Living With Constant Reactions
Sneezing, itchy eyes, and congestion may seem like minor issues at first, but for many people, allergies create daily discomfort that disrupts work, sleep, and concentration.
Over-the-counter antihistamines or nasal sprays may mask symptoms, but they don’t address the underlying sensitivities that keep your immune system on high alert.
At Delaware Functional Medicine and Longevity, Dr. David M. Creech helps patients in Wilmington uncover the causes of allergic reactions. With functional medicine techniques, he works to calm the immune system and reduce symptom flare-ups.

What Triggers Allergies?
Allergies occur when the immune system overreacts to substances that are normally harmless. These “triggers” vary from person to person and may include:
- Pollen, grass, and tree allergens
- Dust, pet dander, and indoor irritants
- Foods such as dairy, gluten, or soy
- Additives, dyes, or preservatives in processed foods
- Environmental toxins like mold or chemicals
Instead of focusing only on symptom management, functional medicine looks for the root of immune overactivity.
Benefits of Addressing Allergies With Functional Medicine
When triggers are identified and managed, patients often experience:
- Fewer seasonal allergy flare-ups
- Reduced congestion, sinus pressure, and headaches
- Less dependence on daily medications
- Clearer breathing and improved sleep
- More energy and focus during the day
By calming immune overactivity, patients also support overall wellness, not just allergy relief.
Who Needs Allergy Care?
You may benefit from functional medicine evaluation for allergies if you:
- Struggle with persistent seasonal or year-round allergy symptoms
- Have tried medications with limited results
- Experience food-related reactions such as bloating, rashes, or fatigue
- Want to understand the immune system’s role in your sensitivities
- Prefer a long-term strategy instead of daily symptom management
Our Approach to Allergy Relief
Care begins with a thorough consultation and testing. Dr. Creech may recommend allergy panels, food intolerance testing, or environmental assessments. Based on results, your plan may include:
- Adjusted diet to reduce food triggers
- Strategies to limit environmental exposures
- Supplements to balance immune activity
- Stress and sleep support to reduce flare-ups
- Use of recovery therapies like sauna for detoxification support
This approach ensures care is personalized rather than one-size-fits-all.
