What may help loss of smell

A cold may temporarily narrow the nasal passages, while allergic rhinitis can repeatedly trigger swelling and discharge. Chronic sinusitis may cause persistent inflammation, pressure, or thick mucus. Viral illness can affect smell signalling even after congestion improves, and COVID-19 or Long COVID may be considered when the timing fits. Other possibilities include a medicine effect, nasal growth, or a head injury. Because these causes need different approaches, a remedy that helps one person may be unsuitable for another.

Treat the underlying illness as advised, rest, and drink enough fluid. Saline spray or a properly prepared saline rinse may loosen mucus; use sterile, distilled, or previously boiled and cooled water for rinsing. A clinician may recommend treatment for allergy or sinus inflammation after examining you. Do not start antibiotics, steroid tablets, or repeated decongestant use on your own. Protect against missed warning smells by checking alarms and food with another person when needed. Keep notes on changes in smell and flavour so improvement is easier to describe.

Get urgent help for difficulty breathing, chest pain, confusion, fainting, or new neurological symptoms. Seek prompt review if smell loss follows a head injury, begins suddenly without nasal symptoms, comes with severe headache, or remains after a viral illness has resolved. A clinician can decide whether nasal examination, medicine review, testing, or specialist referral is appropriate.

Ask what cause is most consistent with your timing and other symptoms, whether saline is suitable, and which prescribed or over-the-counter medicines could affect smell. Ask how long to try a treatment, what side effects to watch for, and when persistent symptoms need ear, nose and throat review.
