Among the many lingering effects of COVID-19, few are as disorienting as loss of smell — a condition clinically known as anosmia. For many residents dealing with loss of smell COVID Kalaburagi, the symptom first appeared during the acute infection and never fully resolved, sometimes stretching weeks or months beyond recovery. Whether your sense of smell disappeared suddenly at the onset of COVID or faded gradually in the weeks that followed, an ENT evaluation can provide both answers and a clear path forward. At Dr. Patil's ENT Hospital, Kalaburagi, we have been diagnosing and treating nasal and olfactory disorders for over six decades, and post-COVID anosmia has become one of the most frequently discussed concerns in our clinics.

Why Does COVID-19 Cause Loss of Smell?

Unlike a cold or flu, where nasal congestion physically blocks odour molecules from reaching smell receptors, COVID-19 causes anosmia through a different mechanism. The SARS-CoV-2 virus primarily attacks the sustentacular (supporting) cells of the olfactory epithelium — the thin tissue lining the roof of the nasal cavity that houses the smell receptors. When these supporting cells are damaged or destroyed by the viral infection, the olfactory neurons lose structural support and stop functioning properly, even when the nasal airway itself remains clear.

In some cases, the virus can also directly affect the olfactory bulb, the region of the brain that first processes smell signals. This neurological involvement explains why post-COVID anosmia can be so persistent: the nerve pathways involved in smell are among the slowest in the human body to regenerate.

Some patients also report parosmia (distorted smell, where familiar odours become unpleasant or unrecognisable) and phantosmia (phantom smells with no external source). Both are signs of impaired olfactory nerve regeneration and warrant a proper ENT assessment rather than a wait-and-see approach.

How Long Does Post-COVID Anosmia Last?

Recovery timelines vary considerably from patient to patient. Research and clinical observation suggest the following general patterns:

  • Short-term recovery (within 4 weeks): The majority of patients who lose smell during acute COVID infection regain it within one month of falling ill.
  • Medium-term recovery (1–6 months): A significant minority continue to experience reduced or absent smell for one to six months. Gradual improvement is common during this window, often starting with the return of strong odours before subtler scents recover.
  • Long-term or persistent anosmia (beyond 6 months): A smaller group of patients — sometimes referred to as having long-COVID olfactory dysfunction — may experience symptoms lasting beyond six months. Without targeted intervention, full recovery in this group is less predictable.

If you are past the six-week mark with no meaningful improvement, this is a clear signal to seek a formal post-COVID ENT evaluation rather than waiting further.

What an ENT Evaluation Involves

Many patients assume that little can be done for post-COVID anosmia, which is why they delay seeking care. In reality, a structured ENT assessment can identify treatable contributing factors and open the door to effective rehabilitation strategies. At Dr. Patil's ENT Hospital, Kalaburagi, a post-COVID olfactory evaluation typically includes:

Detailed Symptom History

The specialist will explore when the loss occurred, whether it was sudden or gradual, whether any partial recovery has taken place, and whether parosmia or phantosmia are present. This history helps differentiate between pure olfactory nerve damage and secondary causes such as ongoing nasal inflammation.

Nasal Endoscopy

A nasal endoscopy allows the ENT surgeon to directly visualise the nasal cavity and identify any structural issues — such as nasal polyps, persistent mucosal swelling, or chronic sinusitis — that may be blocking odour molecules from reaching the olfactory cleft, compounding the nerve-related deficit.

Olfactory Testing

Standardised smell identification tests help objectively grade the degree of olfactory loss — distinguishing between hyposmia (partial loss) and complete anosmia — and serve as a baseline against which treatment response can be measured over time.

Treatment Options for Post-COVID Smell Loss

There is no single cure for post-COVID anosmia, but several evidence-based interventions can accelerate recovery and improve outcomes:

Olfactory Training (Smell Training)

Olfactory training is currently the most well-supported rehabilitation strategy for post-viral smell loss. It involves deliberately and repeatedly sniffing four distinct scents — typically rose, eucalyptus, lemon, and clove — twice daily for a minimum of twelve weeks. The repeated olfactory stimulation is believed to promote neuroplasticity, encouraging the olfactory neurons to rebuild functional pathways. Patients who are consistent with smell training report measurably better outcomes than those who rely on time alone.

Intranasal Corticosteroid Sprays

Where post-COVID nasal inflammation is identified as a contributing factor, intranasal corticosteroid sprays can reduce mucosal swelling and improve airflow to the olfactory cleft, making it easier for odour molecules to reach surviving smell receptors. These are prescription medications and should only be used under ENT guidance to ensure correct technique and appropriate duration.

Oral Corticosteroids (Selected Cases)

In some cases of persistent, severe anosmia, a short supervised course of oral corticosteroids may be considered to reduce neuro-inflammation. This is not appropriate for all patients, and the decision must be made carefully by a specialist after weighing individual risk factors — another reason to seek a formal ENT review rather than self-medicating.

Vitamin and Nutritional Support

Emerging evidence supports the role of omega-3 fatty acids and Vitamin A supplementation in supporting olfactory nerve regeneration, though these should be used as adjuncts to structured training rather than standalone treatments. Your ENT specialist can advise on whether supplementation is appropriate for your situation.

When Should You See an ENT in Kalaburagi?

Not every case of post-COVID smell loss requires urgent specialist review, but you should not delay if any of the following apply:

  • Your smell has not returned at all after six weeks or more following COVID recovery.
  • You are experiencing parosmia — previously pleasant smells (food, coffee, soap) now smell foul or chemical-like.
  • You had a pre-existing nasal condition such as chronic sinusitis, nasal polyps, or a deviated septum that may now be worsening.
  • The loss of smell is affecting your appetite, nutrition, or mental wellbeing significantly.
  • You also notice persistent nasal blockage, post-nasal drip, or facial pressure that suggests an ongoing sinus issue beyond the initial COVID infection.

Early evaluation is always better than prolonged waiting. The olfactory system has a limited window during which active intervention is most effective — intervening at three months yields better results than waiting until twelve months have passed.

Living With Smell Loss: Practical Advice

While you pursue treatment, a few practical measures can help you stay safe and maintain quality of life:

  • Install smoke detectors and gas leak alarms in your home, as you may not detect fire or gas odours early enough.
  • Check expiry dates carefully on perishable food rather than relying on smell to detect spoilage.
  • Keep a smell training journal to track subtle changes over time — improvement in anosmia is often gradual and easy to miss without a record.
  • Discuss any mood changes or anxiety related to your smell loss with your doctor; anosmia has documented links to depression and reduced quality of life.

At Dr. Patil's ENT Hospital, Kalaburagi — serving patients across the Hyderabad-Karnataka region since 1963 — our specialists are well-versed in the full spectrum of post-COVID nasal and olfactory concerns. If you or a family member is struggling with persistent smell loss after COVID, do not dismiss it as something that will simply resolve on its own. A thorough evaluation can make a real difference to how quickly and completely your sense of smell returns.
