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.
