predictor of early death.
Can anosmia be cured?
There is currently no known cure for congenital anosmia. In most cases, however, anosmia goes away on its own. Generally, once the underlying problem is treated, your sense of smell is restored.
