Allergies occur because your immune system is incorrectly activated by the wrong things, like dust, pollen or foods. People with allergies have an immune system which is not too weak, but rather is overactive and therefore results in many of the symptoms typically associated with a cold including runny nose, congestion, ear pressure, post nasal drainage, fatigue, facial pain and facial pressure. People with allergies are more susceptible to sinus infections, ear infections and bronchitis due to excess mucus production and trapping of mucus in the sinuses and middle ear.
A fascinating aspect of allergies is the unique presentation in each person. Every allergy has a specific target organ. For example, one person’s dust mite allergy may cause chronic itching, while another person’s dust mite allergy may cause itchy eyes, runny nose and congestion. Similarly, one person’s wheat allergy may cause chronic constipation, while another person’s wheat allergy may cause chronic congestion and sinus infections.
Substances that often cause reactions include:
