Inhaled Allergens. The most important allergens
for people with allergic asthma appear to be those asthma triggers that
are inhaled. Hay fever or seasonal allergic rhinitis occurs when an
allergen comes in contact with a substance that a person is sensitive
to. Common inhaled allergens include:
- Animal dander (skin, saliva)
- Dust mites
- Cockroach particles
- Mold
- Pollen
Medical experts recommend that all people with allergies and
asthma try to identify possible inhaled allergens that may trigger
asthma symptoms.
Food Allergies. Food allergies rarely cause
asthma yet they can cause a severe life-threatening reaction. But, the
most common foods associated with allergic symptoms are:
- Eggs
- Cow's Milk
- Peanuts
- Soy
- Wheat
- Fish
- Shrimp and other shellfish
- Salads & fresh fruits
Food preservatives can also trigger asthma. Additives, such as
sodium bisulfite, potassium bisulfite, sodium metabisulfite, potassium
metabisulfite, and sodium sulfite, are commonly used in food processing
or preparation and can be found in foods such as:
- Dried fruits or vegetables
- Potatoes (packaged and some prepared)
- Wine and beer
- Bottled lime or lemon juice
- Shrimp (fresh, frozen, or prepared)
- Pickled foods
In most people, the usual symptoms of food allergy are hives,
rash, nausea, vomiting, and diarrhea. If you have a food allergy that
triggers an asthma attack, you will likely experience these allergy
symptoms, followed by wheezing. And if not caught quickly, anaphylaxis
-- swelling of the throat, cutting off the airway -- may result.
If you suspect that certain foods may be the cause of your
asthma, discuss this with your doctor. Allergy skin testing can be done
to determine if you are allergic to these foods.
