Managing Allergies for Better Health

Allergies occur when the immune system overreacts to triggers such as dust, pollen, animal dander, or certain foods.

Symptoms by system: respiratory — sneezing, runny or blocked nose, itchy eyes (allergic rhinitis); skin — itchy or red rashes, dry flaking skin; digestive — bloating, diarrhoea, or lip swelling from food allergy.

Care focuses on identifying and avoiding triggers, keeping bedrooms clean, using air purifiers when helpful, and taking medicines as prescribed during flares.

Food intolerance can differ from acute allergy: symptoms often build gradually — bloating, fatigue, or headaches after certain foods.

PNC offers IgG testing for 222 foods with nutrition guidance; ozone therapy and vitamin C IV may support immunity alongside dietary change.
