Main causes of chronic allergies:
Immune System Overreaction (main cause):
The body’s immune system mistakes normal substances that do not cause any harm to the body (for example: dust, pollen, certain foods) as harmful substances, and produces antibodies (IgE) against them and releases chemicals such as histamine, causing allergy symptoms.
Genetics & Family History:
If parents or close relatives have allergic problems such as asthma, eczema, and hay fever, then the risk of these problems passing on to children is very high due to genetic reasons.
Environmental Allergens / Triggers:
Dust Mites: Microorganisms found in dust mites and bedding in homes.
Pollen: Pollen that is spread by the wind from plants and trees.
Pet Dander: The hair and skin flakes of animals such as cats and dogs.
Mold: Mold spores that grow in damp places and on walls.
Air Pollution & Smoking:
Constantly breathing in smoke, dust particles, gases from factories, and cigarette smoke in the atmosphere can affect the lungs and nasal passages and cause chronic allergies.
Food Allergies:
Some people may have an allergic reaction to certain foods such as milk, eggs, peanuts, soybeans, fish, and meat.
Weather Changes:
Some people experience persistent allergies such as sneezing, congestion, and itchy skin during cold or rainy seasons or when the humidity in the air changes suddenly.
Use of Chemicals & Cosmetics:
Soaps, perfumes, hair dyes, and chemicals used for cleaning the house can cause persistent allergies when they come into contact with the skin or lungs.
