Anosmia
Anosmia is loss of smell; it is often linked with viruses and nasal inflammation, but may also follow trauma, polyps, medications or neurological disease.
Anosmia is complete or marked loss of smell. It may be temporary after viral infection or nasal congestion, but sometimes points to a more serious cause.
Causes include respiratory viruses and COVID-19, allergic rhinitis, sinusitis, nasal polyps, head injury, toxin exposure, some medications and neurological diseases.
Why It Matters
Smell affects taste, appetite, safety and quality of life. A person with anosmia may not notice smoke, gas, spoiled food and may enjoy food less.
Diet And Keto
Loss of smell can change food choices: people may seek more salt, acidity, spice or crunch. On keto, it is important not to drift into monotony and to maintain enough protein and energy.
What May Help
Smell training is sometimes used after viral anosmia. Treatment depends on the cause: nasal inflammation, polyps, allergy, infection or trauma consequences require different approaches.
When To See A Doctor
One-sided nasal blockage, nosebleeds, severe headaches, neurological symptoms, head trauma or smell loss without a clear cause require assessment.
How To Stay Safe
With smell loss, working smoke and gas detectors, date labels on food, caution with stoves and attention to food texture are useful. These simple measures reduce everyday risks while smell is impaired.
