Why Choose Dr. Laura Ispas
Allergic rhinitis, or hay fever, causes nasal inflammation from airborne allergens, leading to sneezing, congestion, runny nose, and itchy eyes, occurring seasonally or year-round in sensitive individuals worldwide.
Asthma is a chronic lung condition where inflamed, hypersensitive airways narrow, causing wheezing, coughing, chest tightness, and shortness of breath when triggered by allergens, exercise, or infections across all ages.
Allergy shots gradually expose your immune system to small, increasing allergen doses, building tolerance over time so reactions lessen or stop, providing long-term relief through structured build-up.
Food allergies occur when the immune system reacts to specific foods, causing symptoms from hives to anaphylaxis, affecting children and adults, sometimes developing later in life unexpectedly without prior exposure.
Eczema, or atopic dermatitis, is a chronic skin condition marked by itchy, red inflammation, common in children but possible at any age, often associated with allergies, asthma, and periodic flares.
Before your allergies can be properly treated — and especially if you’re considering allergy shots — you must need to undergo skin testing to determine which substances cause your allergies.
