Introspective Market Research Projects Global Anosmia Market to Hit US$ 4.47 Billion by 2032

The global Anosmia Market (loss or impairment of the sense of smell) is expected to grow from US$ 3.04 billion in 2023 to US$ 4.47 billion by 2032, at a projected compound annual growth rate (CAGR) of 4.37%. This growth is underpinned by increasing post-COVID-19 anosmia cases, greater public awareness, and ongoing advancements in diagnostic and therapeutic interventions.

Quick Insights

·         2023 market size: US$ 3.04 B

·         Projected 2032 size: US$ 4.47 B

·         Forecast CAGR (2024–2032): 4.37%

·         Top region: North America, driven by advanced healthcare infrastructure and R&D investments

·         Leading cause segment: Viral infections (especially post-COVID)

·         Severity segment dominating: Head trauma–related anosmia

·         Key players: AbbVie, AstraZeneca, Biogen, Pfizer, Novartis, Sanofi, Merck, Regeneron, and others

Growing Loss of Smell: What’s Fueling the Market

The anosmia market’s expansion is driven by several critical tailwinds. First, lingering post-COVID anosmia remains a significant clinical issue, with many patients experiencing long-term smell impairment. Second, olfactory retraining therapy a non-pharmacological intervention  is gaining acceptance as a low-risk, accessible treatment. Third, diagnostic tools are advancing: integration of artificial intelligence (AI) in smell tests and wearable olfactory sensors is enabling earlier, more nuanced detection.

Introspective Market Research’s analysis shows that viral-infection-caused anosmia (notably, post-COVID) will continue to anchor demand. At the same time, head trauma–related anosmia, often stemming from traumatic brain injuries, is forecast to hold a substantial share due to advancements in neuro-regenerative medicine and rehabilitation.

What’s Driving This Growth and What’s Holding It Back?

Key Drivers

·         Rising public awareness of anosmia and its long-term quality-of-life impact

·         Broader adoption of anosmia screening in routine clinical settings

·         Investments in regenerative therapies aimed at repairing olfactory neurons

·         Increased research funding for post-viral anosmia, especially long COVID

Challenges & Restraints

·         Limited effective therapies for irreversible anosmia

·         High cost of advanced diagnostic tools and treatment modalities

·         Need for standardized global protocols for diagnosis and management

·         Regulatory hurdles for novel regenerative or biologic treatments

Trends to Watch: What’s Next in Anosmia Care?

AI + Olfactory Diagnostics
Diagnostic platforms are increasingly leveraging AI to detect smell loss more accurately and personalize treatment. These systems can analyze patient-specific patterns and predict disease progression, helping clinicians decide whether to recommend retraining, medical therapy, or surgical intervention.

Wearable Smell Sensors
A new wave of wearable technology — such as devices equipped with olfactory sensors — allows real-time assessment of smell function outside the clinic. This emerging trend could reshape how anosmia is monitored and managed.

Post-COVID Focus
The lingering effects of COVID-19 continue to fuel the anosmia market. As governments and healthcare systems prioritize long-COVID care, funding and innovation for olfactory rehabilitation are accelerating.

Regional & Segment Dynamics

·         North America is expected to maintain dominance throughout the forecast period. The region benefits from a strong healthcare infrastructure, high diagnosis rates of anosmia, and significant R&D investments.

·         Asia-Pacific, while not leading in 2023, is poised for notable growth due to rising healthcare awareness and increasing accessibility to olfactory therapy in emerging markets.

·         By cause, viral infection (including COVID-19) leads, but head trauma also commands a large share given the prevalence of traumatic brain injury and advances in neurological treatment.

·         By treatment, the market is segmented into medical therapy, surgical intervention, and olfactory retraining, with retraining gaining strong traction as a patient-friendly, cost-effective modality.

Expert Insight

“The anosmia market is entering a transformative phase,” said Dr. Raghav Verma, Principal Consultant, Life Sciences, at Introspective Market Research. “We are seeing the convergence of AI diagnostics, wearable olfactory sensors, and regenerative therapies, which together are helping to close the gap in managing chronic smell loss  especially for post-COVID patients. However, the lack of scalable, affordable therapies for irreversible anosmia remains a significant hurdle for broad adoption.”

Innovations & Breakthroughs

Recent developments from leading biopharma companies are shaping the future of anosmia treatment:

·         AbbVie has ramped up research into neuro-regenerative approaches to restore olfactory neurons.

·         AstraZeneca and Novartis are exploring small-molecule therapies targeting olfactory epithelium repair.

·         Pfizer and Sanofi are advancing clinical programs in olfactory retraining devices and fatigue-resistant screening kits.

Although our public-facing report does not disclose proprietary case studies, Introspective’s internal research includes real-world evidence of patients regaining smell function following structured olfactory retraining, particularly in post-viral anosmia cohorts.

Opportunities: Where the Market Could Expand Further

·         Regenerative medicine: Significant opportunity lies in therapies aimed at repairing or regenerating olfactory tissue, especially for irreversible cases.

·         Diagnostic democratization: AI-enabled and wearable diagnostics could lower barriers to early detection, particularly in low-resource settings.

·         Public health screening: Incorporating smell evaluation into routine clinical checkups may lead to earlier identification of anosmia, improving outcomes.

·         Long COVID programs: Governments and healthcare systems investing in long COVID can integrate anosmia rehabilitation to meet patient needs more comprehensively.
