Food Intolerances & Food Allergies

Food intolerances and food allergies

Food intolerances and food allergies are very common causes of digestive disorders and symptoms that most patients do not associate with food (such as migraines, eczema, asthma, etc.). In general language usage, food allergies and intolerances are often equated, but there are significant differences between them.

True immediate-type allergies with classic symptoms like swelling of the mucous membranes, difficulty breathing, facial swelling, teary eyes, or even anaphylactic shock are relatively rare, occurring in 2-4% of the population. In these cases, strict avoidance of the respective allergenic foods is often necessary. If the allergy is not obvious (e.g., apple allergy), the diagnosis can be challenging and may require blood tests, skin tests, or even provocation tests with suspected allergens.

On the other hand, intolerances are much more common, and although they do not typically have acute and dramatic symptoms, they can significantly impair quality of life and overall health.

The causes of food intolerances are not uniform. The body can, for example, produce specific antibodies (IgG4 antibodies) against certain foods, or there may be enzyme deficiencies (such as lactose intolerance or histamine intolerance).

The medical history (anamnesis) forms the basis for further diagnostic steps. Enzyme deficiencies causing food intolerances can be diagnosed through urine tests, blood tests, stool tests, and breath tests after provocation. The therapy involves reducing the consumption of the respective foods to a tolerable level and, if necessary, supplementing the lacking enzymes with suitable preparations (e.g., Lactrozym for lactose intolerance, Fructozym for fructose intolerance, and DAOzym for histamine intolerance).

The detection of the commonly occurring IgG4 food intolerances is much more challenging. The symptoms are often atypical for an allergy and can range from bloating, changes in bowel movements, headaches/migraines, fatigue, eczema, asthma, to joint pain, and more.

The underlying cause is usually a leaky gut lining due to damage to the intestinal flora. This allows larger protein components from food to enter the bloodstream, triggering the production of IgG4 antibodies by the body. These antibodies form insoluble complexes with the protein components, which can damage various structures in the body and trigger corresponding symptoms.

Diagnostically, such intolerances can be detected through extensive blood tests or bioenergetic diagnostics. The therapy involves temporarily avoiding these foods for a period of 1-6 months. During this time, the body can break down the existing IgG4 antibodies.

Simultaneously, the intestinal mucosa must be restored to prevent the recurrence of intolerance. The treatment is complemented by additional bioresonance therapy, which significantly reduces the body's tendency to develop allergies.
