What should you know about loss of smell after covid?

COVID-19 may affect smell sensing and the way the brain interprets odours. Some people notice reduced smell, no smell, or distorted smells as they recover. Taste can seem weaker because flavour depends heavily on smell. Nasal blockage from Common Cold, Allergic Rhinitis, or Chronic Sinusitis can add another explanation.

Ongoing symptoms after the infection may fit Long COVID, but a lasting change should not automatically be attributed to it. A clinician can examine the nose, review timing, and consider other causes when recovery is incomplete or the symptom changes.

Avoid relying on smell to detect smoke, gas, spoiled food, or chemical fumes. Check alarms and use dates and safe storage practices. Saline rinsing may be suitable for some nasal symptoms, but use only properly prepared or sterile water and follow product directions.

Keep a simple record of whether smells are absent, reduced, or distorted. Smell training with familiar, distinct scents may be discussed with a clinician. Avoid inserting irritants into the nose, and seek advice before using medicated sprays for a prolonged period.

Arrange a review if smell has not returned as expected, is worsening, or interferes with eating and safety. Seek urgent care for a severe sudden headache, weakness, confusion, seizure, head injury, or breathing difficulty.

Could nasal inflammation or another condition be contributing? Is smell training suitable for me? How should I manage food and household safety while smell is reduced?
