What Are Symptoms of Sulfite Allergies?

Sulfite allergies are mostly found in individuals with asthma, and especially those asthmatics who are steroid-dependent. Though sulfite allergies are not common in people without asthma, those who have compromised kidney and liver function must also be aware of the symptoms of sulfite allergies.

Respiratory

• The most common respiratory sulfite allergy symptoms are bronchial spasm, wheezing, tightness in the chest, and possibly severe asthma attacks

Oral/External

• After ingesting a sulfite, you might experience flushing and feel a rise in temperature, hives, swelling of the face or mouth and have trouble swallowing.

Abdominal

• As with most food-related allergies, sulfite allergies might affect your stomach, causing you to have stomach pains, diarrhea, nausea and vomiting.

Vascular

• You may experience dizziness from a drop in blood pressure, which may fall low enough to cause you to pass out.

Severe

• Anaphylaxis and anaphylactoid reactions can be experienced by persons with or without asthma, though it is rare. The biggest risk is a severe asthma attack.

Warning

• Individuals with liver and kidney impairment may not produce the enzyme that is needed to break down sulfites, which can cause a sulfite excess and the development of sulfite-allergy-like symptoms.
