By the numbers
Updated October 2026- Approximately 20 million Americans are currently diagnosed with food allergies, driving a 25% increase in demand for oral immunotherapy (OIT) since 2022 (AAAI).
- Over 100 million Americans experience various types of allergies each year, making it the 6th leading cause of chronic illness in the U.S. (ACAAI).
- Nearly 60% of patients with moderate-to-severe asthma are now eligible for targeted asthma biologics, significantly reducing emergency visits (CDC).
- Prescriptions for Sublingual Immunotherapy (SLIT) have grown by 15% annually as patients seek needle-free alternatives to traditional allergy shots (AAOA).
Trending this month: Patients are increasingly opting for Oral Immunotherapy (OIT) and SLIT for long-term desensitization. The rise in biologics for asthma and eczema is also notable as patients prioritize precision medicine that targets root causes rather than just symptoms.
How to choose the right specialist
Verify board certification, ask how many of your specific procedure the clinician performs each year, and review patient outcomes — not just star ratings. A allergists provider who clearly explains your options, the evidence, and the realistic recovery timeline is worth more than the most heavily advertised name.
