How long does sense of smell return after covid?

Smell may return unevenly: familiar odours can seem weak, distorted, or unpleasant before they become normal. Taste may also feel reduced because smell contributes to flavour. Ongoing loss can occur as part of Long COVID, although nasal congestion, allergies, medication effects, and other conditions can also affect smell.

The pace of recovery cannot be predicted from the first few days alone. Notice whether you can detect basic smells and whether function is slowly changing. Do not use a lack of smell to judge whether an infection is active or whether you are contagious.

Take care around smoke, gas, spoiled food, and household chemicals because reduced smell can remove warning signals. Ask a clinician or pharmacist about safe nasal care if congestion is present, and avoid inserting irritants into the nose.

Smell training may be discussed for persistent loss; it involves repeated, careful exposure to selected familiar scents over time. A healthcare professional can check whether it suits you and whether another cause needs treatment. Record changes without forcing strong or unsafe odours.

Arrange a medical review if smell loss is persistent, worsening, one-sided, associated with repeated nosebleeds, or accompanied by severe headache, neurological changes, or breathing difficulty. Seek urgent help for sudden neurological symptoms or severe breathing problems.

Could congestion, allergy, medicine, or another nasal problem be contributing? Is smell training appropriate? Should my taste change be assessed separately? What symptoms would make this urgent?
