What Allergies Cause Asthma?

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.
