Reduced or Loss of Smell (Hyposmia)

Hyposmia, or a reduced sense of smell, is a condition where your ability to detect odors is weakened but not completely lost. This can occur for many reasons, including chronic sinusitis, nasal polyps, or allergies that block the flow of air to the smell receptors in your nose. Viral infections, such as the flu or COVID-19, are also common triggers, as they can damage the nerve pathways responsible for detecting smells. Less commonly, neurological conditions or even aging can contribute to hyposmia.

Treatment depends on the cause. For sinus-related issues, medications or minimally invasive procedures to improve airflow may help. In cases of post-viral hyposmia, recovery can take time, though some patients benefit from smell training or specific therapies. If you’re experiencing a reduced sense of smell that persists or worsens, a thorough evaluation can help pinpoint the cause and guide you toward effective solutions.
