Sensitivity (intolerance) to sulphites

  1. Sulphites (E numbers E220 to E228) are chemicals commonly used as preservatives for various foods and drinks. In addition, some medicines contain sulfites, which is necessary to keep the medicines stable and effective. Sulphites are also found in cosmetics. Companies must place on their labels that the food, drink or medicine contains sulphites as some patients react sensitively to this substance. They suffer from a sensitivity (intolerance) to sulphite. Problems with the skin, digestion and heart and lungs may manifest themselves. In severe cases breathing problems arise. Rapid treatment is necessary. Patients with this type of intolerance should avoid sulphites. Finally, a few tips prevent a new hypersensitivity reaction.

Sources of sulfites

  1. Sulphites are found in medicines, foods and drinks as well as cosmetics.

Medication

  1. Sulfites are added to many prescription and over-the-counter medications:

Food and Beverage

  1. Many products may contain naturally occurring or added (E numbers E-220 to E-228) sulphites such as:

Sulphite sensitivity terminology

  1. People usually speak of a sulphite allergy. In principle, however, there is a hypersensitivity reaction to sulphites (intolerance to sulphite). The immune system is always involved in an allergy and this is not the case when a hypersensitivity reaction occurs.

Causes of hypersensitivity reaction to sulfites

  1. The cause of a sensitivity to these chemicals is unknown in December 2019.

Risk factors of type of intolerance reaction

  1. A sensitivity to sulphite rarely occurs. Patients with asthma are at an increased risk of a reaction to these chemicals.

Symptoms

  1. Some patients react sensitively to sulphites and suffer from hypersensitivity reaction after consuming or applying this preservative. The mild to severe symptoms vary and include:

Diagnosis and investigations

  1. The diagnosis of sulphite sensitivity is made by an allergist. Namely, he performs a food challenge test. In this type of intolerance reaction, the patient is then administered a very small amount of sulphites in the hospital. The doctor then follows him closely to detect any possible reaction immediately. If a patient has no symptoms, the doctor slowly increases the amount the patient is receiving. If a patient has a reaction, the patient is given drugs to reverse the symptoms. Investigations are also necessary to check lung function.

Treatment of sensitive reaction to chemicals

  1. The dietician or nutritionist also provides the patient with nutritional tips and advice on the prevention of hypersensitivity reactions. If signs of a severe hypersensitivity reaction, medical attention is required immediately.

Prevention of sulphite intolerance

  1. Reading the label is always important when patients react sensitively to sulphites. Patients should avoid these chemicals. Furthermore, patients can be best prepared. They should always bring emergency medication if they have ever had anaphylaxis. Furthermore, it is recommended to wear a medical alert bracelet so that people in the vicinity can be warned that the patient is suffering from an intolerance reaction.
